Struct gtk4::ShortcutsGroup [−][src]
pub struct ShortcutsGroup(_);Expand description
A ShortcutsGroup represents a group of related keyboard shortcuts
or gestures.
The group has a title. It may optionally be associated with a view of the application, which can be used to show only relevant shortcuts depending on the application context.
This widget is only meant to be used with ShortcutsWindow.

Implementations
Creates a new builder-pattern struct instance to construct ShortcutsGroup objects.
This method returns an instance of ShortcutsGroupBuilder which can be used to create ShortcutsGroup objects.
The size group for the accelerator portion of shortcuts in this group.
This is used internally by GTK, and must not be modified by applications.
A rough measure for the number of lines in this group.
This is used internally by GTK, and is not useful for applications.
The size group for the textual portion of shortcuts in this group.
This is used internally by GTK, and must not be modified by applications.
An optional view that the shortcuts in this group are relevant for.
The group will be hidden if the property::ShortcutsWindow::view-name
property does not match the view of this group.
Set this to None to make the group always visible.

Tries to cast to an object of type T. This handles upcasting, downcasting
and casting between interface and interface implementors. All checks are performed at
runtime, while downcast and upcast will do many checks at compile-time already. Read more
