|
|
GTK+ now includes an OpenGL rendering widget. To support GL on various
|
|
platforms, GTK+ uses libepoxy.
|
|
</p>
|
|
<p>
|
|
GTK+ no longer uses gtk-update-icon-cache during its build. The
|
|
--enable-gtk2-dependency configure option has been removed.
|
|
</p>
|
|
<p>
|
|
The introspection annotations for the x and y parameters of
|
|
GtkMenuPositionFunc have been corrected from 'out' to 'inout'.
|
|
If you are using such a function from language-bindings, this
|
|
may require adjustments.
|
|
</p>
|
|
<p>
|
|
The lookup order for actions that are activated via keyboard
|
|
accelerators has been changed to start at the currently focused
|
|
widget. If your application is making use fo nested action groups
|
|
via gtk_widget_insert_action_group, you may want to check that
|
|
this change does not upset your accelerators.
|
|
</p>
|
|
<p>
|
|
The GtkScrollable interface has gained a new vfunc, get_border,
|
|
that is used to position overshoot and undershoot indications that
|
|
are drawn over the content by GtkScrolledWindow. Unless your scrollable
|
|
has non-scrolling parts similar to treeview headers, there is no need
|
|
to implement this vfunc.
|
|
</p>
|
|
<p>
|
|
The GtkSearchEntry widget has gained a number of new signals that
|
|
are emitted when certain key sequences are seen. In particular, it
|
|
now handles the Escape key and emits ::stop-search. Applications that
|
|
expect to handle Escape themselves will need to be updated.
