April 29, 2003 - New drop: DEVELOPMENT FOX 1.1.26
 |
Stuff in this development snapshot.
- Changed addTimeout() to replace the old timer, if it exists, with the
new timeout value. This simplifies code as you can simply set the timer
and if it was set already it now gets reset to the new interval.
- Changed addChore() of course to do the same; it re-appends the
chore at the end of the list, basically postponing it until after the
outstanding chores have been performed.
- Fixed forgotten header file include in FXApp for WIN32 build.
- Replaced hard-coded "0" with DefaultScreen(display) in FXVisual;
this caused problems on X11-based systems having more than 1 screens.
- Removed private GetDC() and ReleaseDC() API's (WIN32 only).
- Fixed FXDCWindow problems:- surface->id() shoule now be treated
correctly everywhere based on type of surface.
- Added support for thread-safe build (using POSIX thread-safe
functions like readdir_r()). Enabled by passing -DFOX_THREAD_SAFE=1
on the command line. Using the thread-safe library calls ensures that
the GUI thread never interferes with the worker threads if the worker
threads are making certain kinds of library calls (of course, you might
want to ensure the worker threads also call the thread-safe API's so
that they won't interfere with each other!).
NOTE: this feature is not supported on SGI IRIX 6.x!
- Replaced virtual getText() functions in FXListItem (and other list widgets)
by non-virtuals which yield const FXString&, this eliminates a lot of string
copying. Returning const FXString& is safe as FXListItem's API's
are chiefly for FXList and its subclasses to use and not usually directly
used by application programs.
- Expunged deprecated fxgetusername(), fxgetgroupname(), and fxgetpermissions()
API's from fxdefs.h. Use the safer equivalent functions from FXFile instead.
- Removed deprecated setPatternList(const FXchar **ptrns) from FXFileDialog
and FXFileSelector. The new function is easier to use and harder to
abuse.
- Fixed FXText widget:- get selection from clipboard returns value of len larger
than actual text length; now we're just scanning till the end of string to determine
the real length.
New in this release.
- Changed the way timers are set or removed. The method addTimeout() is basically
the same as before, except has a small change in argument-order (permitting default
parameters more easily). An overloaded removeTimeout() removes timers by means of
the same target and message combination as the corresponding addTimeout(). This
new method is very convenient as it eliminates to a large degree the bookkeeping
necessary to hang on to the FXTimer pointer.
- Also, addTimeout() now has an optional pointer argument, which is passed back
as the void* pointer in the callback. This way, information may be passed from the
place where the timer is set to the place where the timer callback is called.
Note that the pointer in the timer callback handler no longer
refers to an FXEvent!
- Similarly, changed the way chores are handled; the new overloaded removeChore()
removes a chores by means of the same target and message as the matching addChore() was
invoked with. Again, this simplifies coding in many cases.
- Like the timers, addChore() also adds an optional pointer argument, which is
passed to the chore callback handler when the chore is fired.
Note that the pointer in the chore callback handler no longer
refers to an FXEvent!
- Updated all widgets which have timers and chores to use the new timer system;
all such widgets are now simpler in implementation and actually take a bit less
memory as well.
- Implemented delayed layout update using chores. Previously, a change in layout
was reconciled using a GUI-Update pass. The new system replaces this by a simple chore
being set, and thus a layout change no longer incurs an iteration over the entire widget
tree. This means layout changes are now substantially less CPU intensive (and
faster too!).
- Made layout() a public member function. I had to do this, because the new
method to force an immediate layout is no longer performed via forceRefresh().
If you need immediate layout, then you must now just call layout()
directly!
The member function forceRefresh() now only performs a GUI-Update pass on the
subtree of the widget on which it is called!
- The message handler onUpdate() no longer invokes layout(). This actually
will speed the GUI-update pass up a little bit, as the new GUI-Update implementation
will not call layout() anymore.
If, as a result of a GUI-update, widgets change size (for example caption on a
label is changed), then there will be no need for an additional GUI-update pass
for the layout. The result again is substantially less CPU time wasted during idle
processing, and a more responsive application.
- Implemented delayed layout during window-resizing.
When resizing dialogs, the system previously rearranged the widgets in the dialog
immediately. As a result of this, an interactive (opaque) resize of a complex widget
tree could start to fall behind the mouse movement.
With the new system, it is no longer possible to fall behind, because now it delays
arrangement of the widgets until it has caught up with the event-stream.
This makes opaque resizing complex GUI's on slow machines much faster.
Note that this delayed layout is implemented on X11 only; under WIN32, the
new delayed layout method appears currently impossible).
- Added some missing API's to FXWString.
- Fixed a buglet in FXString::substitute(). The last occurence of a substring
ending the string was not being substituted.
- Fixed a few other bugs that had been reported.
March 13, 2003 - New drop: DEVELOPMENT FOX 1.1.24
 |
Stuff in this development snapshot.
- FXFileList now supports case insensitive as well as case sensitive sorting when
sorting by names. It supports two new sort functions for this.
- FXFileList also directly accepts a new message ID_SORT_CASE to toggle case-sensitive
sorting. The default is now to sort case-insensitively.
- The sort functions have been renamed with more human-readable names.
- FXText and FXTextField now support a new ID_DELETE_ALL message. As the name
indicates, it deletes all the text in the widget.
- Some initial support for OpenWatcom C++ has been added.
more to come in the future.
- FXRuler is progressing. You can get an idea what it will look like now.
- FXGLVisual now thinks a visual with RGBA is OK even if you asked for RGB.
Some high-end video cards (ATI) support RGBA and no RGB. For those that do, RGB is
preferred over RGBA if you asked for RGB.
- FXFileDialog's right-mouse menu offers case-ignore as an option; so does PathFinder.
February 25, 2003 - New drop: DEVELOPMENT FOX 1.1.23
 |
Of course, all bugs from the STABLE release are now also fixed in the DEVELOPMENT release.
Other news:
- FXDLL should now compile properly.
- FXSettings keys and section names are now no longer allowed to be NULL or empty.
- FXCheckButton gained a new option, CHECKBUTTON_PLUS, with which you can change
the appearance from a check to a plus or minus box similar to FXTreeItem;
the intended use of this feature is to connect FXCheckButton to a layout manager,
whereby the layout manager can be collapsed or expanded via the ID_TOGGLE_SHOWN
method; for this reason the plus-sign is shown when the state is FALSE, i.e. when
the associated layout manager is collapsed.
- FXTable has two new API's, getMinRowHeight() and getMinColumnwidth() which compute
the minimum height or width of a row or column in the table based on the contents of the
items; this substantially simplifies setting up a sensible initial table display.
- FXTableItem's getHeight() and getWidth() now yield sensible values; your subclass
of FXTableItem should overload them if the size computation needs to be different.
There have been a few changes to the FXGLViewer:
- Dropped the SURFACEPROJECTION and SURFACEPROJECTION display lists; the reasons were
two-fold: first, display lists may be shared between FXGLViewers and it was never
clear whose projection matrices were in the display lists; second, there is a better
way to obtain the desired effect in the form of the OpenGL 1.1 Polygon Offset
extension; since OpenGL 1.0 is ancient history now, the time seemed ripe to ditch
the old method.
- FXGLViewer now supports a gradient background; this is simply enabled by
setting the top and bottom background color to different values; setting them
to the same values will revert to the uniform background mode.
You can connect an FXColorWell to the upper and lower gradient color and control
the gradient easily from your GUI.
The default gradient background is a blue-sky; most people would like this I hope.
- The VIEWER_LOCKED feature has been removed; we found no one was ever using
it and it was not so useful anyway.
- We now try a little bit harder getting the OpenGL context into a known
state before calling scene->draw(). This is partly because we need it for
the gradient background drawing.
- Support for shift-click and control-click selection, as well as shift-lasso
and control-lasso is now being improved; the FXGLViewer can distinguish between
them based on mouse movement: if the mouse moves, its a lasso otherwise its a
click. While not entirely finished yet, the basic idea is to give FXGLViewer
similar callbacks as the list widgets, and give the application more control
over the interpretation of the mouse events.
Other issues:
- Slight problem in FXLabel and a few similar widgets fixed: FXString now
remembers its length, and this should be used to find the end of the string.
- Fixed almost all compiler warnings (Linux, GCC 3.2). ANY warnings
still left in the code are intentional! Don't complain about them,
they will be fixed when the time comes!!
- Adie is still broken, sorry! Use the version in the STABLE RELEASE!
It is still under development, but I'm kind of busy right now so its taking more
time than I would have liked.
- PathFinder gained some nice Preferences Panel; more is coming. The current
version of PathFinder is not finished, but the functionality that's there
is stable and solid.
- The initial precision in the FOX calculator has been dropped to 15 digits;
some people complained about roundoff errors (of course, double precision is
only accurate down to about 16 digits so roundoff errors in the 16th digit
are to be expected). I dropped the precision down to 15 because I don't like
to explain this repeatedly!
February 25, 2003 - New drop: STABLE FOX 1.0.34
 |
Over the course of the last week, a number of minor issues have surfaced which
are now fixed.
- FXFileDialog now sets both anchor and current file to the same when you suggest an
initial filename when opening a file. Thus, a sunsequent shift-click in multiple select
mode now indeed highlights all files between the suggested selection and the one you
click on; a minor thing but an annoyance to some.
- FXTextField could not easily tolerate contents exceeding a few thousand characters;
this was the result of both X11 and WIN32 internally working within a 16-bit coordinate
system; this caused trouble drawing and highlighting the text inside FXTextField.
The fix to figure out which characters of the string have a remote possibility of
falling inside the visible area, and then only drawing those. As a side-effect,
the amount of data in the drawing protocol is now also substantially less in such cases
resulting in faster drawing.
- An accelerator Ctl-A has been added to FXFileDialog to select all files. Many
people will find this convenient. Also, you can select all files from the righ-mouse
popup menu.
- The test in FXText in API extractStyle() and extractText() was a bit too strict;
it is not necessary for the return buffer to be non-NULL if the amount of text to be
extracted is zero-length.
- A small typo has crept in FXRex in the match() API; a forward case-insensitive
match would sometimes not work correctly.
February 22, 2003 - New drop: STABLE FOX 1.0.33
 |
- Minor bug in FXFileDialog: when in multiple file selection mode, FXFileDialog::getFilename()
was not returning a sensible value. This caused various kinds of mayhem in different
places. The new implementation returns FXString::null when no files were selected, or
returns the first selected file in multiple selection mode, or the value in the text box
when in single selection mode.
February 19, 2003 - New drop: STABLE FOX 1.0.32
 |
- Updated FXFileList; when no extension is bound, the file extension string becomes the extension of the file name. This permits sorting by extension even for files with no association.
- Fixed bug in FXText; space-terminated last line could not be clicked by mouse.
- Bug in FXRex fixed; incorrect behavior in forward match case-insensitive literal string.
- Wrong callback message type in FX4Splitter.
January 15, 2003 - New drop: DEVELOPMENT FOX 1.1.22
 |
- Updated FXDirList for unlimited path lengths. We found MAXPATHLEN to be exceeded in some case, just like FXFileList. Also, FXDirList now properly lists drives under Windows. Periodic scanning now happens non-recursively.
- Renamed FXTreeList::sortItems() to FXTreeList::sortRootItems().
- Added API's to move items around in FXTreeList.
- Added API's to move items around in FXList and FXIconList.
- Added API's to FXSpinner to set arrow colors.
- Added new API's for loading DLL's or dynamic libraries:
- fxdllOpen(). Opens a DLL with given name, returning a handle.
- fxdllClose(). Closes DLL with the given handle.
- fxdllSymbol(). Returns symbol in the DLL with the given handle.
- This has only been coded for Linux and Windows. Other platforms will still need some work. Note that fxdllOpen() may be called multiple times on the same library name. We're counting on the underlying O.S. to reference count (Linux and Windows both do!).
- Added API to FXApp to return drag window. This may be useful to determine which window is currently a drag source. Also added API to FXApp to see if FXApp was already initialized.
- Added API to FXFile to return root of a path. On UNIX, this is only "/" but on Windows this may be something like "c:" or "\\".
- Fixed FXString::vformat().
- In a few days, fox-toolkit.org may go down for an unspecified amount of time as my DSL provider has gone under. Grab it while you can. Otherwise, visit the mirror site:

- HTTP: http://www.fifthplanet.net/fox/fox.html
January 9, 2003 - New drop: STABLE FOX 1.0.30
 |
- Minor bug fix:- fixed FXString::vformat(); vformat() uses vsnprintf() if available, vsprintf() otherwise. The former is buffer-overrun safe. Some systems have different symantics for vsnprintf(), and FOX now compensates for this.

December 23, 2002 - New drop: STABLE FOX 1.0.29

- Fixed drawing bug in FXTreeList. Drawing with TREELIST_SHOWS_BOXES but no
- TREELIST_SHOWS_LINES was all messed up.
December 5, 2002 - New drop: DEVELOPMENT FOX 1.1.21
 |
- Added new API's to FXString:
- substitute() substitute one substring by another.
- contains() count possibly overlapping occurences of a substring in the string.
There are several overloads for these functions.
- Clarified some documentation in FXApp, FXWindow.
- Updated FXFileList to allow it to work with arbitrarily long file names, user names, group names, and directory names. Some people had paths longer than MAXPATHLEN and this caused problems.
- Moved JUSTIFY_XXX options from FXLabel to FXFrame; various subclasses of FXFrame use these flags (but FXFrame itself does not, as it has no contents!).
- Added support for JUSTIFY_XXX in FXImageFrame.
- Added API FXFile::linkinfo(), which stats the link and not the file the link refers to.
- Added flags TEXTFIELD_AUTOGRAY and TEXTFIELD_AUTOHIDE to FXTextField, enabling it to automatically gray (or hide) when its target does not respond to SEL_UPDATE messages. This is very useful when messages are routed around, e.g. via MDI widgets.
- Added new widget, FXTriStateButton, which can assume three states (false, true, and maybe), where the maybe state is usually only reached programmatically or by means of SEL_UPDATE handlers. You can use this widget whenever your application calls for a toggle type button which may have indeterminate state.
- Fixed small buglet in FXTextField; in rare cases, cursor position was outside of text.
- Fixed bug in fxcpuid() implementation:- according to SYSV x86 ABI, EBX is used when compiling PIC for shared libraries; the initial implementation of fxcpuid() was usurping EBX for other uses. The x86/Linux-only API fxcpuid() returns some flags which detect various interesting features of your x86 CPU, such as SSE, SSE2, MMX, MMXEX, 3DNOW, 3DNOWEXT, and TSC presence.
November 20, 2002 - New drop: STABLE FOX 1.0.28
 |
- A minor bug has been discovered in the BMP reader; sanity checking code erroneously rejected 4 bit/pixel RLE compressed bitmaps; apparently, these are pretty rare :-).
- Fixed small buglet in FXOptionMenu:- GUI Update becomes disabled after manipulation of the option menu in some scenarios.
- FXSettings had spelling error in warning message.
- Small bug in FXFile::simplify(); simplify("c:\..\") became "c\" instead of "c:\".
November 13, 2002 - New drop: DEVELOPMENT FOX 1.1.20
 |
- Added nifty API's to FXImage:
- fill() fill image with a constant color.
- hgradient() fill image with a horizontal gradient using two colors.
- vgradient() fill image with a vertical gradient using two colors.
- gradient() fill image with a bi-linear gradient using four different colors.
- fade() fade an image to a given color by a certain factor.
- blend() blend (transparent) image over a given color.
Stay tuned for more image manipulation API's!
- Added performance (LINUX/GCC/GAS/x86 only) API's:
- FXlong fxgetticks() reads Pentium/Athlon time stamp counter register. This register increments one unit each single clock (for example on my Athlon 1600+ this means 1,400,000,000 ticks/second!). Very useful to settle heated arguments about whose code is faster :-)
- FXuint fxcpuid() determines presence of "interesting" CPU features such as MMX, MMXEX, 3DNOW, 3DNOWEXT, SSE, SSE2, and presence of Time Stamp Counter register.
You can use this function if:
- You're using GCC/GAS/x86.
- You want to whip up some cool inline MMX, 3DNOW, or SSE(2) code.
If you're not using GCC and GAS, you'll have to do without!
- Fixed small introduced bug in FXTextField:- when replacing selection, old cursor position was sometimes out of range.
- Fixed small problem in FXFile. FXFile::absolute("c:\..\") was yielding "c\" instead of "c:\".
- Added feature to FXHeader:- when clicking on split between captions, a SEL_CLICKED message is sent to the target.
- Added feature to FXIconList. When receiving a SEL_CLICKED message from FXHeader, FXIconList recomputes the minimal required space for the caption, given the current list of items in it.
- Made slight change to behaviour of FXTextField. When replacing selection by another string, only a single callback message now results.
- Added getNumOptions() API to FXOptionMenu. FXOptionMenu also sends a SEL_COMMAND message now after completion of the interaction. Also fixed GUI updating of FXOptionMenu.
October 30, 2002 - New drop: DEVELOPMENT FOX 1.1.19
 |
- Changed workings of FXMALLOC() and co. again; the initial theory, I have to admit, was flawed and impractical; the new workings however are far more practical:
FXMALLOC(ptr,type,no)
Allocate no elements of type to the specified pointer.
Return FALSE if size!=0 and allocation fails, TRUE otherwise.
An allocation of a zero size block returns a NULL pointer.
FXCALLOC(ptr,type,no)
Allocate no elements of type to the specified pointer, and clear this
memory to zero.
Return FALSE if size!=0 and allocation fails, TRUE otherwise.
An allocation of a zero size block returns a NULL pointer.
FXRESIZE(ptr,type,no)
Resize a previously allocated block of memory.
Returns FALSE if size!=0 and reallocation fails, TRUE otherwise.
If reallocation fails, pointer is left to point to old block; a reallocation
to a zero size block has the effect of freeing it.
FXMEMDUP(ptr,type,src,no)
Allocate and initialize memory from another block.
Return FALSE if size!=0 and source!=NULL and allocation fails, TRUE otherwise.
An allocation of a zero size block returns a NULL pointer.
FXFREE(ptr)
Free a block of memory allocated with either FXMALLOC, FXCALLOC, FXRESIZE,
or FXMEMDUP.
It is OK to call free a NULL pointer.
- Fixed harmless bug in FXTable.
- Removed radio and check behavior from FXMenuCommand; this functionality is now assumed by FXMenuRadio and FXMenuCheck.
October 26, 2002 - New drop: DEVELOPMENT FOX 1.1.18
 |
- Fixed argument test in FXText:- NULL text argument is allowed if size is zero.
- Fixed drawing bug on MS-Windows in FXMenuRadio.
- Fixed potential buffer overrun in FXFont.
October 25, 2002 - New drop: DEVELOPMENT FOX 1.1.17
 |
- Changed FXMALLOC(), FXRESIZE(), FXCALLOC() macros very slightly; FXCALLOC() and FXMALLOC() new always return a NULL pointer and a FALSE return value when a zero size is passed; previously, this depended on the underlying malloc() implementation of the operating system, and operating systems varied in this behaviour. Also, FXRESIZE() returns a NULL pointer and FALSE return value when resizing to zero size; again, operating systems varied in this behaviour. With these changes, it works the same on all operating systems.
- FXIconList, FXList, FXTreeList was trapping KEY_Delete; this prevented a KEY_Delete from being used as an accelerator.
- FXTable was not compiling with Borland C++ builder. Fixed.
- FXMetaClass destructor was not releasing hash table properly; moreover, was causing divide by zero in a few cases. The new implementation releases all memory and can't possibly divide by zero, because the modulo operator has been replaced by bit-wise and; this is possible because the hash table is always a power of two.
- FXFile Dialog has accelerator for delete file.
- All messages should now use the new FXSEL, FXSELTYPE, and FXSELID macros. Note FXSEL has the arguments reversed, and the argument order is now the same as the one used in FXMAPFUNC and FXMAPFUNCS; hopefully, this is easy to remember.
October 8, 2002 - New drop: DEVELOPMENT FOX 1.1.16
 |
- Regressed API's to return FXString rather than const FXString&, for the following reasons:
- Not consistent. Some API's *compute* their returned FXStrings, so you're always going to have some API's which can never return const FXString& anyway; but conversely ALL API's can return FXString no matter what, so if its consistency we want then the old way is the only way!
- I don't want to encourage people hanging on to pointers into the private member data of classes; see previous mail on this topic; this reduces my ability to change internal representations of widgets.
- Its not as painful (in terms of run time) as it looks:- many access functions are inlines, and the compiler can decide to eliminate a few copy constructors (if not automatically, then at least with some encouragement like the option "-felide-constructors" for GCC ).
- Once all widgets store FXWString internally, you will really thank me for this:- because if we do it the old way, your software can remain unmodified (thanks to conversion operators between FXString and FXWString), but if we go the via the "const FXString& " route then all the software which tries to take advantage of your trick would have to be rewritten!
- Added API's to FXTable to control item appearance:
- setItemJustify() changes justification
- setItemIconPosition() changes icon position relative to the text
- setItemBorders() changes item's border style
- setItemStipple() changes item's stippling
- Added patch from Petri Hodju for FXToggleButton's TOGGLEBUTTON_KEEPSTATE implementation. When this flag is passed to FXToggleButton, the button stays pressed if the state is TRUE.
- Removed __FXMETACLASSINITIALIZER__ from FXObject.h. FXMetaClass is now made into a proper class instead of a struct. At startup time, the FXMetaClass's constructor adds the class to the hash table of meta classes, and at termination time the FXMetaClass's destructor takes the class back out.
This means if you build DLL's with FOX classes in them loading and unloading the DLL will properly add or remove the class names from the hash table.
This will allow objects to be serialized/deserialized even if they're in a DLL! The only thing left to do is to use the escape code in FXStream to actually load the DLL and we have a proper Plug-In architecture.
- Fixed fxmalloc(), fxcalloc(), and fxresize() so that they return NULL when the desired size is zero; straight malloc() will not do that on all systems.
October 3, 2002 - New drop: STABLE FOX 1.0.26
 |
- Janusz Ganczarski found a very minor bug in the PCX loader code; some PCS images failed to load because of this.
- Fixed bug in FXFile (MS-Windows) in recursive copy routine (see previous announcement).
- Bug in FXToolbar getDockingSide().
- Fixed some stuff in FXTable w.r.t. spanning cells.
- Fixed some stuff related to file time in FXDirList; also, handle was not being closed at the right time, preventing timely directory refreshing; finally fixed sporadic crash.
- Window coordinates and size not updated at the right time (MS-Windows) relative to the SEL_CONFIGURE message being issued.
October 2, 2002 - New drop: DEVELOPMENT FOX 1.1.15
 |
- Changed internal representation of FXString; the end-of-string character ('\0') is no longer special and all possible bytes are now allowed.
- Added new API's to FXString:
- length(int) changes the length of the string buffer to the given size.
- section() extracts num segments starting from start from a string delimited by delim.
- simplify() simplifies white-space in string.
- before() returns characters before n-th occurrence of ch, starting from begin.
- rbefore() returns characters before n-th occurrence of ch, starting from end.
- after() returns characters after n-th occurrence of ch, starting from begin.
- rafter() returns characters after n-th occurrence of ch, starting from end.
- find() searches for character, starting from begin.
- rfind() searches for character, starting from end.
- find() searches for n-th occurrence of character, starting from begin.
- rfind() searches for n-th occurrence of character, starting from end.
- find_first_of() searches for first character in a set, starting from begin.
- find_last_of() searches for first character in a set, starting from end.
- find_first_not_of() searches for first character NOT in a set, starting from begin.
- find_last_not_of() searches for first character NOT in a set, starting from end.
- escape() returns a string where all special characters are escaped.
- unescape() returns a string where all escaped characters are turned back into special characters.
- Some API's of FXString are now removed:
- extract() is replaced by the much more flexible section().
- findf() is replaced by find().
- findb() is replaced by rfind().
- size() no longer exists.
- size(int) no longer exists.
Note that these changes give FXString an API more consistent with the standard std::string class.
- New API's to replace some old ones:
- fxparseAccel() replaces the old fxparseaccel(). The new flavor takes an FXString parameter.
- fxparseHotKey() replaces the old fxparsehotkey(). The new flavor takes an FXString parameter.
- fxfindHotKey() replaces the old fxfindhotkeyoffset(). The new flavor takes an FXString parameter. Also, the new version correctly counts when && occurs in the string.
- fxstripHotKey() replaces the old FXString::extract().
- Added a new type FXwchar. This is a wide character for UNICODE.
- Added a new class FXWString. This is currently under development, and should NOT be used at this time.
- Added a new class FXTextCodec. FXTextCodec's subclasses will provide (state-less) conversions between UNICODE and other character sets.
- Made further improvements to FXTable widget.
- Changed many API's in FOX to return const FXString& instead of FXString. This will eliminate a copy constructor in many cases, and thus speed things up a lot.
- Added option MBOX_SKIP_SKIPALL_CANCEL to FXMessageBox. Handy if the same dialog can appear for multiple errors.
- Fixed core dump bug in PathFinder. Destructor was deleting uninitialized data.
- Added help-tag to FXWindow. Each widget may now have a help tag, which is intended to be a URL for context-sensitive help for widgets and controls. Utilization of this info is currently up to the programmer.
- Reformatted some web pages for Mozilla.
- Updated some API's to FXArray and FXObjectList.
- Added more error checking into PNG and JPEG loader; a bad image file should not cause an application error anymore, but a simple error code will be returned. Also, the FXImage will be set to empty when a bad file format did not read.
- Fixed bug in FXFile (MS-Windows) in recursive copy routine.
- FXImage, FXIcon, FXBitmap have been made a bit more forgiving when size is 0x0; it no longer terminates the application but creates a 1x1 image instead.
- Changed API's loadPixels() and savePixels() of the various FXImage-derived types to return a boolean which indicates success or failure.
- FXMenuCheck widget added which will draw a check box beside the caption.
- FXWindow::destroy() and FXWindow::detach() will reset FXApp::focusWindow and FXApp::cursorWindow.
- FXDirList bug fixes:- currentitem and anchoritem were left pointing to deleted items in some cases. Also, directory scanner caused some problems in some cases due to CreateFile() holding handle while FindFirstFile() was trying to open directory for scanning.
- Sublte bug with SEL_CONFIGURE fixed:- on Windows v.s. Unix, the width and height of the widget were different while in the callback.
- Added to FAQ.
August 29, 2002 - New drop: DEVELOPMENT FOX 1.1.14
 |
Of course, all bugs found so far in the stable releases have been fixed in the development release.
- Some API's renamed in FXList, FXIconList, FXHeader, FXComboBox and FXListBox:- retrieveItem() has been renamed to getItem(), and replaceItem() has been renamed to setItem(). Its much easier to remember this way.
- FXTable button mode cells now get pressed (thanks to Alastair Growcott for the patch).
- Added assign() API's to FXString. Makes it easier to fill FXString with some text.
- Added FXMenuCheck, FXMenuRadio classes. These will subsume the FXMenuCommand for checked menus and radio menus; FXMenuCommand will just be a command.
- FXMDIClient no longer derived from FXScrollWindow. This will entail fewer problems.
- FXSeparator class added. It automatically flips based on width:height ratio.
- Added tag string to FXWindow for on-line help tagging of widgets; help systems may use this to provide context sensitive help for controls or dialogs.
August 29, 2002 - New drop: STABLE FOX 1.0.22

- A slight tweak has been implemented in FXFileList's collating functions:- instead of just sorting based on type, size, etc. it now also sorts on the name if the type, size, etc. are the same. So if you sort based on e.g. file type, then within each file type, the list is now lexicographically sorted.
- Minor bug with FXShutter widget fixed. This one shouldn't really have affected anyone.

- Finally, hardware problems over here at fox-toolkit.org seem to have been resolved! Funny thing is, we're not even overclocking! But nevertheless an Athlon in Alabama in summer on a sunward-facing room has appeared to be a real challenge!
- As of this week, there has been an addendum to the Lesser General Public Licensegoverning the distribution of FOX. The intent of the change is to make it more practical for applications to link statically against FOX; please refer to the license statement for the details.
- Minor bug in FXGLViewer fixed related to image printing.
- Minor buglet in FXTopWindow::setDecorations() fixed.
- FXDriveBox, FXDirBox suffered from uninitialized memory reads:- thanks to valgrind, we found out about this and fixed it.
- Fixed a few bugs in removeRows() and removeColumns() were inconsistent and did not properly deal with with spanning cells. Also setTableSize was fixed and now initializes cells to be empty, i.e. NULL.
- FXList, FXIconList delete items in reversed order, i.e. starting with the last item. This makes maintaining your own parallel list much easier.
- Fixed problem in FXSpinner.
- Esoteric FXFileList bug fixed (Windows) certain programs (e.g. older version of ws_ftp) set bogus file time on files, this caused FOX to crash.
July 25, 2002 - New drop: FOX 1.0.17
 |
- Fixed FXList, FXIconList, FXTable callback. When current item or current row/column is removed, SEL_CHANGED callback is generated.
- Fixed FXPopup menu behavior under Windows.
- Added preliminary support for Digital Mars C++ compiler.
- FXFileList sort by modification date bug was fixed.
July 16, 2002 - New drop: FOX 1.0.15
 |
- Some patches for Digital Mars C++.
- Only update widgets of new color setting is different from old.
- FXTabItem was using the wrong code to draw itself.
- File time problem retro-ported from development version.
July 1, 2002 - New drop: FOX 1.1.13
 |
- Patch from Janusz Ganczarski to add support for 16bpp BMP format files.
- Another patch from Janusz to add support for 32 bit BMP format, as well as some bug fixes to the TARGA image format support.
- Made FXMDIChild draw nicer, by adding interior sunken border.
- Added API's to FXMDIClient for various window placement manipulations.
- Fixed FXMDIClient no loner derives from FXScrollArea. This allows opaque dragging of FXMDIChild windows.
- Adding a FXRuler widget. Ruler widget may be used to place tickmarks and numbers around another widget, for example drawing document; this one will still need lots of work.
July 1, 2002 - New drop: FOX 1.0.14
 |
- BMP i/o support for 16, and 32 bit, in addition to already implemented 1, 4, 8, and 24 bit BMP images was added.
- Potential infinite loop in FXImage::restore() was fixed.
- In FXMatrix, getNumRows() and getNumColumns() should not depend on child's visibility.
- FXTable: colors should default to normal back color.
June 19, 2002 - New drop: FOX 1.1.12
 |
- Added FXWizard class, and new wizard demo application.
- Added fxparsegeometry() function to parse string of the form: "[=][{xX}][{+-}{+-}]" Into a width, height, x, and y value.
- Fixed FXProgressBar to be flicker-free when setProgress() is called repeatedly; this is done by directly drawing it in the setProgress() call.
- Added a new widget, FXImageFrame, which may be used for simple rendering of images.
- Split the Adie text editor into multiple top-level windows. This allows a single editor to open any number of documents at the same time. Adie is UNDER CONSTRUCTION right now and NOT FULLY FUNCTIONAL!!
- Added setCancelled() API to FXProgressDialog.
- Added maximize(), minimize(), restore() API's to FXTopWindow. Also added isMaximized(), and isMinimized() API's. The old iconify() and deiconify() has been superceeded by these new API's. The new API's are implemented in terms of the new Extended Window Manager Hints standard.
- New API close() added to FXTopWindow added to close a top level window. The close() API will only close the window after consulting the FXTopWindow's target, if any, whether it is OK to do so. When there is no objection, the FXTopWindow will be deleted. When the last FXMainWindow is closed, the application will receive an ID_QUIT message.
- Polarity of SEL_CLOSED message return value has changed; returning 0 means "no objection" i.e. proceed with the closing. Rationale:- when there is no target, or when the widget's target does not respond, closing the window should proceeed.
- Added drawing a chord arc fill drawing method to FXDCWindow. This augments the pie sector method already present.
- Added polygon region constructor to FXRegion.
- Fixed some idiosyncracies in FXText. When typing to replace a selection with new text, two callbacks, instead of one, were being generated. This implied that a single action needed two undo's to undo it.
- Also fixed was a little quirk that happened when a paste was being performed inside an existing selection. This is now blocked.
- FXTopWindow's now appear where they're supposed to, at least on ICCCM compliant Window Managers; borders are discounted as far as placement of window is concerned.
- A new API isOwnerOf() added to FXWindow which is used inside FXApp to determine whether events are passed to a window or not. The upshot is that modal dialogs can now create non-modal subwindows, and thus events are passed to all windows owned (and ownership is transitive!!) by the modal window, and blocked elsewhere.
- Fixed various focus sublteties, and simplified focus assignment code. The subtleties are for example the assignment of the focus to a child window of a composite, when the focus were to move to the composite. This is useful for mega widgets which need to force the focus on a specific child window when they get the focus.
- Added golden ratio constant in FOX Calculator.
May 12, 2002 - New drop: FOX 1.1.9
 |
- New FXGradientBar widget is now ready for business! Allows for drag and drop of colors, various color blending features ranging from linear to quadratic, and furthermore horizonal or vertical orientation.
- FXDict, FXMetaClass now deploy a faster, in-lined hashing function. This should translate into slightly faster application startup times.
- Various API's to FXWindow turned into "const" members.
- New API getTempDirectory() added to FXFile.
- FXFileList worked oddly if weird file mod time was found.
- Memory leaks fixed, thanks to valgrind.
- Tentatively added FXGzStream and FXBzStream classes for gzip and bzip2 compressed I/O streaming support.
- FXApp now remembers original display variable passed in. This can be used for later opening of display.
April 5, 2002 - New drop: FOX 1.1.8
 |
- New widget, FXGradientBar, which is used to build color gradient ramps (e.g. for OpenGL texturing...).
- Removed limitation of single FXMainWindow; this means the API FXApp::getMainWindow() has now disappeared. When the last FXMainWindow is closed, the application ID_QUIT is invoked, terminatin the application.
- Behaviour of middle mouse paste in FXText was simplified; this makes a paste of a selection work properly, even if the paste occurs in or near the current selection!
- Introduced name spaces. All FOX API's are now in the namespace "FX", thus the vast number of possible identifier clashes are now avoided; note that a great number of #define's have now been replaced by enum's.
- Renamed FXApp::getRoot() to FXApp::getRootWindow() for consistency.
- Renamed a number of widgets. Various widgets have over the course of time gotten names which did not adhered to the current nomenclature; this made them more difficult to memorize. These widgets have now been renamed for greater consistency:
- FXTooltip becomes FXToolTip
- FXToolbar becomes FXToolBar
- FXScrollbar becomes FXScrollBar
- FXMenubar becomes FXMenuBar
- FXStatusbar becomes FXStatusBar
- FXStatusline becomes FXStatusLine
- FXToolbarShell becomes FXToolBarShell
- FXToolbarGrip becomes FXToolBarGrip
- FXProgressBar becomes FXProgressBar
February 26, 2002 - New drop: FOX 1.0.0
 |
- Yes, I went to 1.0!!! Why not? The code has been *very* stable for a while, and its time we called it what it is:- the 1.0 release!
- New API's to FXString. FXString::vscan() and FXString::scan() are API's to parse a string via sscanf-style format conventions. This is very useful in many cases, and obviates the need for some complex coding in the past.
- New API's to FXRegistry (actually, FXSettings). FXSettings::readFormatEntry() and FXSettings::writeFormatEntry() perform sscanf- and sprintf-style access to registry database strings. As with FXString, this obviates the need for complex coding and is very compact and convenient.
- Removed deprecated functions from fxdefs.h. The following functions have been removed: fxprefix(), fxsuffix(), fxexpand(), fxpathname(), fxdirpart(), fxfiletitle(), fxfilepart(), fxfileext(), fxexists(), fxisdir(), fxisfile(), fxbakname(), fxidentical(), fxsplit(), fxshortestpath(), fxupdir(), fxabspath(), fxistopdir(), fxgetcurrentdir(), fxmkdir(), fxgethomedir(), fxsearchpath(). These functions have been moved to the file: fxdeprecated.h and fxdeprecated.cpp. Should your application need them, simply include these two files into your project. Note, the functions above have better maintained, and easier-to-use equivalents in the FXFile namespace.
- A new file, vsscanf.cpp, was added for those systems where vsscanf() and its ilk are not available. Under Linux, and other C99 standard compliant C Libraries, this file is not used.
- Added some missing API's to FXListBox, FXComboBox, and FXTreeListBox; simplified internals of these widgets a bit.
- Fixed some FXDirBox problems; removed reliance on deprecated API's.
- Added a SELECTFILE_MULTIPLE_ALL to FXFileSelector (and FXFileDialog). This mode allows selection of a mix of files and directories. The mode SELECTFILE_MULTIPLE works as before, and selects only multiple, existing filename names (and no directories).
- Fixed FXPopup focus navigation:- hidden menu items should not be focused upon.
- Fixed little biddy problem in FXText and style settings.
- Fixed text in FXReplaceDialog and FXSearchDialog; was not proper.
- Fixed little problem in FXRex::substitute().
- Fixed some minor configure issues. You can pass overrides for JPEGLIB, PNGLIB, TIFFLIB, ZLIB, and MATHLIB. This is useful if you want to force a different library than the one found in the usual places (for example if you loaded a newer version than your system came with, or want to force static linking, etc.). Also added a test to search for vsscanf() function in your C library.
- Added quick-and-dirty, ad-hoc, "hack" to Adie for syntax coloring. It still piggy-backs on the timer. However, the dialogs to set up highlight styles, language recognition, and syntax patterns is essentially complete. You can now add and remove, and edit syntax patterns fairly reliably. I added a sample C++ and C syntax file you can drop into your .foxrc/Adie registry (or in any of the usual global registry places /usr/lib/foxrc/Adie, /usr/local/lib/foxrc/Adie, etc.) to kick-start some patterns to get you started. The stylizer can now also use patterns with back-references, or capturing parentheses; I will still figure some way to color captured parentheses some day as well.
- WANTED: syntax patterns for various languages: PERL, RUBY, PYTHON, HTML, XML, Pascal, Eiffel, and whatever else you can think of. I will collect these patterns and distribute them in future versions of Adie.
February 5, 2002 - New drop: FOX 0.99.193

- Added new mode SWITCHER_HCOLLAPSE and SWITCHER_VCOLLAPSE to FXSwitcher; these will cause the FXSwitcher to collapse its default height or width to the currently active child's height or width, respectively.
- Fixed bug in FXDriveBox. The option to report errors went away as FXDriveBox does not set the current drive anymore:- it just sends a message.
- Fixed declaration in FXStringDict API: API's yield const strings.
- Added support for SGI IRIS RGB Image input and output, as well as corresponding image and icon classes.
- Completed editing of style-entries in Adie (language mode and pattern panels not complete yet). Minor style-coloring engine improvements.
- Incorporated documentation man-page for Adie, PathFinder, and Calculator.
- Fixed bug in FXText::changeStyle.
- Added missing API's to FXListBox, FXTreeListBox, FXComboBox.
- Fixed grooved border drawing.
- Relaxed syntax of section and group name in FXSettings database [was too strict earlier for no good reason].
- FXWindow issues SEL_MOTION events.
- FXRex properly observes REX_NEWLINE for \D, \s, \W, and so on.
January 8, 2002 - New drop: FOX 0.99.189

- Optional style buffer was added. FXText takes roughly same amount of memory/text, unless style buffer is turned on in which case memory usage doubles to store the style information.
- Style table support was added. You can specify up to 127 different styles, where a style is a combination of fg/bg colors for normal, selected, or highlighted display, i.e. 6 different colors.
- New API's added to manipulate contents of the style buffer. First, normal API's like appendText() and so on now have an equivalent appendStyledText(). The style is a single value 0-127 indexing into style table, to which 128 may be added to achieve underlining. This makes it very easy to add colorful text....
- Its still possible I will add flags to the style table for underlining instead of use a bit in the style buffer; I don't know yet...
- changeStyle() changes the style w/o affecting the text.
- Despite the style additions, drawing has actually been speeded up quite a bit, as some old crap has been removed:
- drawing is split into painting the background and painting the text over it. This may alleviate some problems on SGI with XDrawImageString.
- drawing no longer loops over virtual characters, it just rect-fills the tail-end of a line; this is of course much faster.
- even better, drawing also accumulates runs of spaces and tabs into a single rect-fill; needless to say that is also much faster.
- FXText now maintains a c&
