wlroots < 0.17 didn't allow to reliably check the source surface of
an xdg activation request as it reset the surface to NULL when it
was destroyed before the token was used. This happens regularly for
notifications for example. Thus we treated the token as valid even
without checking for the source surface.
wlroots 0.17 added a new_token signal where we can attach information
to the existing token which we can then use when evaluating activation
requests. This patch implements that check.
...when cycling windows. Also make the toggling of direction when shift
is pressed relative to the initial direction. For example if W-j is
bound to PreviousWindow, subsequent key presses will continue to
cycle backwards unless shift if pressed.
Add documentation for using shift/arrow keys in Next/Previous
... at the same time. Omit cursor notifications from
a pointer when a tablet tool (stylus/pen) is in
proximity. We expect to get cursor notifications
from the tablet tool instead.
- Replaced `session_lock` with `session_lock_manager` which is
persistent throughout the session.
- Replaced `session_lock->abandoned` with `session_lock_manager->locked`.
Old `session_lock->abandoned` is equal to
`!session_lock_manager->lock && session_lock_manager->locked`.
- Eliminated the use of global variables in `session-lock.c`.
- Changed some function names.
There were some missing headers like <stddef.h> for `NULL`, <wayland-util.h>
for `wl_link` and <stdbool.h> for `true`/`false`.
Also this commit fixes that `labwc.h` and `ime.h` included each other.
...to start <command> on startup and to terminate the compositor when
<command> exits.
This is useful for session management as it allows the session client (for
example `lxqt-session`) to terminate labwc - be exiting itself.
Under X, xinit starts the server and keeps it alive for as long as
lxqt-session runs. Thus either the session client starts the Window
Manager, or the Window Manager can be launched independently first. On
Wayland, the Compositor is both Display Server and Window Manager, so the
described session management mechanisms do not work because the Compositor
needs to be running before the session can function.
As some session clients support both X11 and Wayland, this command line
option avoids re-writes and fragmentation.

Add custom field with subset of printf style formatting
to replace the original field formats.
Example:
<windowSwitcher preview="no" outlines="no" allWorkspaces="yes">
<fields>
<field content="custom" format="foobar %b %3s %-10o %-20W %-10i%t" width="100%" />
</fields>
</windowSwitcher>
Mono space font recommended. May need OSD width adjusted

...and unify region overlay and snap-to-edge overlay into overlay.c.
Snap-to-edge overlay is delayed for 500ms to prevent flickering when
the view is dragged from an output to another (demo in discussion labwc#1613).
This also fixes a bug that region overlay is not shown when a modifier
key is re-pressed.
Move/resize requests from xwayland views and xdg toplevels should be
ignored when the view is not pressed.
This is relevant for touchpad taps with <tapAndDrag> disabled.
When the user taps the client surface (e.g. chromium and mpv) with the
setting above, libinput sends button press & release signals so quickly
that the compositor receives move/resize request from the client AFTER
the button release signal is processed, so `interactive_finish()` is
never called.
This commit moves the virtual output related functions
into their own file at `src/output-virtual.c` with its
own include file to reduce `include/labwc.h` bit by bit.
Additionally, it removes the need to keep the
`server->headless.pending_output_name` char array around
by temporarily disconnecting the handler when creating a
new virtual output. This allows to set the output name
right in the `output_virtual_add()` call rather than to
store the pending name until the new output event handler
has been called.
It also makes adding a virtual fallback output easier in
a follow-up PR.

backend/wayland: use request_state when toplevel is resized
Chases: 3ef68a484243555b020200c6f95246d994932c3f
backend/x11: use request_state when window is resized
Ref: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/2693
We now delay requested resolution changes by the backend until
the next frame event which causes us to render the new content
on the already enlarged buffer. Before this change, an empty
(black) buffer would have been shown instead before the next
frame event caused a new render of the actual contents.
Keep commiting the new state and then scheduling a frame event
would not help as due to the commit call it would still show an
empty buffer in the meantime.
Just modifying wlr_output->pending wouldn't work either because
wlr_scene_output_commit() *completely* ignores it (and it will
be removed in future wlroots commits). For this reason we move
to wlr_scene_output_build_state() directly because it allows us
to supply the current wlr_output->pending state and thus apply
any resolution change in lockstep with new rendering. Result:
No more flickering in the wayland backend and resizing is again
smooth as butter.
This prevents constant flicker while resizing
when running nested via the wayland backend.
For the X11 backend (can be tested via `WLR_BACKENDS=x11 labwc`),
it is still rather janky but at least doesn't cause endless self-
resizing anymore.
Fixes#1076
It can be enabled with a config like
~/.config/labwc/rc.xml:
<keyboard layoutScope="window">
~/.config/labwc/environment:
XKB_DEFAULT_LAYOUT=de,us
XKB_DEFAULT_OPTIONS=grp:alt_shift_toggle,grp_led:scroll
With a configuration like this each window should now remember
the active keyboard layout when switching between windows.
By default, the keyboard layout keeps being a global state.
We already allow some xwayland-unmanaged surfaces to take focus on map,
if indicated by wlr_xwayland_or_surface_wants_focus(). But once these
surfaces lose focus, they never regain it again.
Add desktop_focus_view_or_surface() and call it in the appropriate
places to allow these views to regain focus in the usual ways (e.g.
clicking on them or focus-follows-mouse).
We were checking for a locked session in desktop_focus_view(), but there
are several other call sites of seat_focus_surface() which were missing
such a check. Any one of those could cause the lock screen to lose focus
(making the session impossible to unlock) or another surface to gain it
(breaching the session lock).
To fix the issue, make any call to seat_focus_surface() no-op when the
session is locked. Add a specific seat_focus_lock_surface() function
which is the only way to bypass the check and is called only from
session-lock.c.
XWayland views can self-declare that they don't want keyboard focus via
the ICCCM WM_HINTS property. Most of the logic is already in place to
avoid giving focus to such views (e.g. taskbars).
Add a couple of missing pieces to make this work:
- Hook up view_isfocusable() to look at WM_HINTS for XWayland views
- Adjust desktop_focus_topmost_mapped_view() to skip unfocusable views
- Connect to wlr_seat_keyboard_state's focus_change event.
- Add view_from_wlr_surface(), which does what the name says.
- Use focus_change event along with view_from_wlr_surface() to update
server->focused_view and set SSD states via view_set_activated().
- Eliminate desktop_focused_view() since server->focused_view should be
reliably up-to-date now.
- Eliminate view_focus/defocus() since we can now just call
seat_focus_surface() directly.
