This commit hides GdkDragContext and GdkDragContextClass, adds
vfuncs for most drag context functionality, and turns the X11 DND
implementation into GdkDragContextX11. We also add vfuncs to
GdkDisplay for gdk_drag_get_protocol and to GdkWindow for
gdk_drag_begin, and implemenet them for X11.
Other backends need similar treatment and are broken now.
Add a GdkDisplay::get_app_launch_context vfunc, and a
gdk_display_get_app_launch_context that for X11 returns a subclass.
For win32 and quartz, the implementations were trivial, so we
just return a new GdkAppLaunchContext without subclassing. Since
the type of the context now depends on the display,
gdk_app_launch_context_set_display is deprecated.
One less magic function. Also refactored it to make it easier to
implement. It now returns TRUE if it beeped and FALSE if it failed to do
so. A default implementation exists that just returns FALSE for all the
backends that can't beep windows (read: everything but X11 with XKB -
and why on earth do keyboard libs implement beeping?)
Trying to get rid of all the _gdk_windowing_something() functions that
we expect backends to magically know about and instead put them in a
proper interface (mostly GdkWindowImplClass).
An event filter may add or remove filters itself. This patch does
two things to address this case. The first is to take a temporary
reference to the filter while it is being used. The second is
to wait until after the filter function is run before determining
the next node in the list to process. This guards against
changes to the next node. It also does not run functions
that have been marked as removed. Though I'm not sure if this
case can arise.

We subclass GdkWindowImplQuartz into a new GdkRootWindowImplQuartz,
and override the get_context method in order to do this cleanly.
Also made release_context a virtual method, since the root window has
to release its CGContextRef differently compared to normal windows.
In particular, the following functions are gone:
- gdk_screen_get_default_colormap()
- gdk_screen_set_default_colormap()
- gdk_screen_get_system_colormap()
- gdk_screen_get_rgba_colormap()
Now the window background is a cairo_pattern_t. The backends will try to
set this as good as they can on the windowing system, but no guarantees
are made on wether the windowing system supports the pattern.
Also gets rid of GDK_NO_BG as undefined behavior is not a good idea to
support, and GDK_NO_BG effectively made the window's contents undefined.
It wasn't effectively used in GTK anyway.
* add per-display gdk_x11_display_error_trap_push()
(X11-specific because gdk_error_trap_push() probably
should have been)
* make gdk_error_trap_push() handle only GDK displays
not displays opened without a GDK wrapper
* make gdk_error_trap_pop() and gdk_x11_display_error_trap_pop()
automatically sync only if needed, so manual gdk_flush() is not
required
* add gdk_error_trap_pop_ignored() which just asynchronously
ignores errors, so never needs to sync
* add G_GNUC_WARN_UNUSED_RESULT to plain pop(), because
if you use plain pop() and don't need the return value,
the async gdk_error_trap_pop_ignored() should be used
instead. This results in lots of warnings to clean
up in a later patch.
The main objective here was to avoid the need to sync just
to ignore an error. Now, syncing is automatic, and only
happens when we need to know the error code.

Mainly fixes to properly differentiate between toplevel and offscreen
windows, since these sometimes need different treatment. Furthermore,
usage of gdk_window_get_effective_foo() instead of gdk_window_get_foo()
where applicable.
While X11 surfaces can be resized, this is not the case for Quartz
surfaces. Instead of resizing we will invalidate the surface instead.
By giving _gdk_windowing_set_cairo_surface_size() a boolean return
value, we can signal back whether or not resizing was possible. If not
possible, we invalidate the surface.
The window move code needs special attention for multiple reasons:
- invalid areas for expose events need to be modified
- self-copy is not supported by Cairo
- in X11, copying from an overlapped Window might cause unexposed areas
to be copied in, spo expose events for those need to be generated.
This was all special cased in various parts of the code. By making it an
explicit vfunc, we can work around it.
Includes fixing all callers to use the cairo region API instead. This is
usually just replacing the function names, the only difference is
gdk_region_get_rectangles() being replaced by
cairo_region_num_rectangles() and cairo_region_get_rectangle() which
required a bit more work.

This function makes a better replacement for
gdk_display_get_core_pointer(), wherever it might yet be needed, for
XI2 resorts to XIGetClientPointer(), for the others return the only
core pointer.

It turns out that my attempt at handling Super, Hyper and Meta better
is causing problems, mostly because Alt and Meta are commonly colocated
in the modmap, and apps do a check for the Alt modifier regularly.
See e.g bug 607697.
On X11 we receive enter notify and motion notify events for a window
regardless of its focus state. On Mac OS X this is not the case. This
commit improves the semantics to overcome this difference. It improves
on my earlier patch that sent a motion notify event when a window became
main.
Instead of sending a motion notify when a window becomes main, we now
send one when a window becomes key, which comes closest to a window
getting focus in X11. This motion notify is needed because Mac OS X does
not send motion events when an application is inactive (none of its
windows have focus), these events are sent in X11. This dummy motion
notify event (with current coordinates of the mouse cursor) allows an
application to get its prelight and other state right when it gets focus
and thus user attention.
Another change is to send an enter notify event when updating the
tracking rectangle of a GdkQuartView and the mouse cursor is currently in
this rectangle. This rectangle is at least updated on window creation.
This enter notify event is important for the case where a new window
appears right below the mouse cursor. The window has to receive an enter
notify event for the subsequent events to be processed correctly. Mac
OS X does not send one in this case, so we generate it ourselves.
Both of these synthesized events have to go through
_gdk_windowing_got_event() for updating statekeeping, etc.
append_event() has a boolean flag now to make this convenient.
These have been introduced in Leopard and default to int and unsigned int.
In 64-bit Snow Leopard they are long and unsigned long. This caused issues
with the getRectsBeingDrawn message which needs a pointer to a NSInteger
(long on 64-bit!) but we passed in an integer. Surprisingly this problem
was visible when compiling with -O0 (segfault), but *not* when compiling
with -O1. Other messages were NSInteger is now needed have also been
adapted.
Since NSInteger and NSUInteger are not available on Tiger, a define
has been added to add typedefs for these when they have not been defined
by the system headers.
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.

We have to do this, especially after the screen containing the menubar
has changed. Such more larger changes in monitor geometry will cause
changes to how monitors are laid out in the root window. The position
coordinates of the windows will have to be updated to reflect their
position in the new layout.
The Quartz port now supports arbitrary multiple monitor layouts instead
of only monitors are were laid out horizontally. This builds on the
reworked coordinate translation done in a previous commit.
The root window contains all the monitors attached to a Mac. The
coordinate transformation now both translates the x and y coordinate,
translating it from the Cocoa monitor coordinate space to the GDK
coordinate space. How monitors are laid out in the root window differs
between Cocoa and GDK, which is why it is important to translate based
on the root window to get multi monitor setups to work properly.
We have replaced the old y coordinate transformation function with
new functions that translate both the x and y coordinate.
When creating new toplevels, we have to determine the Cocoa screen on
which the toplevel should appear and translate the coordinates according
to that screen.
This change also fixes event handling in case there is a monitor left
of the screen containing the menu bar. In such a case all coordinates
on the left monitor are negative. Event handling broke, because of
_gdk_quartz_window_find_child() checking bounds. Now that coordinates
are always properly translated to GDK coordinate space, in which negative
coordinates do never occur, the checks here will work properly.
Using this we can update our internal monitor/screen layout state
and emit the GdkScreen::size-changed signal. Work has not
completely finished on this yet, see bug 596238.
Add dummy for _gdk_input_window_crossing (). Set both input_window_destroy
and input_window_crossing pointers in the Impl struct.
Reported by John Ralls.
This has two advantages:
1) In many backends, this is faster as we can terminate the window
hierarchy traversal earlier
2) When used in gdkdisplay.c::get_current_toplevel() to get the
current toplevel that has the pointer we now correctly return
a toplevel with the pointer in it where the pointer is inside
some foreign subwindow of a toplevel window.
The second advantage fixes some bugs in client side event generation
when the pointer is inside such a foreign child window.
Based on first patches by Christian Hergert. Change
screen_get_monitor_geometry() so that it translates the layout of the screens
from Cocoa layout to GDK layout. In Cocoa, the screen locations
are specified in Cocoa geometry, as well as that GDK uses a different way
to place individual monitors in the root window. For now only monitors
that are laid out horizontally are supported (see the FIXMEs in the source),
in bug 596238 we will track future work to get things fully right.
Modify _gdk_quartz_window_get_inverted_screen_y() to take the differences
in screen layout between Cocoa and GDK into account. Also this function
is subject to future work.
Explicitly handle resizing by leaving all events in the lower right 15x15
corner to Cocoa, if the window shows a resizing indicator. Some
applications may have widgets allocated in this area. Generally, these
widgets are likely larger than 15x15 so they can still be hit. Often
scroll bars are found in this area and these can also be manipulated by
other means. Since this is the only way of resizing windows on Mac OS X,
it is too important to keep it broken.
