Description:
Sets given event handler of given display. The return code of the provided function should indicate whether this event was handled correctly. This implies telling the engine whether it is default code should be executed. See User Interface Event Handlers for the full list of handler names.
If applicable, see DIK KeyCodes for a list of key code constants, which are relevant to key related user interface events like onKeyDown and onKeyUp.
When using the event names listed here with the ctrlAddEventHandler, ctrlSetEventHandler, displayAddEventHandler or displaySetEventHandler commands, the prefix "on" in the event name must be removed (e.g. 'ButtonDown' instead of 'onButtonDown').
Groups:
