Drag just passes incoming drag-events to the displayed popup menu.

popup_gesture ->event: event

Allow the popup to change it's menu_items before it is shown.

popup_gesture ->terminate: event

The terminate method performs the following:

• Set the popup_gesture<-context and -current variables to @nil
• event->post to the -current popup menu
• popup->execute the menu, providing the context @see popup->execute

popup_gesture ->verify: event

Verify tries to find the popup-menu to be displayed and sets the -context attribute of the popup_gesture to the event-receiver if it is not set to @nil.

If the popup_gesture<->popup attribute of the gesture is set, this popup menu is used. If it is a function object, the function is evaluated. See popup_gesture<-popup.

Otherwise, the event<-master is requested a popup with popup_gesture<-popup.

After finding a popup object, this object is sent popup->update to update its menu_items. If, after graphical<-active or‘popup popup_gesture<-members’is empty, popup_gesture->verify fails.
