Details

The gtk:gesture-single class is a gtk:gesture implementation optimized for single-touch and mouse gestures. Under interaction, these gestures stick to the first interacting sequence, which is accessible through the gtk:gesture-single-current-sequence function while the gesture is being interacted with.

By default gestures react to both the button primary and touch events. The gtk:gesture-single-touch-only function can be used to change the touch behavior. Callers may also specify a different mouse button number to interact with through the gtk:gesture-single-button function, or react to any mouse button by setting 0. While the gesture is active, the button being currently pressed can be known through the gtk:gesture-single-current-button function.
