public getSWFVersion() : Number

Returns an integer that indicates the Flash Player version for the movie clip was published. If the movie clip is a JPEG, GIF, or PNG file, or if an error occurs and Flash can't determine the SWF version of the movie clip, -1 is returned.

You can extend the methods and event handlers of the MovieClip class by creating a subclass.

Returns

Number - An integer that specifies the Flash Player version that was targeted when the SWF file loaded into the movie clip was published.

Example

The following example creates a new container and outputs the value of getSWFVersion(). It then uses MovieClipLoader to load an external SWF file that was published to Flash Player 7 and outputs the value of getSWFVersion() after the onLoadInit handler is triggered.

var container:MovieClip = this.createEmptyMovieClip("container", this.getUpperEmptyDepth());
var listener:Object = new Object();
listener.onLoadInit = function(target:MovieClip):Void {
    trace("target: " + target.getSWFVersion()); // target: 7
}
var mcLoader:MovieClipLoader = new MovieClipLoader();
mcLoader.addListener(listener);
trace("container: " + container.getSWFVersion()); // container: 8
mcLoader.loadClip("FlashPlayer7.swf", container);
