1. Prevent window snapping triggered by mouse from moving the window
into the adjacent output.
2. Make the coordinates used to check whether window snapping is
triggered relative to the output the cursor is at, not the output the
view is belonging to. This allows users to grab a tiled window and move
it into another output or tile it again in another output in a single
drag.
This is a useful (if lesser-known) feature of at least a few popular X11
window managers, for example Openbox and XFWM4. Typically right-click on
the maximize button toggles horizontal maximize, while middle-click
toggles vertical maximize.
Support in labwc uses the same configuration syntax as Openbox, where the
Maximize/ToggleMaximize actions have an optional "direction" argument:
horizontal, vertical, or both (default). The default mouse bindings match
the XFWM4 defaults (not sure what Openbox has by default).
Most of the external protocols still assume "maximized" is a Boolean,
which is no longer true internally. For the sake of the outside world,
a view is only "maximized" if maximized in both directions.
Internally, I've taken the following approach:
- SSD code decorates the view as "maximized" (i.e. hiding borders) only
if maximized in both directions.
- Layout code (interactive move/resize, tiling, etc.) generally treats
the view as "maximized" (with the restrictions that entails) if
maximized in either direction. For example, moving a vertically-
maximized view first restores the natural geometry (this differs from
Openbox, which instead allows the view to move only horizontally.)
v2: use enum view_axis for view->maximized
v3:
- update docs
- allow resizing if partly maximized
- add TODOs & corrections noted by Consolatis
Replace action_str_from_arg() and action_get_first_arg() with
action_get_str().
Two reasons:
- This optimization reduces neither LOC nor amount of work done during
the arguments processing, but requires two additional functions.
- Logging only the first argument of an action creates an illusion that
only one argument was given. Instead of confusing the user just log
the fact that the action is being handled.
Introduce function action_get_arg() and a set of thin wrappers around
it. This function is responsible for finding the argument and checking
it's type, while the wrappers only to do the necessary type casting.
- Connect to wlr_seat_keyboard_state's focus_change event.
- Add view_from_wlr_surface(), which does what the name says.
- Use focus_change event along with view_from_wlr_surface() to update
server->focused_view and set SSD states via view_set_activated().
- Eliminate desktop_focused_view() since server->focused_view should be
reliably up-to-date now.
- Eliminate view_focus/defocus() since we can now just call
seat_focus_surface() directly.
Make desktop_focus_view() always switch to the workspace containing the
view being focused. It doesn't make much sense for an invisible view to
have the keyboard focus.
Also add an optional "raise" parameter to desktop_focus_view(). This
allows the common pattern of desktop_focus_view() + view_move_to_front()
to be reduced to a single function call.
Our current approach to handling the focused/active view is a bit
confusing. In particular, it's hard to be sure when server->focused_view
is or isn't in sync with the real wlroots keyboard focus.
Try to clean things up a bit. In particular:
- Add comments to server->focused_view and desktop_focused_view() to
clarify that they should match, but it's not guaranteed.
- desktop_focused_view() now prints a warning if it detects that
server->focused_view is out of sync. We should keep an eye out for
this warning, and if we see it, try to figure out why it happened.
- For consistency, use only "focus/defocus" as the verbs in function
names rather than "activate". This is a bit arbitrary, but the idea is
that focus is the primary action while the active/inactive state is a
side effect.
- view_focus/defocus() replace view_set_activated() and now update both
focus and active/inactive state, to try to keep them in sync.
- Add comments at view_focus/defocus() to warn against calling them
directly (we should generally call the desktop.c functions).
- desktop_focus_view(NULL) is now forbidden and is no longer handled as
a special case to clear the focus. This was (at least to me) a
surprising behavior and caused trouble when working on another change.
- To maintain existing behavior, desktop_focus_topmost_mapped_view() now
explicitly clears the focus if there are no mapped views.
There should be no behavioral change here.
...<command> argument (but still resolve tilde).
This makes it easier to write sh -c '' constructs without turning labwc
into a shell parser in order to expand environment variables, whilst
respecting single quotes and escaped characters as well as ignoring
subshells syntax like $(foo) and backticks.
Also, fix bug where buffer length+alloc get out-of-sync
When adding the fallback keybinds we add them as string but expect them being an int.
This commit fixes that by using the same parsing routines that are used when parsing
user supplied configuration.

actions: use enum for _ToEdge action
This happens because of two separate bugs:
- The action validation failed to verify the data type of the argument
- When adding the fallback keybinds we add them as string but expect them being an int
This commit fixes the first bug.
Fixes 1ee8715d57
actions: use enum for _ToEdge actions
This also improves the config robustness as invalid edge names will now
prevent the action to be created in the first place and the user gets
notified about the issue.
Make wrap 'true' by default for both GoToDesktop and SendToDesktop,
in order to default to the current behaviour, and to stay consistent
with Openbox behaviour.
Before this patch it was possible to assign an argument with an
existing name to an action that didn't support the given argument.
An example of this is using `direction` for `GoToDesktop`.
This patch now only creates action arguments that are actually
defined for the given action type and logs an error for
unsupported arguments.
The commit also makes sure to always supply the argument name.
This will reduce required checks in other parts of the codebase
in future commits.
Partly fixes: #894
This can be used to better control Virtual Machines, VNC clients, nested
compositors or similar. All keybinds other than ToggleKeybinds itself are
disabled when first called, a 2nd call will restore handling of all keybinds.
