Adds `output` attribute to control which monitor(s) display the window
switcher OSD. Supports three modes:
- "all": display on all monitors (default)
- "pointer": display on monitor with mouse cursor
- "keyboard": display on monitor with keyboard focus
The configuration structure is also refactored to nest OSD-specific
settings (show, style, output, thumbnailLabelFormat) under an <osd>
element within <windowSwitcher>, improving logical organization.
The previous "minimal fix" (5148c2aa31) worked but was a bit of a
hack, as it basically un-minimized and then immediately minimized the
view again at map. It's not actually too difficult to make the map
handlers aware of minimized views, eliminating the need for the hack.
Note: this depends on the previous commit ("xwayland: connect commit
and surface_destroy handlers together") otherwise the xwayland map
handler registers the commit handler twice, leading to a crash.
Factor out set_surface() which consolidates connecting/disconnecting
the wlr_surface event listeners in one place.
In theory, this means we can receive commit events for minimized views.
However, with a test app that resizes itself, I didn't see any change,
i.e. the commits still don't come through until un-minimize. It's
possible they are being filtered at wlroots or protocol level.
Also remove an old, semi-related TODO from view.c.
It's possible for a fullscreen xwayland view to be unmapped without
being destroyed. In this case, we need to update top layer visibility,
otherwise panels and the like will remain hidden.
Since unmap is always called before destroy, it's sufficient to do the
update only in view_impl_unmap() and not in view_destroy().
Adaptive sync logic needs work still, but I tried to minimize changes
to it since I don't have hardware to test it.
This commit adds `<windowSwitcher thumbnailLabelFormat="%T">` to configure the label text in each item in the thumbnail-style window switcher. Its format follows `<fields><field content="custom" format="">`.
This allows us to share common codes for dealing with osd items.
For example:
- Get the clicked osd item to focus its associated window
- Scroll the items when their total height is taller than output height
Before this commit, output transformations were not taken into account for
parcent-based osd widths like:
osd.window-switcher.style-classic.width: 80%
osd.window-switcher.style-thumbnail.width.max: 80%
Removing newlines in rc.xml and menu.xml caused parser error with
following content:

...though it is a valid XML.
Let's not do that. I moved `grab_file()` to `buf.c` and renamed it to
`buf_from_file()`, because it now directly touches `struct buf` and
I don't like having a source file only for one function.
The if-statement doesn't make sense, because `view_get_string_prop()`
never returns NULL. And if it did, it would cause segfault in
`osd_thumbnail_update()`.
This commit adds new theme options:
- osd.window-switcher.style-classic.item.active.border.color
- osd.window-switcher.style-classic.item.active.bg.color
These theme options configures the border/background of selected window
item in the `classic` style window switcher. Their default values are
identical to `thumbnail` style window switcher, which means the default
border color is now `osd.label.text.color` with 50% opacity and the
default background color is now `osd.label.text.color` with 15% opacity.
In 2ac4811, I was missing that windows can be tiled to "center".
As a result, after executing
`<action name="SnapToEdge" combined="yes" direction="left" />` against a
center-tiled window, `view->tiled` is set to `CENTER|LEFT`.
Previously, the default values of
`osd.window-switcher.style-thumbnail.item.active.{bg,border}.color`
were blue. But they caused the selected window title in the window
switcher to be unreadable due to duplicated colors of the text and
background with Openbox themes like Numix.
Instead, this commit updates them to follow other themes configurations.
The default border color of the selected window item is now
`osd.label.text.color` with 50% opacity and the background is
`osd.label.text.color` with 15% opacity.
For subpixel antialiasing to work, the background color is calculated by
manually blending `osd.label.text.color` and `osd.bg.color`, rather than
just updating the alpha with 50% or 15%.
