Ignore any further xdg_output events. Name and description are constant
for the lifetime of wl_output in xdg-output-unstable-v1 version 2 and we
don't need other properties.
Fixes#990.
Add additional fields, namely `source_volume` and `source_desc`
Add `tooltip-format`, reverting to default behavior if not specified
Add additional CSS classes, namely `sink-muted` and `source-muted`
Destroy request is not specified for foreign toplevel manager and it
does not prevent the compositor from sending more events.
Libwayland would ignore events to a destroyed objects, but that could
indirectly cause a gap in the sequence of new object ids and trigger
error condition in the library.
With this commit waybar sends a `stop` request to notify the compositor
about the destruction of a toplevel manager. That fixes abnormal
termination of the bar with following errors:
```
(waybar:11791): Gdk-DEBUG: 20:04:19.778: not a valid new object id (4278190088), message toplevel(n)
Gdk-Message: 20:04:19.778: Error reading events from display: Invalid argument
```
This error occurs because of an incorrect assumption that the size of
the list of nodes that contains the focused window is the number of
windows in a workspace.
The windows in a workspace are stored as a tree by Sway, rather than a
list, so the number of windows has to be found by counting the leaves of
a workspace tree.
GDK Wayland backend can emit two events for mouse scroll: one is a
GDK_SCROLL_SMOOTH and the other one is an emulated scroll event with
direction. We only receive emulated events on a window, thus it is not
possible to handle these in a module and stop propagation.
Ignoring emulated events should be safe since those are duplicates of
smooth scroll events anyways.
Fixes#386
Previously we only checked when connecting to the server whether it had
the minimum required version but didn't act accordingly in the various
functions that use the functionality of later versions. If there were a
server in the wild, that actually would not have this functionality,
there would have been a crash. Fix this by checking the version before
using the functionality and gracefully abort it.
