With the recent changes in output-management, the extra argument in
closemon() would be needed only when unplugging the monitor, so it isn't
worth it anymore. Also now is more efficient.
m->link.next leads to errors if the monitor to disable doesn't have a
"next" (right) monitor and is currently focused. dirtmon() does more
checks.
In some previous commits m->link.next is told to be left monitor, which
is wrong
Also focusclient() explicitly checks for disabled monitors (this fixes
in case of more than one disabled monitor)
Focus the top client on newmon, which we know for sure that it isn't
going to be unplugged or disabled and actually set that as the focused
monitor to move the focus. This is necessary to prevent crash when
disabling monitors with the output-management patch.
This allows to fix output-management: move clients to the monitor on the
left of the disabled one, instead of the leftmost (which might happen to
be the disabled one)
Also using wl_list_foreach() and then brake after the first iteration is
ugly and inefficient
When using wlr-randr every monitor's configuration is reevaluated, so it
must check which monitors are actually being disabled. The only way to
correctly do that is to compare the names.
When a monitor is disabled with wlr_randr, all clients on that monitor
aren't lost but they are moved to the leftmost monitor with the same
method that handles monitor hot unplug
There is no need to repeat this. This needs to be reculalculated in my
output-management implementation too, and since I'm already calling
updatemons, this patch avoids having to repeat the assignment again.
quitfullscreen() was replicating the functionalities of setfullscreen(c,
0)
Reusing setfullscreen() in quitfullscreen() leads to a 3 line function,
which is useless since quitfullscreen() is used once anyway
This fixes the bug that happens when changing workspace (or any time
arrange() is called) where there are fullscreen windows, which are still
fullscreen but leave the space for layer surfaces like waybar (which
should be hidden when going fullscreen)
Also as soon one fullscreen window is found hte function returns to
improve efficiency
Floating widndows with "x < removed monitor's width" aren't resized
(they used to disappear in negative coordinates).
Actually delete monitors when they are unplugged, recalculate sgeom and
give a new monitor to clients that were on the removed one with setmon()
arrangefloat() funcion has been exploded to save iterations in
cleanupmon().
Also if a monitor that supports auto suspension is turned off, dwl will
count it as unplugged (it will become unreachable and all clients will
be moved to the leftmost monitor). However, if at least one monitor
isn't plugged in, dwl will still crash the same as before.
Unlike sway, when the output configuration is changed and restored,
(unplug + plug the same monitor for example) previous application
positions aren't kept. This is due to the fact that on sway every
workspace is unique among all monitors.
Compensate the coordinate changes when adding a new monitor.
Every test so far confirms that monitors are always added to the left,
on top of the list, so every floating window's x coordinate has to be
incremented by the width of the new monitor.
When a monitor is created or removed, the geometries of the old ones
must be updated. This is also more efficient than before since we
calculate the monitor geometries only when creating and destroying
monitors. arrangelayers() is needed to recalculate m->w. arrange() is so
clients don't move to the left monitor when plugging or unplugging
monitors (clients keep the same coordinates but the field below them
changes).
