The wlroots wlr_output_layout provides two different modes of operation:
- automatically
- manually
In automatic mode wlroots reacts to new / removed outputs and resolution
changes and then adjusts the output positions within the layout itself.
The manual mode disables this behavior and thus it is the whole
responsibility of the caller (e.g. us relaying whatever wdisplays /
kanshi provides) to ensure that the layout is somewhat sane. E.g. that
it doesn't have any holes between outputs and there are no overlapping
outputs.
The mode is set for each output individually. To use (and keep using)
the automatic mode, outputs have to be added via the _add_auto() variant
(which we do) and they are not allowed to be moved via _move() (which
we currently do and thus break the automatic layout).
To fix that, this patch compares the user (tool) supplied position to the
automatically calculated position and only if they differ we call _move().
- Process layer-shell keyboard interactivity in the map and commit
handlers only, rather than in layers_arrange(). This allows handling of
the layer-surface that emitted the event rather than iterating over all
surfaces in the output layer-tree, and therefore avoids having to guess
which surface should have keyboard preference (and it might not be the
last one added to the list which was the assumption previously).
- Prevent seat_focus_surface() from setting keyboard focus if a layer-shell
surface with exclusive keyboard-interactivity has the focus.
- Set cursor_context type for layer-surfaces without node-descriptors
in order to set keyboard focus correctly in cursor_button_press().
Tested satisfactorily with xfce4-panel and gtk-layer-demo.
Fixes#725 and #704
- Move xwayland-specific struct definitions to new xwayland.h header
- Move xwayland_move_sub_views_to_front() from desktop.c to xwayland.c
- Split out xwayland_server_init/finish() from server_init/finish()
- Rename new_xwayland_surface -> xwayland_new_surface and
xwayland_surface_new() -> handle_new_surface() for consistency
- Add "mapped" argument to xwayland_unmanaged_create() so that we can
make unmanaged_handle_map() private to xwayland-unmanaged.c
This restores the original approach of naming the argument `layout_changed`
which fits much better than `enforce_view_arrange`. Especially when extending
the function to also handle region updates once merged.
Move the desktop_arrange_all_views() call outside layers_arrange() into
a new function, output_update_usable_area(). The new function currently
does exactly what layers_arrange() used to, but will be expanded in a
later commit.
Add output_update_all_usable_areas(), which is the same as calling
output_update_usable_area() for each output, but only calls
desktop_arrange_all_views() once.
Rebased and slightly modified by @Consolatis
...by reading <config-dir>/themerc-override where <config-dir> is normally
$HOME/.config/labwc can be other locations as described in labwc-config(5)
and can also be specified by the command line option -C.
The reason for supporting theme override is to give users more fine-
grained control of settings without making local copies and modifying
themes.
Before this patch following would cause a use-after-free:
- calling the Debug action when there was at least one view around
- closing that view
- calling the Debug action again
Also add a label for the layer popup tree.
