Port the search results list to GtkListview. Use bindings to set
the title, icon, and subtitle of each row. Remove GcalSearchHitRow
as it's unused now.
This reworks the style of the event widgets to make them match the
latest designs. This also supports the light and dark theme preferences
and fixes some spacing inconsistencies and errors.
- The orientation of events only affects how their content is laid out,
not their style.
- Events are fully colored accordingly to their calendar's color.
- Timed events have a semi-transparent background and a kind of opaque
knob on their left.
- Timed events have their text colored according to the theme.
- Lasting events are fully opaque, with no knob.
- Lasting events have their text colored according to their calendar's
color.
This purposefully leaves the indentation broken to help reviewing the
changes.
The `@theme_selected_*` colors are now aliases
to the libadwaita accent colors variables. This commit
replaces all uses with the corresponding color,
except for the text colors.
`@theme_selected_bg_color` is not the appropriate color
to use for colored text. Instead, you should use
`@accent_color` which has been tested for proper contrast.
GcalEventPopover gives a preview of the event, and handy access
to the event description and information. It also allows easily
joining meetings if any one if available.
The list of supported meeting URLs is small now, but I hope
more people will contribute as we go.
It is also possible to edit the event through an edit button.
