MovieClip

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.
Availability:
ActionScript 1.0; Flash Lite 2.0
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 a key is pressed. The
onKeyDown
event handler
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 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. This can be done either by using
Selection.setFocus()
or by
setting the Tab key to navigate to the clip.
If
Selection.setFocus()
is used, the path for the movie clip must be passed to
Selection.setFocus()
. It is very easy for other elements to take the focus back after the
mouse is moved.
