|
|
|
|
An `AdwPreferencesGroup` represents a group or tightly related preferences,
|
|
which in turn are represented by [class@PreferencesRow].
|
|
|
|
To summarize the role of the preferences it gathers, a group can have both a
|
|
title and a description. The title will be used by [class@PreferencesWindow]
|
|
to let the user look for a preference.
|
|
|
|
## AdwPreferencesGroup as GtkBuildable
|
|
|
|
The `AdwPreferencesGroup` implementation of the [iface@Gtk.Buildable] interface
|
|
supports adding [class@PreferencesRow]s to the list by omitting "type". If "type"
|
|
is omitted and the widget isn't a [class@PreferencesRow] the child is added to
|
|
a box below the list.
|
|
|
|
When the "type" attribute of a child is `header-suffix`, the child
|
|
is set as the suffix on the end of the title and description.
|
|
|
|
## CSS nodes
|
|
|
|
`AdwPreferencesGroup` has a single CSS node with name `preferencesgroup`.
|
|
|
|
## Accessibility
|
|
|
|
`AdwPreferencesGroup` uses the `GTK_ACCESSIBLE_ROLE_GROUP` role.
