Parameters

None.

Nothing.

Description

Event handler; invoked when a movie clip has input focus and a key is pressed. The onKeyDown event is invoked with no parameters. You can use the Key.getAscii and Key.getCode methods to determine which key was pressed. You must define a function that executes when the event is invoked.

The movie clip must have input focus enabled and set in order for the onKeyDown event to work. First, the focusEnabled property must be set to true for the movie clip. Then, the clip must be given focus. This can be done either by using the Selection.setFocus method or by setting the tab key to navigate to the clip.

If the Selection.setFocus method is used, the path for the movie clip must be passed to the Selection.setFocus method. It is very easy for other elements to take the focus back once the mouse is moved.

Example

The following example defines a function for the onKeyDown method that sends a trace action to the Output window:

myMovieClip.onKeyDown = function () {
	trace ("onKeyDown called");
};

The following example sets input focus:

MovieClip.focusEnabled = true;
Selection.setFocus(MovieClip);
