This commit restores the old XCB drawing code paths while keeping the
cairo drawing available via a compile-time switch (I3BAR_CAIRO). This
is necessary as cairo currently has a bug that breaks i3bar for users
without the RENDER extension, which might be the case, e.g., for VNC
users.
For more context, see #1989 and the discussions about its fix. Once the
cairo fix is available in a stable release, i3 can depend on that version
and remove the XCB drawing code paths.
fixes#1989
This commit refactors the i3bar drawing code to also define an abstraction
function for clearing a surface. This is needed to fully abstract i3bar/xcb.c's
drawing code so that we can introduce a switch to easily exchange the
underlying drawing mechanism.
This introduces the flag "--pango" on the mode config directive to
explicitly enable pango markup for mode names. Not setting this will
cause the mode name to be rendered as is.
This fixes a regression in 4.11 where mode names containing characters
such as '<' would break user's configs as they didn't escape these
characters.
fixes#1992
With this patch, the no_focus directive will be ignored if the
to-be-opened window is the first on its workspace as there's no
reason the user would not want to focus it in this case.
This improves usability when, for example, using a tabbed
workspace_layout.
fixes#1987
Since libi3 currently creates its own cairo surface for drawing text, we
need to mark our own surface as dirty to force cairo to invalidate its
cache. Otherwise, this will result in graphical glitches such as the text
not showing up at all.
This wrapper can be removed in the future when libi3 is adapted to reuse
the same cairo surface as we do for all other drawing operations.
We pass alpha channel information to the current text drawing code
and use it if it is available. The previous behavior of using full
opacity for RGB format colors is preserved.
This patch creates all necessary windows for i3bar with 32-bit visuals if available.
It also introduces the possibility to define RGBA colors (next to RGB colors), which
allows the user to set the opacity of any color. This requires running a compositor.
With this patch we also start supporting _NET_SYSTEM_TRAY_VISUAL, which is necessary
for the tray icons so they create the tray window with the correct depth and visual.
1). See the issue #1926. For example, the second keybinding is not detected as a duplicate:
bindcode Mod4+24 sticky toggle
bindsym Mod4+q focus parent
2). To fix it, check duplicated bindings when translating the keysym to keycodes.
