Instead of stashing the active view and setting Seat.focused to the
Xwayland OR surface when a child OR surface of a currently focused
Xwayland view is given keyboard focus, keep Seat.focused set to the
Xwayland view.
Such Override Redirect surfaces are commonly used for drop down menus
and the like, and river should behave as if the parent Xwayland view
still has focus.
This ensures that the riverctl focus-view next/prev commands continue to
work as expected while a popup is open, the correct focused view title
will be sent over river status, etc.
It's also cleaner to centralize this logic in XwaylandOverrideRedirect
and keep it out of Seat.zig.
Xwayland OR menus may disappear if their parent view is deactivated. The
heuristic and ICCCM input model implemented prior, used to determine whether an
OR surface may take focus, does not cover all menus, so retaining parent view
activation works as a catch-all solution for handling unwanted OR menu focus.
Adding the set_override_redirect listener on creation and removing it
on destruction was missed when implementing override redirect state
change handling.
I have encountered a crash (failing assert) if a view specified a fixed
size less than this minimum, and according to ifreund this behavior was
planned to be removed, anyway.
In particular, this fixes a crash that can happen if a client is made
non-fullscreen and then, while that transaction is ongoing, made
fullscreen again.
Currently the view destruction sequence is started as soon as a view
is unmapped. However, this is incorrect as a client may map the view
again instead of destroying it.
Instead, only start the view destruction sequence when the underlying
xdg toplevel or xwayland surface is destroyed.
This extends the `float-filter-add` command to allow matching on window
titles as well, using a `float-filter-add kind pattern` syntax. The
following kinds are supported:
* `title`, which matches window titles
* `app-id`, which matches app ids
Only exact matches are considered.
As an example following configuration floats all windows with the title
'asdf with spaces'.
riverctl float-filter-add title 'asdf with spaces'
Currently if a view is mapped while some other view is fullscreen, it
will not be added to the focus stack, which means that if the fullscreen
view is then closed the view which was not added to the focus stack will
not be focused.
To fix this, always add views to the focus stack on map.
The view.unmap() call may synchronously destroy the view, which makes
the the code removing listeners which is currently run after
view.unmap() access free'd memory.
To fix this, simply change the order of the calls to match that of
XdgToplevel.handleUnmap().
The transaction system exists to coordinate size changes of all views
in a layout in order to achieve frame perfection. Since many clients
do not need to commit a new buffer in response to a activated state
change alone, this breaks things when such a configure event is tracked
by the transaction system. Instead, simply send activated and fullscreen
configures right away but still track this state in a double-buffered
way so that e.g. border color changes based on focus are frame-perfect.
This also fixes a related issue with the transaction system where views
that did not need to commit in response to our first configure were not
rendered until their next frame.
- Double buffering focus state ensures that border color is kept in sync
with the transaction state of views in the layout.
- Using a counter instead of a bool will allow for proper handling of
multiple seats. This is done in the same commit to avoid more churn in
the future.
