Class Details¶

class Gtk.GestureRotate(**kwargs)¶

Bases:	`Gtk.Gesture`
Abstract:	No
Structure:	`Gtk.GestureRotateClass`

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

classmethod new(widget)[source]¶

Parameters:	widget (`Gtk.Widget`) – a `Gtk.Widget`
Returns:	a newly created `Gtk.GestureRotate`
Return type:	`Gtk.Gesture`

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

New in version 3.14.

get_angle_delta()[source]¶

Returns:	the angle delta in radians
Return type:	`float`

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.

New in version 3.14.

Signal Details¶

Gtk.GestureRotate.signals.angle_changed(gesture_rotate, angle, angle_delta)¶

Signal Name:	`angle-changed`
Flags:	`RUN_FIRST`
Parameters:	gesture_rotate (`Gtk.GestureRotate`) – The object which received the signal angle (`float`) – Current angle in radians angle_delta (`float`) – Difference with the starting angle, in radians

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

New in version 3.14.
