CL_EventChain_ButtonPress3

Overview

Event chains are used to route an event to an event listener. The toplevel event chain for button presses, located in CL_Input, is called by ClanLib, but you can also send false events by calling on_button_press() yourself. Note that CL_EventChain_ButtonPress is inheriated from CL_EventButtonPress, so you can add a chain to the toplevel chain. This is useful, if you want to do more advanced routing of events.
