Incompatible Changes from GTK+-1.0 to GTK+-1.2:
* GtkAcceleratorTable has been replaced with GtkAccelGroup
* GtkMenuFactory has been replaced with GtkItemFactory, although
a version of GtkMenuFactory is provided to ease compatibility.
* GtkButton has been changed to derive from GtkBin.
To access a button's child, use GTK_BIN (button)->child, instead
of the old GTK_BUTTON (button)->child.
* The selection API has been slightly modified:
gtk_selection_add_handler() and gtk_selection_add_handler_full()
have been removed. To supply the selection, one now register
the targets one is interested in with:
void gtk_selection_add_target (GtkWidget *widget,
GdkAtom selection,
GdkAtom target,
guint info);
or:
void gtk_selection_add_targets (GtkWidget *widget,
GdkAtom selection,
GtkTargetEntry *targets,
guint ntargets);
When a request for a selection is received, the new "selection_get"
signal will be called:
void "selection_get" (GtkWidget *widget,
GtkSelectionData *selection_data,
guint info,
guint time);
A "time" parameter has also been added to the "selection_received"
signal.
void "selection_received" (GtkWidget *widget,
GtkSelectionData *selection_data,
guint time);
* The old drag and drop API has been completely removed and replaced.
See the reference documentation for details on the new API.
* Support for Themes has been added. In general, this does
not affect application code, however, a few new rules should
be observed:
- To set a shape for a window, you must use
gtk_widget_shape_combine_mask() instead of
gdk_window_shape_combine_mask(), or the shape will be
reset when switching themes.
- It is no longer permissable to draw directly on an arbitrary
widget, or to set an arbitrary widget's background pixmap.
If you need to do that, use a GtkDrawingArea or (for a
toplevel) the new GtkDrawWindow widget.
