GdaGraphItemGdaGraphItem — Parts of data model used with the GdaGraph object. |
GObject * | gda_graph_item_new () |
void | gda_graph_item_set_position () |
void | gda_graph_item_get_position () |
GdaObject * | gda_graph_item_get_ref_object () |
Each graph item which needs to have its position kept in the GdaDict object (and written in the dictionary file) has a corresponding GdaGraphItem object. A graph item can hold a reference to any GdaObject object, meaning that the position it stores is the position where the references object's graphical representation will be on the canvas.
GObject * gda_graph_item_new (GdaDict *dict
,GdaObject *ref_obj
);
Creates a new GdaGraphItem object
void gda_graph_item_set_position (GdaGraphItem *item
,gdouble x
,gdouble y
);
Sets the position to be remembered for item
.
void gda_graph_item_get_position (GdaGraphItem *item
,gdouble *x
,gdouble *y
);
Get item
's position.
GdaObject *
gda_graph_item_get_ref_object (GdaGraphItem *item
);
Get the referenced GdaObject object, if it exists.
