In 9e3785f8cd, a heuristic was added to assume that NORMAL and DIALOG
window types were always focusable. (This was before we had the "offer
focus" mechanism in place.)
However, we should still call wlr_xwayland_surface_offer_focus() for
these views, in case they actually don't want focus. (This is uncommon
but has recently been seen with WeChat popups, which have both NORMAL
and UTILITY type.)
To make this possible, refine view_wants_focus() to return either
LIKELY or UNLIKELY for Globally Active input windows. This decouples
the question of "should we try to focus this view" from the actual
mechanism used to do so.
This fixes the gap between menu items and the menu border in an output
with a fractional scale due to the semantic gap between cairo and
wlroots's position-independent scene renderer.
This patch also changes the semantics of scaled_icon_buffer: rather than
calling scaled_icon_buffer_set_app_id() every time an app_id is set, we
can now call scaled_icon_buffer_set_view() just once so that multiple
scaled_icon_buffers bound to a window are automatically updated when an
app_id is set or new icon is set via xdg-toplevel-icon-v1.
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.
