Details

The gtk:gesture-long-press object is a gtk:gesture 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.

Signal Details

The "cancelled" signal

lambda (gesture)    :run-last

gesture: The gtk:gesture-long-press object that received the signal.

The signal is emitted whenever a press moved too far, or was released before the "pressed" signal happened.

The "pressed" signal

lambda (gesture x y)    :run-last

gesture: The gtk:gesture-long-press object that received the signal.
x: The double float for the x coordinate where the press happened, relative to the widget allocation.
y: The double float for the y coordinate where the press happened, relative to the widget allocation.

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