Moving the direct-access redefinitions of various macros
to gdkprivate-x11.h and use that header throughout in x11/.
Also remove a workaround for a long-fixed X server bug.
The X11 backend exports a number of symbols which are _-prefixed
(so don't become part of the gdk api), but are not named in a
way to prevent accidental clashes between backends.
The one API change here is that the gdk_xid_table functions
have been removed - they did not server an purpose, since the
xid table only stores windows anyway, and we already have a
lookup-by-xid function for windows.
It turned out no vfuncs were necessary. I've decided to move
the screen member up to GdkVisual, since it is the same in all
backends. The X11 backend subclasses now, to add the X members
that it needs to keep track of. GdkVisual and GdkVisualClass
are hidden now.
This way, we can specify a colormap when constructing windows. And ew
must do that to avoid BadMatch from XCreateWindow when we use a
different visual.
Also add a priv pointer to GdkVisual and use it for the GdkVisualPrivate
structure. Then Make GdkVisualPrivate actually private to
gdkvisual-x11.c and make other callers use proper function calls to
access it.
The Gdk-custom.c file in gir-repository contained a number of
introspection annotations. Merge those into the GDK source files.
Some documentation was moved from the tmpl/ files to accomodate
the addition of annotations.

Either g_type_register_static_simple (used by G_DEFINE_TYPE_EXTENDED)
and G_IMPLEMENT_INTERFACE use automatic variables for GTypeInfo and
GInterfaceInfo structs, while tutorials and source code often use
static variables. This commit consistently adopts the former method.

* gdk/x11/gdkvisual-x11.c (_gdk_visual_init):
Initialise nxvisuals to 0 in order to handle
XGetVisualInfo() failures gracefully. (#419171)
svn path=/trunk/; revision=17538
2005-11-10 Michael Natterer <mitch@imendio.com>
Applied patch from maemo-gtk that addresses many issues wrt
display migration and display closing (bug #85715).
* gdk/gdkdisplay.c (gdk_display_dispose): don't just set the
default display to NULL when it's closed. Instead set the most
recently opened display as new default (if one exists).
* gdk/gdkpango.c (on_renderer_display_closed): fixed signature
of this callback.
* gdk/gdkscreen.c (gdk_screen_dispose): check if the GCs still
exist before unrefing them.
* gdk/gdkwindow.c (_gdk_window_destroy_hierarchy): if the screen
is closed, allow destruction of the root window.
* gdk/x11/gdkdisplay-x11.c: moved some stuff from finalize() to
dispose(), free stuff that was leaked before.
* gdk/x11/gdkevents-x11.c (_gdk_x11_events_uninit_screen): check if
the xsettings_client still exists before destroying it.
* gdk/x11/gdkkeys-x11.c: added finalization and free the allocated
X resources.
* gdk/x11/gdkpixmap-x11.c: moved stuff from finalize() to new
dispose() implementation.
* gdk/x11/gdkscreen-x11.c: moved stuff from finalize() to
dispose() and check if it still exists before unrefing it. Set
their pointers to NULL/None *after* upchaining in dispose(),
because X11 implementations of members of the parent class still
need them for their own destruction.
* gdk/x11/gdkvisual-x11.c: removed finalize() implementation which
was g_error()ing when finalizing a visual.
* gtk/gtkclipboard.c (gtk_clipboard_finalize): don't use
get_clipboard_widget() because it would create the widget if it
doesn't exist. Use g_object_get_data() directly instead.
* gtk/gtktextdisplay.c (on_renderer_display_closed): fixed signature
of this callback.
2005-06-30 Matthias Clasen <mclasen@redhat.com>
* gdk/x11/gdkvisual-x11.c (gdk_visual_decompose_mask): Avoid
infinite loop if a mask is zero. (#309222, David Saxton)
2005-05-09 Owen Taylor <otaylor@redhat.com>
* gdk/gdkrgb.c (gdk_rgb_convert_0888_br, gdk_rgb_convert_8880_br):
Fill in unused bits so they can be used for the depth-32 target case.
Rewrite so that that gives a marginal speedup rather than a
marginal slowdown. (on x86)
* gdk/gdkscreen.h gdk/x11/gdkscreen-x11.[ch] gdk/x11/gdkvisual-x11.c:
Add gdk_screen_get_rgba_colormap/visual to get a visual for
windows with an alpha channel, if one exists.
* gdk/win32/gdkscreen-win32.c gdk/linux-fb/gdkscreen-fb.c:
Stub out gdk_screen_get_rgba_colormap/visual.
* gdk/x11/gdkcolor-x11.c (gdk_colormap_alloc_colors): computation of
"unused" wasn't right for depth == 32, since it depended on
shifting by 32.
* gdk/gdkrgb.c: Fill in alpha bits with 1s. (Based on patch from
Keith Packard,
http://mail.gnome.org/archives/gtk-devel-list/2004-June/msg00080.html)
* gdk/x11/gdkdrawable-x11.c (gdk_x11_drawable_get_picture):
Implement again, without using Xft.
* tests/testgtk.c: Add a test for windows with an alpha channel.

headers, include gdkaliasdef.c at the bottom.
Mon Aug 9 15:41:17 2004 Matthias Clasen <maclas@gmx.de>
Add hidden aliases for exported symbols which are
used internally in order to get rid of many PLT
entries. (#145519, Arjan van de Ven)
* gdk/Makefile.am: Add rules to generate gdk.def and
gdkalias.h from gdk.symbols, and make make check check
the abi with abicheck.sh.
* gdk/gdk.symbols: New file. Definition of the GDK ABI.
The file can be processed by cpp to filter out certain
subsets of symbols.
* gdk/abicheck.sh: New file. Script to check the actually
symbols exported from libgdk-x11.2.0.so against the symbols
found in gdk.symbols.
* gdk/makegdkalias.pl: New file. Perl script to generate the
header containing the alias definitions for internally used
exported symbols from a list of symbols.
* gdk/*.c, gdk/x11/*.c: Include gdkalias.h

Mon Nov 8 14:47:04 1999 Owen Taylor <otaylor@redhat.com>
Move all X specific code into the x11/ directory.
Aside from shuffling things around, did the following:
* gdk/gdkprivate.h gdk/gdk.h gdk/x11/gdkmain-x11.h: Add
gdk_arg_context_* - a simple argument parsing system
in the style of popt.
* gdk/gdkdrawable.[ch] gdk/gdkprivate.h gdk/gdkwindow.[ch]
gdk/x11/gdkprivate-x11.h:
Remove X specific stuff from GdkDrawable and GdkWindowPrivate -
add ->klass and ->klass_data fields. The klass_data
field points to an auxilliary structure that is
windowing system dependent.
* gdk/gdkfont.c: Make most of the measurement functions
simply wrappers around gdk_text_extents().
* gdk/gdkfont.c gdk/gdkprivate.h gdk/x11/gdkfont-x11.c: Add a
_gdk_font_strlen() function that hides the weird
behavior in gtk+-1.[02] where a string is interpreted
differently for 8-bit and 16-bit fonts.
* gdk/gdkevents.c: Add a new function gdk_event_button_generate()
to store common code for synthesizing double/triple
press events.
* gdk/gdkgc.[ch]: Virtualize in the same way as gdkdrawable.h.
Make all the function that modify an existing GC
simply wrappers around gdk_gc_set_values().
* gdk/gdkcc.[ch]: Moved into x11/ directory in preparation
for throwing out later.
* gdk/gdkfont.c gdk/gdkimage.c gdk/gdkcolor.c: Change GdkFontPrivate,
GdkImagePrivate and GdkColormapPrivate to have a
windowing system dependent part (GdkFontPrivateX etc.)
that "derives" from the system-independent part.
* configure.in gdk/x11/Makefile.in gdk/x11/gdkinput*.c:
Got rid of the included-source-files for XInput in
favor of automake conditionals. (Which didn't exist
when XInput support was originally added.)
* gdk/gdkrgb.c: Remove the visual id from the debugging
statements since that is X11 specific; print out
type/depth info instead.
Fri Oct 1 18:03:36 1999 Owen Taylor <otaylor@redhat.com>
* docs/Changes-1.4.txt: Started
