Trait components::RotateActionExt [−][src]
pub trait RotateActionExt: 'static {
pub fn connect_rotate<F>(&self, f: F) -> SignalHandlerId
where
F: 'static + Fn(&Self, &Actor, f64) -> bool;
}Required methods
pub fn connect_rotate<F>(&self, f: F) -> SignalHandlerId where
F: 'static + Fn(&Self, &Actor, f64) -> bool, [src]
F: 'static + Fn(&Self, &Actor, f64) -> bool,
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.
