MovieClip 903
onEnterFrame (MovieClip.onEnterFrame handler)
onEnterFrame = function() {}
Invoked repeatedly at the frame rate of the SWF file. The function that you assign to the
onEnterFrame event handler is processed before any other ActionScript code that is attached
to the affected frames.
You must define a function that executes when the event handler is invoked. You can define
the function on the timeline or in a class file that extends the MovieClip class or that is linked
to a symbol in the library.

Example
The following example defines a function for the
onEnterFrame event handler that sends a
trace() action to the Output panel:
my_mc.onEnterFrame = function () {
trace ("onEnterFrame called");
}
onKeyDown (MovieClip.onKeyDown handler)
onKeyDown = function() {}
Invoked when a movie clip has input focus and user presses a key. The onKeyDown event
handler is invoked with no parameters. You can use the
Key.getAscii() and
Key.getCode() methods to determine which key the user pressed. You must define a
function that executes when the event handler is invoked. You can define the function on the
timeline or in a class file that extends the MovieClip class or is linked to a symbol in the
library.
The
onKeyDown event handler works only if the movie clip has input focus enabled and set.
First, the
MovieClip.focusEnabled property must be set to true for the movie clip. Then,
the clip must be given focus. You can do this by using
Selection.setFocus() or by setting
the Tab key to navigate to the movie clip.
If you use
Selection.setFocus(), you must pass the path for the movie clip to
Selection.setFocus(). It is very easy for other elements to take the focus back after a user
moves the mouse.
