This patch is based on the original stale patch by Guido Cella @guidocella.
It has been modified to apply cleanly to the latest v5.0 tag. Since the SLOC
limit is now lifted, this core feature should be merged into dwl upstream.
Thanks to Dima Krasner @dimkr for the cherry-pick.
Closes: #559, #525
When a user's startup_cmd is a little more complex, e.g. a shell script,
and forks off several processes, then killing only the main child pid
might leave unwanted processes behind on exit. Not all children will
notice when their parent or the compositor has quit.
To fix this, put startup_cmd into its own session and process group, and
kill the entire group on exit.
bemenu is very bloated, turning itself into a library, which makes it
7489 SLOC.
wmenu on the other hand, looks suckless by default, and is only 2000
SLOC, which i also find alot nicer to use, since bemenu does nothing
to replicate the original dmenu feel.
Make example rules be actual EXAMPLES.
Now newcomers should not have to ask, "When I start firefox, nothing
happens. What is going on?"
Also clarified a minor typo and a consistency in spacing.
When motionabsolute() is called from warpd, event->time_msec is 0, so
motionnotify() doesn't call wlr_cursor_move(). Fix this by explicitly
warping the cursor in this case, like it was done before implementing
pointer constraints.
I don't know if this is a bug in warpd or time_msec is always 0 with
virtual pointers, since the only other software that uses the virtual
pointer protocol I know of is wl-kbptr, and I can't get that to work
with dwl at all.
When a child window of a fullscreen client is mapped, the fullscreen is
disabled, and if the previously fullscreen client is floating the child
window is rendered below it and cannot be seen, causing confusion,
though it is still focused and interactable.
Fix this by putting children of fullscreen clients in LyrFS instead of
LyrFloat, and by returning before the unset_fullscreen code is called
when they are mapped.
focusstack() now lets you switch focus from a fullscreen client to its
child windows, otherwise if you switch focus from the child window to
the fullscreen client you could not focus the child window again and the
fullscreen client would stay unresponsive.
Child clients are not reparented to LyrFloat after leaving fullscreen,
so you could spawn a child window, focus back the fullscreen client,
unfullscreen it, and the child window would still be drawn above other
floating clients. Avoid dealing with this edge case to keep the line
count low.
These cases can be tested by pressing Ctrl+o in applications with an
open file dialog.
Revert 3213088 because the linked bug can no longer be reproduced with
wlroots 0.17, and update client_get_parent() so it doesn't segfault with
XWayland surfaces. This also allows reusing the p variable in the next
commit.
These don't do anything because wlr_scene_node_reparent() is immediately
called again by setfloating() through setmon(). They are also a source
of confusion because if you change the wlr_scene_node_reparent() call in
applyrules() it takes a while to understand why it doesn't work.
For wine clients often configurex11() is called before mapnotify() and
therefore c->mon is NULL. configurex11 just returns early in that case,
letting these clients stay in the wrong size. For example only the top
left part of winecfg and wine uninstaller is drawn, or confirmation
dialogs like when closing wine notepad are too big. Fix this by
configuring their surfaces like before 88d386b.
