Description
- 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's 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: KeyDown & KeyUp.

- Always use displayAddEventHandler instead, as DSetEH overwrites other (peoples') DEH.
