This option should contain a function name to be executed each time TinyMCE intercepts and handles a event such as keydown, mousedown and so forth. The format of this function is: handleEvent(event), where inst is the editor instance object reference. If the handle event function returns false it will terminate the internal event handling.
Example of usage of the handle_event_callback option:
// Remember to enable the possibility to switch status messages in the browser before trying the example below function myHandleEvent(e) { window.status = "event:" + e.type; return true; // Continue handling } tinyMCE.init({ ... handle_event_callback : "myHandleEvent" });
