Description

GtkGestureLongPress is a GtkGesture implementation able to recognize long presses, triggering the “pressed” after the timeout is exceeded.

If the touchpoint is lifted before the timeout passes, or if it drifts too far of the initial press point, the “cancelled” signal will be emitted.

GtkGesture *
gtk_gesture_long_press_new (GtkWidget *widget);

Returns a newly created GtkGesture that recognizes long presses.

Parameters

widget

a GtkWidget

Returns

Signal Details

The “cancelled” signal

void
user_function (GtkGestureLongPress *gesture,
               gpointer             user_data)

This signal is emitted whenever a press moved too far, or was released before “pressed” happened.

user data set when the signal handler was connected.

Flags: Run Last

               gpointer             user_data)

This signal is emitted whenever a press goes unmoved/unreleased longer than what the GTK+ defaults tell.
