When modal dialogs are attached, and we set the parent/transient-for
after setting the modal type, the attachedness isn't updated. This is
(apparently) not the case for X11 windows, as they go through a
unmanage/manage dance avoiding the issue.

The service channel D-Bus interface aims to be a "back door" for
services that needs special casing in Mutter, e.g. have custom private
protocols only meant to be used by that particular service.
There are currently no special casing implemented; only the basic
service channel infrastructure is added. There is a single method on the
interface, that is meant to eventually be used by
xdg-desktop-portal-gnome to open a Wayland connection with a private
protocol needed for the portal backend's rather special window
management needs.
The service channel Wayland client works by allowing one instance of
each "type", where each time needs to be defined to work in parallel. If
a new service client connects, the old one will be disconnected.
MetaWaylandClient's are used to manage the service clients, and are
assigned the service client type.

On X11, the stage itself is backed by an XWindow, and moving the
input focus elsewhere will bypass any Clutter-level grabs.
This effectively allows newly opened windows to steal the focus
from gnome-shell itself, which is clearly undesirable. To prevent
that, only allow moving the X11 focus to a Window when no grab is
in place, just like commit 50e89e376 did for the stage focus.
But particularly the updating of x11_display->focus_xwindow is not
prevented. Since it's more consistent to the MetaDisplay/MetaX11Display
dual focus tracking and across Wayland/X11 backends, ensure the X11
input focus is actually set on the last focus Window after the
grabs are gone and windows became interactable again.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2832>
This patch unfortunately results in situations where it is intended
that the focus change happens while a grab is present (e.g. Alt+tab
popup), resulting in confused focus state.
This commit is reverted in order to try a similar approach at a
different level.
This reverts commit 7531669b4f.

ClutterActions now no longer receive their events via
clutter_actor_event(), instead they get special treatment by the stage
now. Make the MetaGestureTracker work with this and stop emitting events
directly to Clutter via clutter_actor_event(), but instead let them get
through to Clutter (but still not to Wayland).

The previous logic tried to keep the position of the top left corner of
the window relative to the top left corner of the monitor. This allowed
the window to move out of the target monitor. This change keeps the
proportions of the distance between the window and the monitor borders
instead if possible. Otherwise it keeps the relative position of the
center of the window clamped to [0,1] to make sure the window lands on
the right output.
This also slightly changes what monitor is considered to be on: the
monitor which contains the center of the window and, if the center is on
no monitor, the monitor wich overlaps the most with the window.

At least indirectly, this is set as object qdata while the
window drag is ongoing, and reset/reconstructed if needed.
Consequently, this edge data does not need to be stored in
the MetaDisplay struct anymore.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
Even though the data is still stored in the display, add a "high
level" meta_window_drag_update_edges() call, so that the cached
edges may be updated while a window drag operation is ongoing.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
This is a public API change. Add device/sequence parameters to this
operation, so that window dragging and resizing can stick to one
set of pointing events of them all.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
Since MetaWindowDrag took a lot of this code to handle window drags
internally with less interactions with the rest of the stack, this
code in display/window/keybindings is unused.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
Flip the switch in using MetaWindowDrag, leaving display grab
ops and a bunch other code unused. Some places checked the grab op
and/or window in complex ways, others just checked for grab existence
and should now look for clutter ones, and others already were already
doing this in addition.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
We only allow partial grabs in the case of a keyboard-type MetaGrabOp
happening while the pointer cannot be grabbed. In that case, it's not
a big stretch to unconditionally ungrab the pointer device at the time
of undoing the grab, as it will be always ineffective (not even implicit
grabs on frame windows can happen now, inside Mutter).
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
This is no longer necessary, since the SSD frames are no longer
part of Mutter process, so it is not the MetaX11Display connection
which holds the implicit grab when a mouse button is pressed over
a window frame (say, to start a drag).
As the SSD frames client communicates the same way than CSD windows
for window operations, it is also expected to undo its implicit
grab before requesting a window move/resize operation.

The final effect of this boolean can now be expressed through the
META_GRAB_OP_WINDOW_FLAG_UNCONSTRAINED flag to MetaGrabOp. Use that
in the relevant places, and drop the argument.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
Now that it is called from a single place, there's a few arguments
that are unnecessary:
- button and modifiers are unused
- already_grabbed was originally added to handle grab transitions between
window menus (GtkMenus, back in the day) with display grabs. It's no
longer necessary now
- frame_action can be passed through the META_GRAB_OP_WINDOW_FLAG UNCONSTRAINED
flag
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
Leave meta_window_begin_grab_op() as the only public API to initiate
a display grab. There's no longer grab operations that don't attain
windows, and ending these grabs usually happen through user interaction
when the right circumstances happen.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
There is no longer reason to call meta_display_begin_grab_op() except
for window grab operations, and meta_window_begin_grab_op() is a
perfectly fine entry point for all window grab operations.
Move away from meta_display_begin_grab_op().
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
Currently, it is thought out to be called with META_GRAB_OP_KEYBOARD*
grab op parameters. Make it more generic so it can also be called for
pointer operations (avoiding pointer warping in that situation).
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
Unlike the comment suggests, this piece of event handling manages
the ungrabbing of a window on button press in the following 2
conditions:
- If a keyboard grab operation was triggered, the window does
additionally follow the pointer, and first button press ends
the grab.
- If a button-press grab is ongoing on the window, but more buttons
are pressed.
We can simplify this to just happen every time a button press event
is received while a window grab op is ongoing. The only case where
this might diverge a bit is same button presses from different
pointer devices, and it's not a big stretch to also undo the grab
in that situation.
This also happens to make the "button" argument in
meta_display_begin_grab_op() completely unused.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
The frame_action boolean is only used by constraints.c code, in order to
determine whether a moving window should be able to move past the top
bar or not.
We can avoid the special casing by passing this information as a
META_GRAB_OP_WINDOW_FLAG_UNCONSTRAINED flag passed with the grab op.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
The whole reason for META_GRAB_OP_WAYLAND_POPUP to exist is to
avoid windows from being activatable/movable/resizable when a
grabbing xdg_popup is active.
Use the meta_display_is_grabbed() method which can tell this
from existing MetaWaylandCompositor grabs, so that this remains
true after dropping META_GRAB_OP_WAYLAND_POPUP.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
Make this public API check just return a boolean about whether
there is an existing grab, instead of exposing MetaGrabOp.
It is desirable to avoid exposing details like
META_GRAB_OP_WAYLAND_POPUP, so that MetaDisplay and wayland
grabs can port to ClutterGrab at their own pace, but also
this further information is unused.
This is likely to be temporary API anyways, after both
MetaDisplay and wayland grabs port to Clutter, it will be
possible to check the ClutterStage for all of them.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
Rewrite this codepath so it handles the grab ops that it cares
about, and ignores the rest. This way the code works despite
possible future modifications to MetaGrabOp (e.g.
META_GRAB_OP_WAYLAND_POPUP removal).
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
This piece of event handling only applies on windows receiving events while
the display is ungrabbed (i.e. for raising it, or beginning a move/resize
operation).
Move the checks on the current grab operation outside of window.c and into
events.c, so all checks about the current grab operation move closer to the
main event handler.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
Some tests expect warnings to be logged, and handle that using
g_test_expect_message(). However, if debug topics are enabled, this
causes g_logv() to expect expected messages to also contain entries with
the debug level 'message' or higher to be listed in the expected message
list. Since meta_topic() always logged using g_message(), enabling debug
topics caused any test that used g_test_expect_message() and had debug
logging somewhere along the code path to fail.
Fix this by changing the log level of meta_topic() to 'debug' if we're
in a test. This doesn't mean they won't be visible, they still will
since debug log entries are printed by default during testing.
