gtk:gesture-single-button (object)

object -- a gtk:gesture-single object
button -- an unsigned integer for the button number to listen to, or 0 for any button

The accessor for the button slot gets or sets the button number the single gesture listens to. If 0 the single gesture listen for any button. If non-0, every button press from a different button number will be ignored. Touch events implicitly match with button 1.
