Signals¶

Inherited:: Gtk.Gesture (5), GObject.Object (1)

Name	Short Description

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.
