EventControllerMotionProtocol
public protocol EventControllerMotionProtocol : EventControllerProtocol
GtkEventControllerMotion
is an event controller meant for situations
where you need to track the position of the pointer.
This object was added in 3.24.
The EventControllerMotionProtocol
protocol exposes the methods and properties of an underlying GtkEventControllerMotion
instance.
The default implementation of these can be found in the protocol extension below.
For a concrete class that implements these methods and properties, see EventControllerMotion
.
Alternatively, use EventControllerMotionRef
as a lighweight, unowned
reference if you already have an instance you just want to use.
