Offer focus by sending WM_TAKE_FOCUS to a client window supporting it.
The client may accept or ignore the offer. If it accepts, the surface will
emit a focus_in signal notifying the compositor that it has received focus.
The compositor should then call wlr_xwayland_surface_activate(surface, true).
This is a more compatible method of giving focus to windows using the
Globally Active input model (see wlr_xwayland_icccm_input_model()) than
calling wlr_xwayland_surface_activate() unconditionally, since there is no
reliable way to know in advance whether these windows want to be focused.
v2: add caution not to use view_offer_focus() directly
v3: remove obsolete comment

("Transparently restack xwayland surfaces")
In addition, MR 4772 makes sure the hidden windows are stacked at the
bottom, just like what we did with XWAYLAND_VIEW_HIDDEN.
This allows users to make the icon in window switcher bigger (or smaller)
than the font size, which enables more Openbox-like appearance.
Example configuration:
osd.window-switcher.item.icon.size: 50
This commit also makes the icon smaller than the font size if the width
allocated with <windowSwitcher><fields><field width=""> is smaller than
that.
Before this commit, when a normal window is raised, xwayland thought it's
above always-on-top (AOT) windows even though it's actually below AOT
windows in the scene. This means mouse scroll events may be unexpectedly
sent to normal windows below AOT windows even when the cursor is hovering
over a AOT window.
So this commit fixes it by notifying the correct stacking order (where AOT
windows are placed above normal windows) to xwayland every time the
stacking order is updated.
Other benefits of this commit are:
- It makes the code more readable and predictable by aggregating logic
about stacking order management in xwayland (e.g. shaded windows or
windows in other workspaces should be notified to xwayland as being
placed at the bottom).
- As server->last_raised_view is removed in the previous commit, we were
notifying the stacking order to xwayland every time a window with dialog
windows is clicked (not when clicking a topmost window without dialogs,
due to some optimization in wlroots). This commit fixes this by caching
the window stacking order in xwayland_view->stacking_order and notifying
it to xwayland only when it's updated.
We were skipping in view_move_to_front() if the raised view is already
cached as server->last_raised_view. But this was prone to bugs that
windows cannot be raised even though they are actually not placed at the
top in the scene.
This happened when a window is mapped but view_move_to_front() is not
called in view_impl_map() for some reason. Example cases were:
- a window is minimized before being mapped (#2627)
- a window is mapped while window switcher is active (#2629)
Also, this problem was the root cause of #1640 and #2582, though they are
already fixed.
Therefore, this commit removes server->last_raised_view. In order to
eliminate unnecessary communications between labwc and xwayland (ref:
db591d1), I'll introduce another caching mechanism in the next commit.
This ensures all event listeners are removed before the emitting
wlroots object is being destroyed. This will be enforced with asserts
in wlroots 0.19 but there is no reason to not do it right now either.
This change in wlroots 0.19 is implemented via commit
8f56f7ca43257cc05c7c4eb57a0f541e05cf9a79
"Assert (almost all) signals have no attached listeners on destroy"
This removes the need to call update_client_list_combined_menu()
and update_client_send_to_menu() every time a root menu is opened.
This commit also fixed the incorrect menu position with following
configuration:
<menu id="foo" label="foo">
<item label="aaaaaa"/>
<item label="bbbbbb"/>
</menu>
<menu id="root-menu">
<menu id="foo" />
<menu id="foo" />
</menu>
Before this commit, nothing was rendered in window icon button if the
application doesn't set its app_id (e.g. nested kwin_wayland). This was my
oversight in dc474521.
This commit makes sure fallback icon (set via <theme><fallbackAppIcon>)
by removing ssd->state.app_id and the early-return in
ssd_update_window_icon(). This doesn't affect performance because
scaled_icon_buffer caches app_id and scaled_icon_buffer_set_app_id() does
nothing when a duplicated app_id is passed.
Previous commits fixed some unexpected behaviors when ShowMenu action is
executed from menu items, but that was still prone to bugs because when
calling actions_run(), we allow an inconsistent state where all menus are
closed but pipemenus must not be destroyed.
So this commit simply removes ShowMenu actions from menu items on
initialization.
Eliminate corner extents and instead use cursor position to map SSD
borders and extents to corner contexts, with a size configurable by the
<resize><cornerRange> parameter. This simplifies extent handling,
eliminates bugs in the detection of corner context, and allows users to
expand corner targets if they wish.

This commit adds <theme><fallbackAppIcon> that configures the icon name
to be used when lookups for an application icon is failed. Its default
value is set as 'labwc' which shows our labwc logo.
padding_x in lab_img_render() was just to make sure window icons in the
titlebar doesn't get too close to adjacent buttons and it didn't felt
clean. To remove it from lab_img, this commit changes the size of window
icon buffers from (window.button.width)x(window.button.height) to
(window.button.width * 0.8)x(window.button.height) and horizontally
slide it by (window.button.width * 0.1) to keep the horizontal padding.
Note that the size of the hitbox for a window icon is kept the same and
nothing is changed from user's perspective.
This prevents potential bugs that buffers created by scaled_scene_buffers
before Reconfigure are reused by other newly created scaled_scene_buffers.
This is targeted for scaled_icon_buffer whose buffer creation depends on
server->sfdo.
And make mousebind handlers use that one.
Also remove keyboard_any_modifiers_pressed() and replace its usage
with the new function.
Without this patch we would only request the modifier state of the
keyboard group which makes mousebinds involving keyboard modifiers
break for virtual keyboards like when using wayvnc. Same story for
hiding the workspace overlay or snapping to regions.
Fixes: #2511
This fixes an issue with buffers not updating when an output is configured
for a new scale. It also supports windows being on more than 2 outputs at
once and in general simplifies the code.
This patch splits desktop_entry_icon_lookup() into two separate functions
- desktop_entry_load_icon(): load a icon from the configured icon theme
- desktop_entry_load_icon_from_app_id(): load a icon name from a .desktop
file based on the given app_id and supply it to _load_icon().
The _load_icon() function will be used in a future menu icon
implementation whereas the _load_icon_from_app_id() function is used
within the SSD titlebar window icon lookup routine.
