Two warts remain. gdk_event_copy() should be unnecessary as
events should be considered static after delivery, so g_object_ref()
should be just as good. There's a few exceptional cases that the event
is copied and then modifier for later processing, those cases should be
reconsidered individually.
And gdk_event_free() could be likewise turned into g_object_unref(),
many callers remain though.
Now all events structs are private, it doesn't make as much sense
having GdkEventPrivate wrapping allocating events. This is a first
step towards removing it.
It won't stand true anymore that the GdkEventType argument is the
first field of the GdkEvent* structs. All callers have been updated
to use event->any.type instead.
Scrolling a path bar is of marginal usefulness - you need to
find a really deep place in your filesystem hierarchy in order
to scroll one or two places at best. And the code we had for
this was not working. And it was using legacy event handlers.
Instead of fixing it, remove it.
We now have a GdkX11Display::xevent signal that gets emitted for every
XEvent and allows you to interrupt processing via TRUE/FALSE return
values.
These return values to correspond to GDK_FILTER_REMOVE and
GDK_FILTER_CONTINUE respectively.
The GDK_FILTER_TRANSLATE case from gdk_window_add_filter() is now meant
to be handled via gdk_display_put_event().
This is in preparation for DND.
It moves a lot of code from gdkclipboard-x11.c to
gdkselectionoutputstream-x11.c to untangle it from GdkX11Clipboard
usage.
This code was doing horrible things, and the atk documentation
for the focus tracking feature says that this is deprecated and
not used anymore. So lets not do it.
Mark the following signals as deprecated:
event, event-after, button-press-event, button-release-event,
touch-event, scroll-event, motion-notify-event, enter-notify-event,
leave-notify-event, property-notify-event, selection-clear-event,
selection-request-event, selection-notify-event, selection-received,
selection-get, proximity-in-event, proximity-out-event. Most
of these have suitable replacements in event controllers and
gestures already. The selection-related signals will soon be
irrelevant when selection handling moves to GDK.
Set G_ENABLE_DIAGNOSTIC=1 to see deprecation
warnings for uses of these signals.
Instead, pass the actions as part of gdk_drag_begin() and insist DND is
always managed.
A new side effect is that gdk_drag_begin() can now return %NULL.
