In OpenBox, when cursor button is pressed to open menu, a subsequent
cursor button release can perform actions or close the menu.
This commit makes labwc follow that behavior.
Fixes: #1750
Add optional drop-shadows to windows using server-side decoration.
Shadows can be enabled/disabled rc.xml and their appearance configured
in themerc. The default is no shadows to preserve current behaviour.
The shadows are drawn in fixed corner and edge buffers shared between
all windows, the edges are scaled to size depending on the size of each
window. Two sets of buffers are used to give the different appearances
for active and inactive windows. I use separate corner/edge buffers for
a few reasons:
- It avoids needing to store a separate large shadow buffer per window
- It avoids needing to redraw the shadows when the window is being
resized
- Compositing the shadows onto the desktop should be faster as there are
overall fewer pixels to blend, and scaling up the edge buffers only
requires reading a tiny buffer which is then replicated.
Filled/outlined rectangles shown as snapping overlay are now enabled/disabled
independently with `snapping.overlay.[region|edge].bg.enabled` and
`snapping.overlay.[region|edge].border.enabled`.
To keep the default behavior, `*.bg.enabled` is yes and `*.border.enabled` is
no for hardware-based renderers, while `*.bg.enabled` is no and
`*.border.enabled` is yes for software-based (pixman) renderer.
Users can now use a filled rectangle as an overlay even with pixman renderer.
However, this may severely impact performance when used with translucent
`snapping.overlay.[region|edge].bg.color`.
This commit includes a refactor to use substruct `theme_snapping_overlay`
inside `theme` in order to pass it to `create_overlay_rect()` in a cleaner way.
Breaking changes is:
- `snapping.overlay.[region|edge].fill` is now removed.
Replace "preview" in rc.xml and themerc with "overlay" since "preview" sounds
like it shows the window content.
Breaking changes are:
- `snapping.preview.*` in themerc is now replaced with `snapping.overlay`.
- `<snapping><preview>` in rc.xml is now replaced with `<snapping><overlay>`.
Before this patch, labwc would happily kill itself when the user
called the `Kill` action when any xwayland view had focus.
The reason this happened was that wlroots creates the xwayland
wayland client via socketpair() and thus a lookup of the pid
of the socket connection would return the pid of labwc itself.
This patch fixes that by implementing different pid lookup
mechanisms based on the view implementation backend.

Changes in `<desktops><names>` or `<desktop><number="" prefix="">` required
restarting labwc to take effect.
This commit adds `workspaces_reconfigure()` to update `server->workspaces` on
Reconfigure.
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.
This allows to ignore X11 client side configure requests
like positioning and resizing and can be used to fight
some X11 applications that persist to have their windows
spawn at specific places and sizes.
Fixes: #1446
When Fcitx5 is activated, it creates a virtual keyboard to send keycodes to
applications, then creates a keyboard grab to capture keycodes the user typed.
Before this commit, we set keyboard grab's modifiers to that of currently
active keyboard, which is the virtual keyboard created in the case described
above. However, since the modifiers of the virtual keyboard is empty at first,
we actually set empty modifiers, even when the user is pressing modifiers.
Then, Fcitx5 assumes no modifiers is pressed and redirect the modifier state
back to the compositor via the virtual keyboard. As a result, when the focus
is switched between windows by workspace-switcher, the workspace-switcher is
immediately terminated.
To fix this issue, with this commit, the modifier state of the currently active
keyboard is not set to the keyboard grab if the keyboard is a virtual keyboard
created by the same input-method client.
Fcitx5's commit below is also required to fix the issue.

.clang-format gets picked up nowadays by some IDEs (tested Qt Creator)
for auto-formatting aids. With the large caveat that it's not 100%
accurate to labwc's preferred coding style, I've found that this config
gets it right 90% of the time, which is enough to be helpful.
I added a prominent disclaimer comment to the top of the file to warn
people away from relying completely on clang-format. This isn't meant
to replace manual attention to formatting details (or to replace
./scripts/check) but I think it doesn't hurt.
Add a BUF_INIT macro, which makes it easier to initialize a struct buf
to an empty string (without a heap allocation).
Add buf_move() to move the contents of one struct buf to another (the
source is reset to BUF_INIT, analogous to C++ move-assignment).
Use buf_reset() instead of directly calling `free(s->buf)` since the
internal buf may not always be allocated by malloc() now.
Before this patch, the OSD would repeat the last buffer
content in case the new buffer content would be empty.
This was mostly happening for the `title` OSD field that is intended
to be empty when it matches the app_id / WM_CLASS of the application.
Due to only buffer.len being reset but its internal allocations being
untouched, buffer.buf would still carry the old data.
This patch fixes it by also overwriting the first byte in the buffer
allocation with '\0' via the new `buf_clear()` function.
Do the same for buf_expand_shell_variables() although that one should
have been fine before as it always writes new data to the buffer.
...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

When growing or shrinking a view by snapping to an edge, a client may
ignore the requested size and instead keep its original size or
substitute a different (possibly constrained) size. In this case, the
view may not actually contact the snapped edge, and a subsequent snap
attempt will just keep re-trying (and failing) to contact the same ege.
To mitigate this, remember the last-snapped view, snapping direction and
offset of the snapping edge in snap.c; when re-attempting a snap for the
same view in the same direction, ignore the edge that was last "hit", to
allow snapping to progress beyond the problematic edge.
This fixes an issue detected by the static analyzer.
Rather than setting up the new popup as usual return
a wayland error to the client and destroy the popup.
This fixes an issue detected by the static analyzer.
It currently is not a real bug but it could become
one in the future if `add_toggled_icon()` is called
before `add_scene_button()`.
Rather than having `add_toggled_icon()` go through
the list, find the root button and then fetch its
node descriptor just supply the button as argument.
Fill with the background color first only if the background color is
opaque. This is necessary for subpixel rendering to work properly (it
does not work on top of transparency).
However, if the background color is not opaque, leave the buffer
unfilled (completely transparent) since the background is already
rendered by the scene element underneath. In this case we have to
disable subpixel rendering.
v2: use 0.999 alpha cutoff and fix CodeStyleCheck
Fixes: (the rest of) #1684
Add ability to set width with percentage of monitor instead of just pixels.
With this the OSD sizes itself properly on both my 4k and 2k monitors.
example: 50% or 75% instead of 600, max 100%
