removeListener (Selection.removeListener method)

Removes an object previously registered with Selection.addListener().

Availability: ActionScript 1.0; Flash Player 6

Parameters

listener:Object - The object that will no longer receive focus notifications.

Returns

Boolean - If listener was successfully removed, the method returns a true value. If listener was not successfully removed--for example, if listener was not on the Selection object's listener list--the method returns a value of false.

Example

The following ActionScript dynamically creates several text field instances. When you select a text field, information displays in the Output panel. When you click the remove_btn instance, the listener is removed and information no longer displays in the Output panel.

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";
    }
}

var selectionListener:Object = new Object();
selectionListener.onSetFocus = function(oldFocus, newFocus) {
    trace("Focus shifted from "+oldFocus+" to "+newFocus);
};
Selection.addListener(selectionListener);

remove_btn.onRelease = function() {
    trace("removeListener invoked");
    Selection.removeListener(selectionListener);
};
