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
683f67b7 introduced another regression that the modifier state (Ctrl) is
stuck when Ctrl+F is pressed in some applications like Firefox while
Fcitx5 is running. This caused mouse scrolls to zoom in/out the UI.
Let me explain the cause in detail. When Ctrl+F is pressed, an input box
is opened in the application and Fcitx5 creates a new virtual keyboard
(VK), whose initial modifiers is empty. Then prior to 683f67b7, the
key/modifiers events flowed like this:
- The compositor detects F key-release
- Modifiers (Ctrl pressed) are notified via _set_keyboard()
- F key-release is forwarded to IM
- IM sends modifiers (Ctrl) back to the compositor via VK
- **The modifiers on VK is updated (empty->Ctrl)**
- **Modifers (Ctrl) are notified to the app**
- IM sends F key-release back to the compositor via VK
- F key-release is notified to the app
- The compositor detects Ctrl key-release
- Ctrl key-release is forwarded to IM
- Modifiers (empty) are forwarded to IM
- IM sends Ctrl key-release back to the compsitor via VK
- Ctrl key-release is notified to IM
- IM sends modifiers (empty) back to the compositor via VK
- **The modifiers on VK is updated again (Ctrl->empty)**
- **Modifiers (empty) are notified to the app**
Thus, the final modifiers (empty) is notified to the application as
expected. However, after 683f67b7, the key/modifiers events flowed like
this:
- The compositor detects F key-release
- F key-release is directly notified to the app
- The modifiers (Ctrl) is also notified to the app
- The compositor detects Ctrl key-release
- Ctrl key-release is directly notified to the app
- Modifiers (empty) are forwarded to IM
- IM sends modifiers (empty) back to the compositor via VK
- **Modifier on VK is not updated (empty->empty)**
- **The compositor ignores it**
So the final modifier (empty) is never notified to the application, which
causes stuck Ctrl modifier.
This commit fixes this by not forwarding the modifiers when it hasn't been
updated since it was forwarded previously. So after this commit, the
key/modifiers events flow like this:
- The compositor detects F key-release
- F key-release is directly notified to the app
- The modifiers (Ctrl) is also notified to the app
- The compositor detects Ctrl key-release
- Ctrl key-release is directly notified to the app
- The modifiers are directly notified to the app because the modifiers
(empty) are the same as the last forwarded modifier (empty).
Currently we may end up in an endless loop of Reconfigure requests
if the Reconfigure action was called by a keybind. If the reconfigure
takes too long (which may happen on slow systems with libsfdo full
debug logging for example) the reconfigure might be triggered again
and again.
To prevent that, simply cancel all keybind_repeat timers on reconfigure.
After commit e2189903 in wlroots, when ctrl-f is pressed in firefox with
a IME client running, the following key-release event for "f" is not
sent, thus "f" is repeated like "ffffffffff..." in the input box of
firefox. This is because the key-release event for "f" is firstly
forwarded to the IME client and then sent via the virtual keyboard created
by the IME client while the key-press event is sent via physical
keyboard, and with e2189903, key-release events without a corresponding
key-press event on the same keyboard is not emitted to the compositor.
So this commit fixes this problem by not forwarding the key-release event
to the IME client unless the corresponding key-press event was also
forwarded.
For `Drag` mousebinds, `pressed_in_context` is set by
`cursor_process_button_press()` and cleared by `cursor_process_motion()`
which runs actions bound to them. However, when `cursor_process_motion()`
is called while interactive move/resize, it doesn't clear
`pressed_in_context` due to the early-return and the `Drag` mousebinds are
unexpectedly executed on another call to `cursor_process_motion()` after
the interactive move/resize is finished by button release, even when the
button is not pressed.
So this commit fixes it by always clearing `pressed_in_context` on button
releases.
Contrary to the raw tablet events, the cursor events transform
the coordinates based on a mapped output orientation.
Otherwise those events are the same.
...to make keybind actions fire on the release event rather then when the
key is first pressed. This is useful for binding actions to modifier keys
only. The most likely use-case for this is the binding of a Super key to a
menu, for example:
<keybind key="Super_L" onRelease="yes">
<action name="Execute" command="rofi -show drun"/>
</keybind>
If another keybind is issued between the press and release, the on-release
keybind is cancelled.

... 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.
Similar like touch, this is guarded by checking if
a surface accepts the tablet protocol. Also reuse
common cursor logic.
Intialize tablet tools on proximity.
Notify idle manager about activity on events.
We didn't support multiple IME popups since input-method-v2 protocol
has no way to position them individually, but we should support it to
provide IME developers with more programming flexibility.
We currently only support cursor emulation
for absolute motion, thus ignore tools/pens
that use relative motion.
Add a log statement on proximity-in to give
some feedback.
This gives instant feedback when changing cursor theme or size.
It only works for server side cursors or clients using the
cursor-shape protocol.

If keyboard-layout-per-toplevel-window is used, reset the group (index)
for each window on --reconfigure whenever the keymap has changed.
Refactor to use a common configure function for reconfigure and

Fixes#1407
This prevents applications from seeing and handling the release event
for a modifier key that was part of a keybinding (e.g. Firefox displays
its menu bar for a lone Alt press + release).
Before commit e77330bc3f, there were issues with keys becoming "stuck"
if other keys were pressed at the time a keybinding was matched, because
those other keys were included in the "bound" set and the release events
were incorrectly eaten by labwc.
Commit e77330bc3f solved that issue with the "big hammer" approach of
preventing keybindings from working at all if other keys were pressed:
if (key_state_nr_pressed_keys() > 1) {
return false;
}
This is an alternate approach to solving the original problem, by (1)
not including those other keys in the "bound" set and (2) making sure we
always forward release events for un-bound keys to clients (even if a
menu or OSD is displayed).
Details:
- Since we only ever want to store the single matched keycode as bound,
key_state_store_pressed_keys_as_bound() doesn't really make sense in
the plural, so rename it to key_state_store_pressed_key_as_bound() and
pass in the keycode.
- The calls to key_state_store_pressed_keys_as_bound() within
handle_keybinding() appear to be redundant since it is also called
from the parent function (handle_compositor_keybindings()). So remove
these calls.
- Finally, rework the logic for handling key-release events so that we
always forward release events for keys not in the "bound" set.
This PR does not remove the "key_state_nr_pressed_keys() > 1" check, and
because of that should not result in any functional change. It should
however make it possible to relax or remove that check in future.
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.
