Class Details¶

class Gtk.GestureSwipe(**kwargs)¶

Bases:: Gtk.GestureSingle
Abstract:: No
Structure:: Gtk.GestureSwipeClass

GtkGestureSwipe is a GtkGesture for swipe gestures.

After a press/move/…/move/release sequence happens, the [signal`Gtk`.GestureSwipe::swipe] signal will be emitted, providing the velocity and directionality of the sequence at the time it was lifted.

If the velocity is desired in intermediate points, [method`Gtk`.GestureSwipe.get_velocity] can be called in a [signal`Gtk`.Gesture::update] handler.

All velocities are reported in pixels/sec units.

classmethod new()[source]¶

Returns:: a newly created GtkGestureSwipe
Return type:: Gtk.Gesture

Returns a newly created GtkGesture that recognizes swipes.

get_velocity()[source]¶

Returns:

whether velocity could be calculated

velocity_x:: return value for the velocity in the X axis, in pixels/sec
velocity_y:: return value for the velocity in the Y axis, in pixels/sec

Return type:

(bool, velocity_x: float, velocity_y: float)

Gets the current velocity.

If the gesture is recognized, this function returns True and fills in velocity_x and velocity_y with the recorded velocity, as per the last events processed.

Signal Details¶

Gtk.GestureSwipe.signals.swipe(gesture_swipe, velocity_x, velocity_y)¶

Signal Name:

swipe

Flags:

RUN_LAST

Parameters:

gesture_swipe (Gtk.GestureSwipe) – The object which received the signal
velocity_x (float) – velocity in the X axis, in pixels/sec
velocity_y (float) – velocity in the Y axis, in pixels/sec

Emitted when the recognized gesture is finished.

Velocity and direction are a product of previously recorded events.
