EventControllerFocusRef
public struct EventControllerFocusRef : EventControllerFocusProtocol, GWeakCapturing
GtkEventControllerFocus
is an event controller to keep track of
keyboard focus.
The event controller offers [signalGtk.EventControllerFocus::enter
]
and [signalGtk.EventControllerFocus::leave
] signals, as well as
[propertyGtk.EventControllerFocus:is-focus
] and
[propertyGtk.EventControllerFocus:contains-focus
] properties
which are updated to reflect focus changes inside the widget hierarchy
that is rooted at the controllers widget.
The EventControllerFocusRef
type acts as a lightweight Swift reference to an underlying GtkEventControllerFocus
instance.
It exposes methods that can operate on this data type through EventControllerFocusProtocol
conformance.
Use EventControllerFocusRef
only as an unowned
reference to an existing GtkEventControllerFocus
instance.

property instead.Declaration
