- 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.
these should only be set on commit. doing so before then confuses
code that expects these fields to be in sync with the scene tree,
such as `handle_commit`.
these were only being set so that `view_center` could read them to
compute a centered position, so instead we can simply forward the
values directly to `view_compute_centered_position` and `view_move`.
- Store a pointer to the `struct view` in `struct ssd`
- Pass `struct ssd *` instead of `struct view *` to ssd functions
- Add `ssd_get_margin()` convenience function
If `view->ssd_enabled` is false when calling `ssd_create()` then
`ssd_thickness()` returns zeroes which are stored in `ssd->margins`.
The quick fix is just to ensure we set `view->ssd_enabled` before
calling `ssd_create()`. At some point, it might be nice to refactor
so that `ssd_create()` does not reference `view->ssd_enabled`.
- Minimize includes in `ssd.h`
- Avoid repetitive `view->ssd.margin` pattern
- Use `struct ssd *` or `const struct ssd *` rather than `struct view *`
where convenient
Part of the motivation is to make it easier to separate `struct ssd`
from `struct view` in a future commit.
- Add `active` argument for consistency with `ssd_set_active()`
- `assert()` that `ssd_create()` is not called twice without an
`ssd_destroy()` in between
Gather related logic from `reload_config_and_theme()` in `server.c` and
`ssd_reload()` in `ssd.c` into a new function, `view_reload_ssd()`.
Also drop the `view->mapped` check since we want to update any view that
has SSD nodes created, mapped or not.
`view_set_decorations()` now calls `ssd_create()` and `ssd_destroy()`
explicitly to enable/disable decorations. As a result, the implicit
enable/disable logic in `ssd_update_geometry()` is no longer needed.
Add xdg_surface_from_view() + xwayland_surface_from_view() accessors
that assert() the view is of the expected type before returning.
Fix a real bug in xdg.c parent_of() that dereferenced
`view->xdg_surface->toplevel` without first checking `view->type`.
The goal of the new accessors is to catch similar bugs in future.
IMHO it encourages better design (by making dependencies more obvious)
to have source file/header file pairs like view.c/view.h, rather than a
monolithic header like labwc.h with everything in it.
I don't think we need to break up all of labwc.h at once, but maybe we
can start pulling it apart bit by bit as it's convenient.
Also:
- Move "struct border" to ssd.h so that view.h can use it without pulling
in all of labwc.h.
- Add a missing required #include within scaled_font_buffer.h (forward
declaration of "struct font" is not enough).
Currently, snapping to a screen edge and then snapping to maximize
results in both the natural_geometry and tiled state of the view
getting messed up. After unmaximize, the view ends up in a weird
state (tiled location but natural/untiled size).
There are also a couple of sketchy things going on in the code:
- interactive_begin() pokes its own values into view->natural_geometry
to force view_maximize() to set a particular geometry.
- interactive_end() "fixes" view->natural_geometry after calling
view_maximize() to save the original geometry from the start of the
interactive move/resize.
To fix all this:
- Adjust/expand the API of view.c so that the interactive.c can
avoid this "back door" of overwriting view->natural_geometry
directly.
- Save the natural geometry and the tiled state of the view in
interactive_begin() when starting to move the view. When done,
interactive_end() will update the tiled state if appropriate but
*not* overwrite the natural geometry.
On initial positioning of toplevel windows we call view_center().
During the centering process, if it turns out that the view is larger than
the output usable-area then we just top/left align it with no gap.
Relates to the gap aspect of issue #403
