Events are a basic and important message passing system for WoW and its UI. The [[Event API]] and the WoW UI are built around these messages being recieved by [[XML/Frame|Frames]] from WoW, through the use of event handlers, and by expressly registering for messages for a frame. An OnLoad event fires for a Frame during load, allowing it register for these event messages. The [[Events_A-Z_(Full_List)|List of all Events]] details this event API by providing a reference for each of these messages. | |||

== Summary == | |||
From a UI perspective, [[Events]] in WoW are messages sent by the WoW client to the UI Frames (via frame script handlers), mostly in reaction to things occurring in the game world. | |||
The World of Warcraft interface is entirely event driven: all interface code is invoked in response to an event (or OnUpdate "events"). All script execution must be completed before a frame is rendered; therefore, event processing code that takes too long or contains an infinite loop will freeze the client. | |||
You can register your Frame-derived widget to receive an event using the '''frame:[[API_Frame_RegisterEvent|RegisterEvent]]("eventName")''' function. When the events occur, they will be delivered to the OnEvent script handler, which can be set using '''frame:[[API_Frame_SetScript|SetScript]]("OnEvent", handlerFunc)'''. To unregister an event, use '''frame:[[API_Frame_UnregisterEvent|UnregisterEvent]]("eventName")'''. | |||
