Desktops (workspaces) support

[sagb]

Current goal of master (release) branch: full desktops support.
Current strategies:
-1 desktop: switch to any desktop, including -1 (as for i3), except in cwm.

The following madness must be taken into account:

lwm (#40):
number of desktops: 1
current desktop: 0
window's desktop: _NET_WM_DESKTOP or _WIN_WORKSPACE aren't set.

cwm (#35):
number of desktops=10
active desktop=1
window's desktop=-1 (_NET_WM_DESKTOP(CARDINAL) = 4294967295)
group membership switched by ctrl-alt-g (man openbsd-cwm),
-1 means "isn't member of any group"

i3 (#45):
number of desktops: 1
current desktop: 0
normal window's desktop: 0
window on hidden desktop aka "scratchpad": -1 (_NET_WM_DESKTOP(CARDINAL) = 4294967295)
Unlike cwm, -1 does indeed mean something.
Also, scratchpad window has:
WM_STATE(WM_STATE):
window state: Withdrawn

A comment in wmctrl:
/* special desktop ID -1 means "all desktops", so we
have to convert the desktop value to signed long */
also see "sticky window" in man
-d 2 for "sticky windows always shown" or "-1 desktop always shown"?

EWMH switching issues basically fixed (#45).

I'm noticing this today in i3:
When I have a workspace that's not visible, and on that workspace there are stacked windows, such that window X is in front of window Y. If I use Alttab to switch to window Y, it takes me to the correct desktop, but it does not raise window Y, which is still behind window X.

I'm not sure what do you mean by invisible workspace. Could you point to the specific section in https://i3wm.org/docs/userguide.html ?

[eater]

I just meant: I have 5 workspaces and 2 monitors. So only 2 workspaces are visible at a time on those monitors. The other 3 workspaces are not visible.

I can't reproduce this. I did the following:

run alttab -d 1
i3-msg 'layout stacking'
opened some windows, they appear stacked
switched to another workspace ($mod-number), opened some windows there
pressed alt-tab and switched to arbitrary window on stacked workspace

Every time this procedure switches desktop, brings correct window at the front and focuses into it.

I'll let you know if I'm able to reproduce it again -- seeming fine today.

Desktop related features considered stable in 1.3.0 released.
