The WidgetInvoker will decide if a long press has been made or not. We watch out for TOUCH_END events and when a long-press event has been seen before we stop further propagation of the event, hence there won't be any button-release or clicked events available to the user of the widget. There are several widgets using the WidgetInvoker, and those handle differently touch events. The GtkButton does have a widget implementation to handle touch events, it does stop further propagation and emits the pressed/released signal for further consumption [1]. We will not get a button-press/button-release event for a touch event in this case. The default behaviour for widgets e.g. a TreeView is to transform the touch events into pointer events [2], for those widgets we do get a button-press/button-release event for a touch events.
