pub struct GestureRotate { /* private fields */ }
Expand description

GestureRotate is a Gesture implementation able to recognize 2-finger rotations, whenever the angle between both handled sequences changes, the signal::GestureRotate::angle-changed signal is emitted.

Implements

GestureExt, EventControllerExt, glib::ObjectExt

Implementations

Returns a newly created Gesture that recognizes 2-touch rotation gestures.

widget

a Widget

Returns

a newly created GestureRotate

Creates a new builder-pattern struct instance to construct GestureRotate objects.

This method returns an instance of GestureRotateBuilder which can be used to create GestureRotate objects.

If self is active, this function returns the angle difference in radians since the gesture was first recognized. If self is not active, 0 is returned.

Returns

the angle delta in radians

This signal is emitted when the angle between both tracked points changes.

angle

Current angle in radians

angle_delta

Difference with the starting angle, in radians
