Re-introduce fully-fledged get_colorpixel function, which enables arbitrary
color depths for the display. The previous code is kept as an optimization for
the case of a true color display, where a X11 roundtrip is unnecessary.
Corrects the cases where the colorpixel is not 0xRRGGBB : we have to
use the full color_t struct to describe font colors, as Pango expects
RGB values and not an XCB colorpixel value.
According to the User's Guide [1], an `assign` command allows a
`workspace` token after the selector, as an alternative or in addition
to the unicode arrow `→`. In reality, however, the `workspace` token is
not recognized.
Example:
assign [class="Firefox"] workspace "1: Browser"
should assign Firefox windows to workspace `1: Browser`, but the the
browser window appears on a new workspace called
`workspace "1: Browser"` instead.
With this fix, both `→` and `workspace` are recognized (and ignored)
after the selector.
[1] https://i3wm.org/docs/userguide.html#_automatically_putting_clients_on_specific_workspaces
We now execute the validations when "kill" is executed even if match
criteria are used. This prevents users from killing workspace containers,
which instead kills all clients (as before when not using criteria).
fixes#1761
It should be clear for callers of this function that this is an internal
function that skips certain validations which might be important. Therefore
we make it clear that this is an internal function by renaming it.
relates to #1761
We need to move the urgent flag when moving a container across
workspaces before calling on_remove_child on the parent in order
to avoid a crash.
fixes#2128
Even if the X11 root window cursor is not set up correctly for some
reason, with this fix, users should at least see the correct cursor when
the pointer is over i3bar.
see issue #2114
This fixes race conditions, for example when i3bar gets reconfigured
after the available outputs change. In that specific case, i3bar sends a
ConfigureWindow request (see
b5693d6fb3/i3bar/src/xcb.c (L376))
which normally is turned into a ConfigureRequest that i3 largely
ignores, only the dock client’s height is considered (see
b5693d6fb3/src/handlers.c (L390)).
Turning ConfigureWindow into ConfigureRequest is only done when the
SubstructureRedirect event mask is set, and because we temporarily
removed _all_ events from our mask, the ConfigureWindow request went
through unmodified.
This in turn lead to the i3bar client window (not its decoration frame)
being positioned at e.g. y=1304, whereas dock client windows should
always end up at x=0 y=0 within their decoration frame. The result of
the i3bar client window being out of the visible space was either a
black i3bar or graphics corruption.
This also fixes issue #1904, I think. I couldn’t reproduce issue #1904
specifically, but when i3bar is in the misconfigured state, it will
receive a VisibilityNotify event, telling i3bar that it is obscured.
This would explain why i3bar sent a SIGSTOP in issue #1904.
fixes#1904
Previously, if a match specification contained the con_id or con_mark criterion,
all other criteria were ignored. However, a user may want to specify one of
those two unique identifiers and still specify others as well, for example to
match the currently focused window, but only if it has a certain WM_CLASS:
[con_id=__focused__ class=special] kill
We now check all specified criteria.
fixes#2111
This commit fixes#1969 by adding support for matching a window's type
against _NET_WM_WINDOW_TYPE_NOTIFICATION. The userguide and tests were
updated to reflect this change.
Previously, mouse bindings could only be run when a window was present,
by using --whole-window. Such bindings would not work on empty
workspaces. However, this is a valid usecase for bindings like
bindsym $mod+button4 workspace prev
bindsym $mod+button5 workspace next
Hence, we need to grab the root window as well and run bindings on it.
fixes#2097
Previously, using a command like
[con_id=foo] kill
would kill the currently focused window because while an error for
not being able to parse the con_id was logged, no further action
was taken, which caused the criterion to be ignored. In this case,
the fallback behavior of using the focused window took over.
For con_id, id and window_type we now reject incorrect values with
an error and abort the command.
fixes#2091
We now only log an error but do not exit when creating the graphics
context fails. While, if this happens, rendering will likely be wrong,
this is still better than terminating the user's session entirely due
to a rendering problem, potentially causing data loss.
relates to #2094
The values of a Rect are unsigned, but can contain signed values.
Using MAX when the value is negative causes incorrect behavior and
makes the result stay negative, which is what we wanted to avoid here
in the first place.
Fix by properly casting the value for the comparison.
fixes#2094
If a window with border is set to "border none" and then closed, we would
call cairo_destroy / cairo_surface_destroy twice, causing an assertion
failure in cairo as the objects already had zero references the second
time. We fix this by explicitly setting these objects to NULL.
relates to #1278
With this patch, we use 32-bit visuals per default whenever it is
available. Otherwise, we fall back to the actual root window's
depth, which will typically be 24-bit.
Before this patch, we already used 32-bit depth for containers with
a window that uses 32-bit. However, this means that we didn't use
32-bit for split parent containers on which decoration is drawn.
For 32-bit windows using transparency, this caused a graphical glitch
because the decoration pixmap behind it would show through. This
behavior is fixed with this change.
relates to #1278
Such containers never require a pixmap anyway. In particular for the __i3
output (used for the scratchpad workspace), this would cause an allocation
error anyway because it can be very big -- so big, in fact, that X cannot
allocate the pixmap for it.
Until now, this error was silently ignored due to the fact that we did not
create the pixmap checked (and asserted its success), but with cairo this
would cause a crash because we'd try to create a surface for a pixmap
which doesn't exist.
relates to #1278
With this patch we remove the temporary draw_util_colorpixel_to_color
function we introduced previously by parsing the colors as color_t to
begin with.
relates to #1278
We return early from drawing functions if the surface to draw to is not
initialized properly. There is no immediate need to do so, at least no
crashes have been observed, but it mirrors the previous behavior a bit
more closely. Furthermore, i3 should not crash due to not being able to
make some rendering call, so this provides some stability.
relates to #1278
This patch migrates all decoration rendering of i3 to cairo. Using the
compile switch CAIRO_SUPPORT, rendering can be switched back to the
previous XCB behavior, just like with the previous migration to cairo
in i3bar.
This patch also fixes a bug in draw_util.c where copying one surface
to another would use incorrect coordinates if the source coordinates
are not 0, 0.
Furthermore, this patch implicitly fixes some minor issues in the
decoration rendering which would be ignored previously due to the fact
that errors would only show up in the event queue, but not cause the
rendering code path to crash. One example is zero-height pixmaps which
are not allowed. Using cairo, these would cause i3 to instantly segfault,
so this patch avoids this.
Lastly, this patch annotates other issues found but not fixed in this patch
using TODO comments, e.g., the zero-height check not working correctly
and the comment that it should probably work the same way for zero-width
pixmaps.
relates to #1278
This patch fixes a bug when copying one surface to another.
Since it only exposes itself when used with non-trivial source
coordinates, it didn't surface before when only used for i3bar.
relates to #1278
In order to prepare for using cairo for rendering i3 decorations,
we need to make the draw_util.c from i3bar available via libi3 such
that both i3bar and i3 can use it.
