This was the last exported variable; it wasn't multihead safe,
and there's easy replacement with gdk_display_get_default().
Also drop the GDK_DISPLAY() macro which was just a wrapper around
the variable.
gtk_widget_set_window() does not add a reference to the
owned window... this is an exception to most gtk_foo_set_bar()
functions where as it acts as if it were named gtk_widget_take_window().
Adding note to the docs to avoid people giving the window to the
widget and naturally proceeding to unref the window.
Fixed issues in my previous patch for bug 626939 removing GtkRequisition
cache: these widgets monitor the previous requested size and decide whether
to queue a resize when the content changes based on it's prior request.
Now that we have a private data installed directly on
the GtkWidget instance it makes no sense to cache the size
requests on widget qdata. This change will generally make
GTK+ memory less fragmented as well as significantly speed
up the size request process.
Rename the gtk_major_version() etc functions I introduced yesterday to
start with gtk_get. Avoids misleading results in client programs whose
developers that don't notice the change or the compiler warnings, and
when recompiling against gtk3 then use the function addresses as the
version numbers.
With the demise of GtkList and GtkTree, it has GtkMenuItem as sole
derived class, and is not really adding any value as a separate class.
Its few useful features have been merged into GtkMenuItem.
Bug 629104
The keysyms create a lot of potential namespace conflicts for
C, and are especially problematic for introspection, where we take
constants into the namespace, so GDK_Display conflicts with GdkDisplay.
For C application compatiblity, add gdkkeysyms-compat.h which uses
the old names.
Just one user in GTK+ continues to use gdkkeysyms-compat.h, which is
the gtkimcontextsimple.c, since porting that requires porting more
custom Perl code.
Especially the gtk_*_type ones in gtktexttypes.h were mentioned in
gtk.symbols presumably by accident. That header isn't even installed,
so no way can they be supposed to be public.
gtk_text_attr_appearance_type is from the installed but "semi-private"
gtktextlayout.h, so drop that one too from gtk.symbols for now.
The use of gtk_text_unknown_char_utf8 is bit of a mess. Code in a few
files knew implicitly that it is three bytes. Define a symbolic name
for the length of it instead. Add an exported function
gtk_text_unknown_char_utf8_gtk_tests_only() that returns a pointer to
it just for the sake of gtk/tests/textbuffer.c. Prefix the variable
with an underscore.
I doubt the usefulness of the test_utf8() in textbuffer.c. If it could
be dropped, gtk_text_unknown_char_utf8_gtk_tests_only() could be
dropped, too.
Preferrably should be made just into a local variable for libgtk like
_gdk_debug_flags for libgdk. But for now used by
gtk/tests/textbuffer.c and modules/printbackends/cups/gtkprintbackendcups.c.
