MACROMEDIA FLASH 8-ACTIONSCRIPT 2.0 LANGUAGE - Removelistener (Selection.removelistener Method)

1076 ActionScript classes
Example
The following example demonstrates how to determine when input focus changes in a SWF
file between several dynamically created text fields. Enter the following ActionScript into a
FLA or AS file and then test the document:
this.createTextField("one_txt", 1, 0, 0, 100, 22);
this.createTextField("two_txt", 2, 0, 25, 100, 22);
this.createTextField("three_txt", 3, 0, 50, 100, 22);
this.createTextField("four_txt", 4, 0, 75, 100, 22);
for (var i in this) {
if (this[i] instanceof TextField) {
this[i].border = true;
this[i].type = "input";
}
}
this.createTextField("status_txt", this.getNextHighestDepth(), 200, 10,
300, 100);
status_txt.html = true;
status_txt.multiline = true;
var someListener:Object = new Object();
someListener.onSetFocus = function(oldFocus, newFocus) {
status_txt.htmlText = "<b>setFocus triggered</b>";
status_txt.htmlText += "<textformat tabStops='[20,80]'>";
status_txt.htmlText += "&nbsp;\toldFocus:\t"+oldFocus;
status_txt.htmlText += "&nbsp;\tnewFocus:\t"+newFocus;
status_txt.htmlText += "&nbsp;\tgetFocus:\t"+Selection.getFocus();
status_txt.htmlText += "</textformat>";
};
Selection.addListener(someListener);
The MovieClip.getNextHighestDepth() method used in this example requires Flash Player
7 or later. If your SWF file includes a version 2 component, use the version 2 components
DepthManager class instead of the
MovieClip.getNextHighestDepth() method.
