The function returns the part of a monitors area that should be
used for positioning popups, menus, etc. The only non-trivial
implementation atm is in the X backend, all the other backends
just return the full monitor area. The X implementation is
currently suboptimal, since it requires roundtrips to collect
the necessary information. It should be changed to monitor
the properties for changes, when XFixes allows to monitor
individual properties.

This turns GdkWin32DragContext into a proper GdkDragContext subclass.
Because we now correctly initialize GdkWin32DragContext in
gdk_drag_context_new, we no longer crash immediatly when a DnD
operation is initialized (the find_window, drag_status, ... vfuncs
where all pointing to 0x0 instead of their proper win32 implementations).
We now try to consistently refer to GdkDragContext as "context",
GdkWin32DragContext as "win32_context" and the ole2 related
target_drag_context and source_drag_context as "ctx".
Members of GdkWin32DragContext only used by the ole2 DnD codepaths
are now explicitly marked with a ole2_dnd_ prefix.
We now do proper handling of existing invalid regions, and
we use ScrollDC which allows us to specify the right clip
region rather than just the bounding rect.
Positioning windows at 0,0 post creation failed, because it
was mapped with CW_USEDFAULT, but private->x/y still said 0,
so moving it to 0,0 did nothing. We now always position the
window at the right place, even when not mapped, but we
create it at CW_USEDEFAULT initially and store that position
before moving it to the right place.
This fixes the window sizing test in testgtk and the inital
position for the gimp toolbar.
The synaptics trackpad driver has some weird behaviour on scroll.
It pops up a window over the mouse pointer (looking like a scrollbar).
This has two problems:
* We get extra enter/leave events for the trackpad window
* We get back the trackpad window when we look for the window
under the mouse to deliver the mousewheel message.
So, we add some trackpad specific hacks to avoid this (sigh) based
on the trackpad window window class.
This fixes bug #542777 and was partially based on a patch there
from Peter Clifton.
gdk_flush() should gdk_display_sync() on all open displays.
Both for display_flush and display_sync it seems useful to call
GdiFlush, but we don't have anything extra to do for display_sync,
as there is no inherent roundtrip on win32.
This should close bug #84314
Windows with transients: center on parent
Splash screens: center on monitor
Also properly ignores initial moves of unmapped
windows that are not override redirect or HINT_POS
Fixes bugs #324254 and #612359
There were still cases where we didn't get a WINDOWPOSCHANGED after
a SetWindowPos() call, like e.g. with a larger minimum size than
the set size (bug #574935)
So, we revert the previous fix and now just always manually emit
a configure notify after the move_resize call. Also, we inhibit
the WINDOWPOSCHANGED configure event during the move_resize operation
to avoid multiple Configures.
There are some cases where we don't get a WINDOWPOSCHANGE such that
we generate a configure event, even if we called gdk_window_move_resize()
or similar. For instance:
* The window is fullscreen
* The window is maximized
* The specified pos/size is the same as the current one
However, as per X11 ConfigureNotify semantics we *always* want one, or
we could run into issue like e.g. bug #537296 where we're waiting for
the CONFIGURE to call gdk_window_thaw_toplevel_updates_libgtk_only().
We always get the WM_DESTROY message anyway, and we remove it there.
Bug #336416 even claims this could be a leak if the WM_DESTROY
message was not seen before the DestroyWindow call returned, as
the WM_DESTROY message could not be handled later without the
window in the handle table. I'm not sure this can happen, but we
might as well remove it.
There is no particular reason to special case this, we want to handle all
sort of normal events. The only special thing we keep is that
as an optimization we pump the message loop extra during a WINPOSCHANGED
in a modal operation as that will cause us to repaint faster.
Also, bump the arbitrary number of mainloop iterations for the timer.
I don't see why we need it at all, but at least doing more than one
iteration if needed should be nice.
When you start a window resize or move via the window menu and
don't actually change anything we're not getting an exitsizemove.
In order to work around this we also look for WM_CAPTURECHANGED.
This moves all the code from WM_SIZE, WM_MOVE, and WM_SHOWWINDOW into
one place, cleans up the code and makes sure we only send a single
configure event even if both size and position changes.
We don't pass in raise anymore, but already_mapped.
Also, already_mapped must be used rather than MAPPED, as we already
synthesize the MAPPED in the generic code (and thus we don't have
to synthesize it again).
Calling PeekMessage can cause reentrant calls into the window procedure
for sent (as opposed to posted) messages, so its not safe to call
when we're not expecting reentrancy. Instead we call GetQueueStatus
when we're just looking for availible messages.

By reverting gdk_drag_find_window_for_screen logic to what it was
before eb21a7df29.
The old logic knew how to ignore drag_window when searching
for dest_window, but that code was removed (I guess by accident).

Commit 5ebb32d1ff didn't add the correct
code to find the toplevel window. The WindowFromPoint() function does
not return the toplevel window in the hierarchy, it returns the deepest
non-disabled, non-invisible child. As we don't use invisible or disabled
windows, we don't actually need to use the ChildWindowFromPoint walk for
the non get_toplevel case, so we can remove that code path.
To find a toplevel, we need to start from the desktop and work up, using
ChildWindowFromPointEx (to ignore invisible and disabled windows). If we
don't ignore invisible and disabled windows (as is the case with the
ChildWindowFromPoint call, we are liable to get returns of hidden or
disabled children of the desktop which don't belong to us, but notionally
occupy the same area under the pointer.
An alternative might be to start our walk with one of the children of the
desktop owned by our process and thread - which we can enumerate using,
the EnumThreadWindows call, or (presumably) determine internally. This
would not work when we are inside a GtkSocket though, as the children of
the desktop would belong to the process owning the GtkPlug - we would
have to rely on our own list of windows.
For correctness, this commit adds tests to ensure that we don't try to
return either x or y window coordinates if that corresponding pointer is
NULL.

The button highlighting in testgtk works again, even with
GDK_NATIVE_WINDOWS. Unfortunately testgtk:menus still does
not work for the forced-native-window-case.
In _gdk_window_move_resize_child it tries to decide whether to pass
SWP_NOSIZE and SWP_NOMOVE based on whether the new size and position
is different from the window's existing position. However it seems
that GDK now ends up updating the window's position before calling
_gdk_window_move_resize_child so this would mean it would think the
window never changes size or position so SWP_NOSIZE|SWP_NOMOVE would
always be set. This causes child windows to never be resized.
This patch changes it so that it never passes either flag to
SetWindowPos. I don't know whether this will cause any side effects
but you'd think it shouldn't do any harm to reassert the current size.
