(input-method-v2: Destroy keyboard grab before input method)
Background:
My MR in wlroots (!5107) stopped emitting `wlr_input_method_v2`
on its `commit`/`destroy` events, but didn't stop emitting
`wlr_input_method_keyboard_grab_v2` on its `destroy` event. That was
because `handle_keyboard_grab_destroy()` was called *after*
`handle_input_method_destroy()` for some reason, which caused segfault
when dereferencing `relay->input_method.keyboard_grab` in
`handle_keyboard_grab_destroy()`.
MR 5170 reversed this weired order of destroy handler calls, and finally
stopped emitting `wlr_input_method_keyboard_grab_v2` on its `destroy`
event.
- connect/disconnect map handlers in set_surface()
- call set_surface() at time of associate/dissociate
This separates the concepts of "associate" and "map" more clearly.
It's no longer necessary to listen for wlr_surface "destroy" event,
because dissociate is always received first.
Also, view->content_tree is now destroyed and set to NULL at unmap.
Previously, we relied on wlr_scene to destroy it automatically when
the surface was destroyed, but kept a potentially dangling pointer in
view->content_tree until next map. Similar change for unmanaged.
v2: comment updates
We were only using it to allow quick bitset comparisons of sets of
outputs (such as view->outputs). We can maintain our own bit IDs for
this purpose and avoid using the private wlroots field.
Note: from my reading of wlr_scene_output_create(), it appears to
always take the lowest unused index, resulting in aggressive re-use of
index values when outputs are disconnected and reconnected. I've tried
to make re-use as infrequent as possible. This could theoretically
reduce the chance of a mix-up in view_update_outputs(), although I'm
not aware of any practical scenario where it matters.
v2: prevent adding more than 64 outputs
Map/unmap logic is currently re-used for minimize/unminimize, but lots
of it doesn't actually apply in that case. This is both confusing and
creates some extra complexity, such as:
- extra "client_request" parameter to unmap(), in which case it has to
still do some cleanup even if view->mapped is already false
- various "view->mapped || view->minimized" checks when we really just
mean "is the view mapped"
To clean this all up, let's put the logic that really is common into
a new view_update_visiblity() function, and stop using map/unmap for
minimize/unminimize.
Note that this changes the meaning of "view->mapped", which used to
mean "mapped and not minimized" but now really just means "mapped".
I left some "view->mapped" conditions as-is (rather than changing to
"view->mapped && !view->minimized") where it seemed to make sense.
v2: add view_update_visibility() as suggested by tokyo4j
Two were missing: "minimized" and "activated".
At least "minimized" can be set before map, so the initial state needs
to be read and set on the foreign-toplevel.
I think in the current code, the foreign-toplevel is always created
before a view is activated, but for future-proofing, let's not rely
on this, and set "activated" as well. There's no harm since wlroots
optimizes away any redundant state changes.
Since d7dc6e01b4 ("Chase wlroots: Unified mapping"), the map event
is emitted by the wlr_surface itself, thus it cannot be NULL.
Change the "if" to an "assert" accordingly.
Call configure_libinput() for keyboards in new_keyboard() and
seat_reconfigure().
This allows the use of the sendEventsMode configuration option on
keyboards in order to disable keyboard input, for example:
<libinput>
<device category=" RPI Wired Keyboard 1">
<sendEventsMode>no</sendEventsMode>
</device>
</libinput>
Adds `output` attribute to control which monitor(s) display the window
switcher OSD. Supports three modes:
- "all": display on all monitors (default)
- "pointer": display on monitor with mouse cursor
- "keyboard": display on monitor with keyboard focus
The configuration structure is also refactored to nest OSD-specific
settings (show, style, output, thumbnailLabelFormat) under an <osd>
element within <windowSwitcher>, improving logical organization.
The previous "minimal fix" (5148c2aa31) worked but was a bit of a
hack, as it basically un-minimized and then immediately minimized the
view again at map. It's not actually too difficult to make the map
handlers aware of minimized views, eliminating the need for the hack.
Note: this depends on the previous commit ("xwayland: connect commit
and surface_destroy handlers together") otherwise the xwayland map
handler registers the commit handler twice, leading to a crash.
Factor out set_surface() which consolidates connecting/disconnecting
the wlr_surface event listeners in one place.
In theory, this means we can receive commit events for minimized views.
However, with a test app that resizes itself, I didn't see any change,
i.e. the commits still don't come through until un-minimize. It's
possible they are being filtered at wlroots or protocol level.
Also remove an old, semi-related TODO from view.c.
It's possible for a fullscreen xwayland view to be unmapped without
being destroyed. In this case, we need to update top layer visibility,
otherwise panels and the like will remain hidden.
Since unmap is always called before destroy, it's sufficient to do the
update only in view_impl_unmap() and not in view_destroy().
Adaptive sync logic needs work still, but I tried to minimize changes
to it since I don't have hardware to test it.
This commit adds `<windowSwitcher thumbnailLabelFormat="%T">` to configure the label text in each item in the thumbnail-style window switcher. Its format follows `<fields><field content="custom" format="">`.
This allows us to share common codes for dealing with osd items.
For example:
- Get the clicked osd item to focus its associated window
- Scroll the items when their total height is taller than output height
Before this commit, output transformations were not taken into account for
parcent-based osd widths like:
osd.window-switcher.style-classic.width: 80%
osd.window-switcher.style-thumbnail.width.max: 80%
