* exwm-systemtray.el (exwm-systemtray--refresh-background-color):
Add optional parameter REMAP to force redrawing of the background.
(exwm-systemtray--on-theme-change): Use it.
* exwm-systemtray.el (exwm-systemtray-background-color): Add
support for using current workspace's background color as system
tray background color.
(exwm-systemtray--refresh-background-color): New function to set
the background color upon theme changes or workspace switches.
(exwm-systemtray--on-workspace-switch)
(exwm-systemtray--on-theme-change): Use it.
(exwm-systemtray--init): React to theme changes.
We were using the Emacs' frame's depth, but not the visual nor colormap.
This failed with Emacs 29 and its support for 32-bit depths.
We now use the default screen's visual: using a non-default visual in
the system tray requires support for embedding icons with different
visuals, which is not implemented. We restrict our limited transparency
support to Emacs frames with depth equal to the default visual's detph.
* exwm-core.el (exwm--get-visual-depth-colormap): New function.
* exwm-systemtray.el (exwm-systemtray--init): Use root window's
visual, depth and colormap. Reset all attributes that refer
(perhaps due to defaults) to the parent window, as it might have a
different visual, depth or colormap.
(exwm-systemtray--init): Set _NET_SYSTEM_TRAY_VISUAL.
(exwm-systemtray-background-color): Emit a warning when
transparency is selected but not supported.
(exwm-systemtray--set-background-color): New function to set
embedder window background.
(exwm-systemtray--embedder-window-depth): Add variable.
(exwm-systemtray--transparency-supported-p): New function to check
whether transparency is supported.
* exwm.el (exwm--on-ClientMessage): Take care of focusing
workspace frames when a _NET_ACTIVE_WINDOW message is received for
a workspace frame. This is responsibility of the window manager
when it advertises _NET_ACTIVE_WINDOW support, which we do.
Emacs versions before 29 took care of setting the input focus to
the frame.
Thanks-to: Po Lu for the work on Emacs and assistance with this
issue.
* exwm-core.el (exwm--get-visual-depth-colormap): New function.
* exwm-workspace.el (exwm-workspace--add-frame-as-workspace): Use
Emacs' frame's visual, depth and colormap. Reset all attributes
that refer (also by default) to the parent window (the root
window), as it might have a different visual, depth or colormap.
Special-thanks-to: Elijah Malaby <qwe12345678910@gmail.com> for figuring out the
changes needed to suport 32-bit visuals and proposing the initial
version of this improvement.
* exwm-workspace.el (exwm--client-p-hash-table): New variable.
(exwm-workspace--client-p): Use `exwm--client-p-hash-table' to
store which workspace frames are client frames instead of
frequently invoking `frame-parameter'.
* exwm-layout.el (exwm-layout-set-fullscreen,
exwm-layout-unset-fullscreen): Use `exwm--id' for interactive use.
(exwm-layout-unset-fullscreen): Mandatorily clear fullscreen states.
* exwm-xim.el (exwm-xim--handle-forward-event-request): Send all key
events to Emacs while invoking an input method (don't rely on its
keymap definition).
* exwm-input.el (exwm-input-input-mode-change-hook): Add new hook
for code to run upon input mode change.
(exwm-input--grab-keyboard, exwm-input--release-keyboard): Run it.
* exwm-workspace.el (exwm-workspace-switch): Stop aborting
recursive edit upon switching workspaces. Users should handle it
just like in regular Emacs (possibly customizing
`enable-recursive-minibuffers').
* exwm-workspace.el (exwm-workspace-switch): Abort recursive edit
before switching to other workspace. This avoids the usual
`set-window-configuration' calls (e.g., by `eval-expression') to
switch *us back to the previous workspace.
* exwm-layout.el (exwm-layout--set-ewmh-state): New function for
setting _NET_WM_STATE (according to local state).
* exwm.el (exwm--init-icccm-ewmh): Declare the support for this atom.
Local variable `exwm--input-mode' from different buffer when current buffer don't contains #id window.
`with-current-buffer' changes buffer after `cl-case' with local `exwm--input-mode'
* exwm-input.el (exwm-input--noop): New placeholder command.
(exwm-input--on-pre-command, exwm-input--on-post-command): Ignore this
command.
(exwm-input--on-KeyPress-line-mode): Set `last-command' to make
winner-undo start over from the newest config; run
`post-command-hook' to make winner-mode save configs; run
`pre-command-hook' in case required by some other package.
