Two types of window rules are supported, actions and properties. They are
defined as shown below.
<windowRules>
<!-- Action -->
<windowRule identifier="some-application">
<action name="Maximize"/>
</windowRule>
<!-- Property -->
<windowRule identifier="foo*" serverDecoration="yes|no"/>
</windowRules>
Rules are applied if windows match the criteria defined by the
'identifier' attribute which relates to app_id for native Wayland windows
and WM_CLASS for XWayland clients.
Matching against patterns with '*' (wildcard) and '?' (joker) is
supported.
Add 'serverDecoration' property.
view_minimize() does not need to call desktop_move_to_back() because the
stacking order is not changed and the windowSwitcher uses the scene-tree
nodes anyway.
Note: Movement of xwayland sub-views still relies on keeping server->views
in sync with z-order
- Make view_discover_output() static
- Call view_discover_output() only for floating views
- Deprecate view_output(); make it use view->output when possible
A fullscreen view currently has its output specified twice by:
- struct output *output
- struct wlr_output *fullscreen
view->fullscreen may also become a dangling pointer if the output is
disconnected, because view_on_output_destroy() clears view->output but
not view->fullscreen.
To eliminate the redundancy and the dangling pointer, let's change
view->fullscreen to a Boolean and rely on view->output to specify the
output.
Along the way, change a few related usages of struct wlr_output to
struct output as well.
No functional change intended.
v2: Don't allow entering fullscreen on disabled output (makes
conditions for entering/leaving fullscreen symmetric)
v3: Use output_is_usable() helper
view->impl->move() is a specific case of view->impl->configure().
To reduce code duplication, we can use view->impl->configure() for
pure moves (without resize) as well.
xwayland's move() function also possibly contained a race condition
when there was a pending resize, as it used the current surface
width/height rather than the pending width/height. This is fixed.
It was not working before because in the case of wayland
we are only dealing with sizes as wayland has no notion
of a global position. A wayland client would thus not
necessarily respond to a configure request which sets
the same size again. This causes us to also not apply
a new position set in view->pending because there may
be no commit from the client in those cases.
We previously worked around this issue in some parts
of the code to check our new sizes against the pending
ones and if they were the same we would call view_move
instead. That had two issues:
- Not all parts of the code did that which could end up
delaying the positioning either to the next completely
unrelated xdg commit event or to the next view_move call
- The code started to repeat itself, e.g. the same condition
with calls to either view_move or view_move_resize based
on the result
This patch fixes it by doing the check in the xdg configure
handler instead. Xwayland is unaffected by this issue as we
are always configuring a xwayland client with both, position
and size.
- 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
Before this patch following would cause the SSD to be rendered offscreen:
- snap a window to left or right edge
- toggle fullscreen to fullscreen
- toggle fullscreen to un-fullscreen
To fix that restore the SSD before calculating the new geometry.
