This was temporarily removed when introducing proper view abstractions.
Now that we have the cg_xwayland_view struct, we reintroduce this
workaround in its proper place.
This also fixes the previous workaround, which checked whether a view
was *currently* mapped and not if it *has ever* been mapped.
See #18, #19 and 443d955dfd.
When using the Wayland or X11 backend, Cage is drawn inside a window.
This commit sets this window's title to that of the currently focused
toplevel window inside Cage.
Fixes#29.
This is to work around "misbehaving" (for lack of a better term)
clients. At the moment, Firefox Nightly and Google Chrome/Chromium are
known to be suchs client:
When XWayland support is enabled, Firefox first creates an XWayland
surface, closes this (before mapping it) and then opens an XDG toplevel
surface. Cage tries to manage the first XWayland surface, but when it
closes, Cage has no surfaces left and hence closes as well.
Hence, Cage terminates before it picks up on Firefox's XDG toplevel, and
Firefox (rightly) prints it cannot read the Wayland pipe.
In Chromium's case, it simply opens an XWayland surface which it
immediately closes, before opening the "real" XWayland surface.
The workaround is to track whether an XWayland surface has been mapped
and, if it hasn't, to not exit when we have no views left.
Firefox's behavior and the workaround are discussed in #18.
This commit fixes#18 and is part of the fix for #19.
This is the path we settled on in #24.
That is: any new toplevel window takes over the Cage display, hiding any
previous toplevels until it is closed. Only when the last toplevel is
closed, does Cage exit as well.
This allows us to check per-view whether is has dialogs open, instead of
diong it on a global basis as we are doing currently. This is necessary
for fully supporting multiple primary clients.
With this, some apps (e.g. mpv) can block the idle tracker from
kicking in. This way, the screen won't blank (or whatever you
configured) when the application doesn't want it to.
