RotateAction

Required Methods§

Source

fn connect_rotate<F: Fn(&Self, &Actor, f64) -> bool + 'static>( &self, f: F, ) -> SignalHandlerId

The ::rotate signal is emitted when a rotate gesture is recognized on the attached actor and when the gesture is cancelled (in this case with an angle value of 0).

§actor

the Actor attached to the action

§angle

the difference of angle of rotation between the initial rotation and the current rotation

§Returns

true if the rotation should continue, and false if the rotation should be cancelled.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
