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.
|
|
|
|
* Scrolled windows do not create an automatic viewport anymore, and
|
|
self scrolling widgets do not provide their own scrollbars any
|
|
further. Self scrolling widgets of the Gtk+ core currently are
|
|
GtkViewport, GtkCList, GtkCTree, GtkText and GtkLayout. All of
|
|
these widgets can be added to a scrolled window as normal children
|
|
with gtk_container_add() and their scrolling abilities will be setup
|
|
appropriatedly in an automatic manner.
|
|
Widgets that do not implement own scrolling abilities but get added
|
|
to a scrolled window in order to have their allocations scrollable
|
|
inside of the scrolled window (e.g. a GtkList) have first to be added
|
|
to a GtkViewport, and then the viewport needs to be added to the
|
|
scrolled window.
|
|
However, the scrolled window code provides a convenience function to
|
|
achive this:
|
|
gtk_scrolled_window_add_with_viewport() which will do exactly what
|
|
it says, add a child widget to a viewport and put that viewport into
|
|
the scrolled window.
|
|
Scrollbar policy adjustment needs to be perfomed on the scrolled window
|
|
with gtk_scrolled_window_set_policy() and is not longer maintained for
|
|
the child widgets (e.g. GtkCList's gtk_clist_set_policy() got removed).
