For example, variables:
`theme->window_inactive_border_color`
`theme->window_active_border_color`
are converted to:
`theme->window[THEME_INACTIVE].border_color`
`theme->window[THEME_ACTIVE].border_color`
The iterator value of `wl_list_for_each` should never be referenced
outside the loop because it points to invalid memory location when the
list is empty.
The rounded mask buffer to be applied to the corner button buffer should
be resized and shifted when there's a vertical gap between the button
and the window border.
...to replace padding.{width,height} to minimize breaking changes with the
visual appearance of the titlebar.
With the diverging labwc specification for the titlebar (listed below)
we have to choose between (a) not supporting the padding.{width,height}
option which exist in many extant Openbox themes to keep titlebar height
(almost) the same; or (b) making the allocated button areas much smaller
and not keeping the default hover going all the way to the edges. All in
all it just seems a lot simpler and cleaner to break this link to the
openbox spec.
Examples of previous change driving the requirement for this change:
- SVG and PNG support which often results in large icons with hover
effects.
- Theme option window.button.{height,width}
- Larger default areas for icons (26x26)
In way of an example, Numix theme sets a padding.height of 6 which would
have resulted in a titlebar 12px taller without this change.
...because now that window.button.height determines the height of button
hover effect the visible appearance of the titlebar will change unless
we reduce the padding to zero.
Backward compatibility notice: If a users theme sets padding.height to a
value greater than zero, the titlebar will be taller compared with
openbox. This can be fixed by either reducing window.button.height or
overriding padding.height
This theme setting does not exist in Openbox spec and has just been an
additional 'knob' to tweak the height which is otherwise derived from the
sizes of the objects within it plus padding.
window.button.{height,width} determine the space allocated for buttons.
Buttons can be smaller than this size and will then just be center aligned
within the allocated space. However, buttons will be clamped at this size
to prevent them from going outside of the allocated space.
- Add a new function to get the maximum scale of all usable outputs
- Pass the maximum output scale through to img_svg_load(), which
ultimately calls cairo_surface_set_device_scale() before rendering
Add buffer_adopt_cairo_surface(), which allows wrapping an existing
cairo image surface in a struct lab_data_buffer. This is useful when
loading PNGs since most will be loaded as ARGB32 already.
Fix a memory leak in the non-ARGB32 PNG case, where we do still need to
paint to a new image surface -- we were leaking the original surface.
Eliminate an unnecessary temporary image surface in SVG loading and just
render the SVG to the image surface held by the lab_data_buffer.
I also cleaned up and clarified the buffer API a bit:
- Add a pointer to the held cairo_surface_t (so we can still access it
if there is no cairo_t).
- Remove the free_on_destroy bool (it was always true).
- Rename unscaled_width/height to logical_width/height and add an
explanatory comment. It was unclear what "unscaled" meant.
- Rename buffer_create_wrap() to buffer_create_from_data().
This is laying groundwork for some more icon fixes I am working on
(making sure icons are loaded and rendered at the correct scale).
- The builtin hover effect is now unrounded when the window is tiled.
- All the corner button icons including ones provided by the user are
now rounded when the window is not tiled.
- Fixed the bug that the window menu button as a fallback of the window
icon is not correctly rounded.
The hover icon buffer on which the hover overlay is draw can be larger
than the button size when a large non-hover icon is provided by user. In
this case, we should scale up all the coorinates that are used to draw
the hover overlay. Before this commit, corner radius and padding.width
are not scaled correctly.
This commit fixes it by scaling the cairo context with cairo_scale()
when drawing the hover overlay.
The default `titleLayout` is updated to `icon:iconify,max,close` which
replaces the window menu button with the window icon.
When the icon file is not found or could not be loaded, the window menu
icon as before is shown.
The icon theme can be selected with `<theme><icon>`.
This commit adds libsfdo as an optional dependency. `-Dicon=disabled` can
be passsed to `meson setup` command in order to disable window icon, in
which case the window icon is always replaced with a window menu button.
...defined by `<separator label="">`.
Also add the theme option `menu.title.bg.color: #589bda`
The following will be added in separate commits
- menu.title.bg.border.color: #7cb6ec
- menu.title.text.color: #ffffff
- menu.title.text.justify: center
This adds a screen magnifier which can be controlled with the
`ZoomIn` / `ZoomOut` and `ToggleMagnify` actions.
It scales up part of the rendered framebuffer so the magnification
may end up looking blurry depending on the magnification scale.
PR #1774
Add optional drop-shadows to windows using server-side decoration.
Shadows can be enabled/disabled rc.xml and their appearance configured
in themerc. The default is no shadows to preserve current behaviour.
The shadows are drawn in fixed corner and edge buffers shared between
all windows, the edges are scaled to size depending on the size of each
window. Two sets of buffers are used to give the different appearances
for active and inactive windows. I use separate corner/edge buffers for
a few reasons:
- It avoids needing to store a separate large shadow buffer per window
- It avoids needing to redraw the shadows when the window is being
resized
- Compositing the shadows onto the desktop should be faster as there are
overall fewer pixels to blend, and scaling up the edge buffers only
requires reading a tiny buffer which is then replicated.
Filled/outlined rectangles shown as snapping overlay are now enabled/disabled
independently with `snapping.overlay.[region|edge].bg.enabled` and
`snapping.overlay.[region|edge].border.enabled`.
To keep the default behavior, `*.bg.enabled` is yes and `*.border.enabled` is
no for hardware-based renderers, while `*.bg.enabled` is no and
`*.border.enabled` is yes for software-based (pixman) renderer.
Users can now use a filled rectangle as an overlay even with pixman renderer.
However, this may severely impact performance when used with translucent
`snapping.overlay.[region|edge].bg.color`.
This commit includes a refactor to use substruct `theme_snapping_overlay`
inside `theme` in order to pass it to `create_overlay_rect()` in a cleaner way.
Breaking changes is:
- `snapping.overlay.[region|edge].fill` is now removed.
Replace "preview" in rc.xml and themerc with "overlay" since "preview" sounds
like it shows the window content.
Breaking changes are:
- `snapping.preview.*` in themerc is now replaced with `snapping.overlay`.
- `<snapping><preview>` in rc.xml is now replaced with `<snapping><overlay>`.
Add ability to set width with percentage of monitor instead of just pixels.
With this the OSD sizes itself properly on both my 4k and 2k monitors.
example: 50% or 75% instead of 600, max 100%
wlr_scene_rects expect their color to be pre-multiplied
while cairo_set_source_rgba() expects them to not be
pre-multiplied. With this patch we now use premultiplied
colors internally by default and then reverse it when
setting cairo colors.
This ensures the titlebar uses a consistent color in case
it was defined with some transparency by the user.
