This is an attempt to minimally support autoconfing windows to
different screens on multihead setups.
|
|
Part of the reason for adding headless support in vmon is to
facilitate embedded use cases. These are often incompatible with
anti-tivoization aspects of gplv3.
I am the copyright holder of all this stuff so it's entirely fine
to switch to gplv2. Phil Freeman contributed one trivial patch
(4183fbd), regardless I checked if he had any objections to the
gplv2 switch and he had none.
So here we go, gplv2 all the things.

There needs to be a bunch of this throughout the codebase, but
just doing this spot fix to silence warnings introduced by
subsequent commits... preparatory commit for rmd integration
|
|
Once upon a time names were going to be added, but that never came
to be and at some point that unused member was removed. Turns out
-DTRACE builds have been broken since.

the non-empty focused_desktop having NULL focused_window shouldn't
be possible, but it just happened to me again while playing with
eon's WIP windowed/fullscreen/fillscreen tristate branch.
Though exceedingly rare, it's annoying, so log the bug and don't crash.

This is unfortunately a bit of a large commit, but it's at least
pretty much all on-topic for the generalized "contexts" feature.
Rather than waste time trying to split this further into smaller
commits, I'm just landing it as-is, now that I've lived with the
interaction model long enough to not completely hate it.
I fully expect to revisit this in the future. One TODO item in
particular I'd like to note is "sending" windows to contexts
always creates a new virtual desktop for the sent window in the
destination context. What should really happen is the
destination context should be checked for an empty desktop, and a
new desktop created only when there isn't an empty one to be
reused for receiving the sent window. Note this only affects
non-migrate sends, as migrates (modified by Shift) explicitly use
the existing focused desktop at the destination context.
See the README for more information on how contexts work and
what's different about the interaction model. It's fairly
minimal, most of what you already know how to do should keep
working as-is. The only oddity would be Mos1-s no longer
"shelves" windows, it's now a modifier to turn "migrates" into
"sends", and by itself is a noop now.
Colors used for contexts haven't been refined and are enumerated
in src/context_colors.def.

minor ergonomic improvement; enables plain wrapping of creates or
other relevant object pointers with _mru() calls without
requiring an intermediate storage variable.
|
|
At some point I wanted to support naming virtual desktops, but that
never materialized and I don't find myself wishing it was there.

This adds a direction parameter to vwm_desktop_next{_mru}() and
vwm_win_focus_next(), deprecating _prev() variants in favor of
a vwm_direction_t parameter.
XK_r has been wired up as a modifier for reversing the direction
of actions like Mod1+Tab (window next MRU cycle) and Mod1+Space
(desktop next MRU cycle). So now if you overshoot, simply hold
the "r" key and repeat the operation to go back, much like how
Shift is often used for reversing alt+tab in i.e. Windows.

When the shelf isn't the currently focused context but the focus
next is relative to the focus context the mapping manipulation
shouldn't be performed.
This would cause unexpected appearance of shelved windows in a
virtual desktop should a shelved window become invisibly unmanaged.
Simple way to repro is to shelf an mplayer window. When the movie
finishes, if you're on a desktop, out of nowhere the next shelved
window appears but you're not supposed to be looking at the shelf.
A simple visit to the shelf then back to the desktop would undo the
anomaly, but it's trivial to fix - hell there was already a FIXME/TODO
sitting there.

Previously only windows fitting the screen dimensions @ assimilate
would become automagically "allscreened". Newer mplayer seems to
break this heuristic, so expand the application of the heuristic
to include configure requests as well.

Use VWM_TRACE_WIN() and add a trace for when we try manage an xwin.
|
|
vwm_win_focus() previously simultaneously told the X server to set the
input focus on the window (if mapped) and set the internal vwm state of
the window to focused.
These are really two separate operations:
1. request the X server to focus the window
2. change vwm's concept of the currently focused window
Since clients can call XSetInputFocus() as well, there's need for doing
step 2 discretely in response to FocusIn events.
Nothing is functionally different after this commit, it just exposes
step 2 as a separate vwm_win_set_focused() function for a future commit
to leverage in handling of FocusIn events.

|
|
Rather than setting this configuring flag for the sake of
vwm_screen_is_empty() to ignore, simply supply the xwin to ignore if
desired.

In the course of applying the new style over the rest of the code I
decided it's obnoxiouos and prefer the old way of indenting the cases
one level from the switch. I know it wastes horizontal space and can
see the value of flattening the cases with the switch, but once you
start having variables at the start of the switch body, and blocked
cases, it just starts becoming quite unattractive without the indentation.
|

Eliminate some 0/NULL initializations.

This member reflects if the window is mapped from the client's perspective,
not necessarily if the window is currently mapped (since vwm maps and unmaps
windows the client has mapped in the course of providing virtual desktops)
Changing the name for better clarity, since it's a bit ambiguous as-is.
|

Long overdue tidying of the map request handling.
This moves all the window classifying and placement stuff into a separate
helper, adding a call to that in vwm_win_manage_xwin(), where this always
belonged.
The map request handling now just manages windows that aren't already
managed, then lets the usual "is this window mapped?" logic filter the
map request.
This should fix a lingering bug where a window on the unfocused desktop
would become spuriously visible if the client mapped it. Firefox started
doing this recently when a page finished loading.

We can assume (vwm->focused_desktop != NULL), the initial desktop
is created early in startup and the last one can't be destroyed.

I'm no longer fond of combining one-line conditional statements on
the same line as their conditional expression.
|
|
|
|
Long overdue house cleaning.
The addition of compositing/monitoring overlays in vwm3 pushed vwm well past
what is a reasonable size for a simple thousand line file. This is a first
step towards restoring sanity in the code, but no behavioral differences are
intended, this is mostly just shuffling around and organizing code.
I expect some performance regressions initially, follow-on commits will make
more improvements to that end as the dust settles.
