When we `Alt+Tab` away from a GTK application, it loses keyboard focus.
If we don't clear the modifiers, events from other devices that we
receive while unfocused will assume `Alt` is still pressed. This results
in e.g. Firefox navigating through the history instead of scrolling the
page when using the mouse wheel on it.
We don't get any information about modifiers while we are missing
keyboard focus, so assuming no modifiers are active is the best we can
do.
The shell sends us a modifier update immediately before we regain
keyboard focus, so the state shouldn't get out of sync.

Win32 backend doesn't have support for inhibit shortcuts, yet it needs
support the standard set of GdkToplevel properties.
Add support for the "inhibit-list" object property to GdkToplevel on
win32.
Broadway doesn't have support for inhibit shortcuts, yet it needs to
support the standard set of GdkToplevel properties.
Add support for the "inhibit-list" object property to GdkToplevel on
Broadway.
On X11, there is no such equivalent to the inhibit shortcut protocol
found on Wayland.
To implement the inhibit_system_shortcuts API on X11, we emulate the
same behavior using grabs on the keyboard.
To avoid keeping active grabs on the keyboard that would affect other
X11 applications even when the surface isn't focused, the X11
implementation takes care of releasing the grabs as soon as the toplevel
loses focus.
With the current implementation, we use a `wl_seat` as the key for our
internal has table where we store the Wayland shortcuts inhibitors.
There is however no technical reason for this, and we could use a
GdkSeat instead, which will ease the implementation of the GdkToplevel
shortcut inhibition API.
With the removal of grabs from the public API, we need a replacement API
to let applications bypass system keyboard shortcuts.
A typical use case for this API is remote desktop or virtual machine
viewers which need to inhibit the default system keyboard shortcuts so
that the remote session or virtual host gets those instead of the local
environment.

GTK defines various types that are meant to be derivable only within GTK
itself, and "final" from the perspective of consumers of the GTK API.
The existing macros defined by GObject, such as G_DECLARE_FINAL_TYPE and
G_DECLARE_DERIVABLE_TYPE, lack this functionality.
While we wait for GObject to get this kind of macro, we should define
our own.
Without this, the back buffers of the wrong size
keep being used, causing flickery misdraws, as
seen when expanding the expander in the popover
in widget-factory.
surface->x/y (and various x,y arguments) should be in the parent
coordinates, so treat it as such. We also keep track of the root coords
as these are needed for popup positioning.
Also, drop the isTemp property server side and the weird initial
placement at (100, 100) in the daemon. We now fully control window
placement from the client instead. If this is not we want we should do
a serious design for that but until then lets do the simplest thing.
In firefox, onload will trigger when the image is loaded, but at
that point it may not be decoded yet so showing it will sometimers
trigger flashes. We use the new decode() feature instead which ensures
both that the image is loaded *and* decoded, thus fixing the flashes.
These fixes were done blindly, to make the ci pass,
and will need review by somebody with access to an
actual win32 system to make sure the surface subtypes
are implemented properly.
There is no shape combining going on anymore, so
call this just gdk_surface_set_input_region, and
remove the offset arguments too. All callers pass
0 anyway.
Update all callers and implementations.
This is not quite right, and only temporary, since
it makes GDK_IS_POPUP (surface) true for every surface.
Eventually, the implementation will be moved to the
backends.
Sprinkle various g_assert() around the code where gcc cannot figure out
on its own that a variable is not NULL and too much refactoring would be
needed to make it do that.
Also fix usage of g_assert_nonnull(x) to use g_assert(x) because the
first is not marked as G_GNUC_NORETURN because of course GTester
supports not aborting on aborts.
Drop the input-mode, since it only makes sense for
floating devices, which we don't have anymore. And renamt
::input-source to ::source, to match the getter.
Update all users.
replace all uses with const char * (non-interned).
Also remove a lot fo juggling from atom to GdkAtom to string and back.
The X Atom hash table is now mapping to (again, non-interned) strings.
We were not properly converting the coordinates we
got to root coordinates. This was showing up as offsets
between the actual drop target and the area where drops
can happen, e.g. when dragging over a stack switcher
to switch pages.
We were forgetting to clean up the ::xevent signal
handler in some error cases. Move the signal connection
later, when we know the drag is going forward, and
use g_signal_connect_object to make sure the signal
handler is not forgotten.
This allows treating drop events like touch events, which GTK groups by
event sequence.
It's a bit ugly that we just case the GdkDrop pointer, but event
sequences are only meant to be unique pointer ids, so it's fine.
When a popup is already showing, and gdk_surface_present_popup() is
called, if the layout didn't change, we're not really interested in
relayouting.
In the future, we'll be able to get notified if position of the popup
would change by some environmental changes, but until then, just don't
support it.
Rearrange a few things, and move some booleans
into the Any struct, by using a bitfield there.
Some more cleanup could be done - the flags field
with its PENDING and FLUSHED members appears
entirely unused. Nobody is setting those flags.
Restructure the getters for event fields to
be more targeted at particular event types.
Update all callers, and replace all direct
event struct access with getters.
As a side-effect, this drops some unused getters.
Make the event translator return a new event, instead of
filling in a half-constructed one.
Update the two implementation in GdkX11Display and
GdkDeviceManagerXI2.
Instead of passing a half-constructed event and expect
it to be filled in, pass the surface as in argument, and
add an out argument for a newly constructed GdkEvent.
Add private API to construct events. This is a step towards
making events readonly, and not objects anymore.
The constructors here are sufficient to convert the Wayland
backend over. More may be added for other backends as needed.
Open issues:
- history
Replace the gdk_surface_move_to_rect() API with a new GdkSurface
method called gdk_surface_present_popup() taking a new GdkPopupLayout
object describing how they should be laid out on screen.
The layout properties provided are the same as the ones used with
gdk_surface_move_to_rect(), except they are now set up using
GdkPopupLayout.
Calling gdk_surface_present_popup() will either show the popup at the
position described using the popup layout object and a new unconstrained
size, or reposition it accordingly.
In some situations, such as when a popup is set to autohide, presenting
may immediately fail, in case the grab was not granted by the display
server.
After a successful present, the result of the layout can be queried
using the following methods:
* gdk_surface_get_position() - to get the position relative to its
parent
* gdk_surface_get_width() - to get the current width
* gdk_surface_get_height() - to get the current height
* gdk_surface_get_rect_anchor() - to get the anchor point on the anchor
rectangle the popup was effectively positioned against given
constraints defined by the environment and the layout rules provided
via GdkPopupLayout.
* gdk_surface_get_surface_anchor() - the same as the one above but for
the surface anchor.
A new signal replaces the old "moved-to-rect" one -
"popup-layout-changed". However, it is only intended to be emitted when
the layout changes implicitly by the windowing system, for example if
the monitor resolution changed, or the parent window moved.
We can map a non-grabbing popup wherever, it's just the grabbing
popup-chain that needs to be ensured not to break any ordering rules.
Fix this by managing two lists; one of open popups, and another for
grabbing ones.
The returned position should be relative to the parent surface, but
GdkSurface::x,y were only managed properly for O-R windows. This makes
it correct for regular windows too.
Now popups surfaces are always created with the parent set, so we don't
need to implement vorious guess work to try to find what the parent
might be. Remove that code and just use GdkSurface::parent which is
where the parent set during construction ends up at.
Add event queues specifically for surface configuration events
(xdg_surface.configure, xdg_toplevel.configure, xdg_popup.configure etc)
so that a configuration can be completed without having side effects on
other surfaces. This will be used to synchronously configure specific
GdkSurfaces, as is needed by the Gtk layout mechanisms.
The freezing is conditioned on various state, so lets make the thawing a
bit more robust. Without this there was a risk that we'd thaw too many
times if there was a frame callback requested while the conditions for
the freezing were not met.
