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 TextField
object's listener list), the method returns a value of false.
Example
The following example creates an input text field called my_txt. When the user types into the
field, information about the number of characters in the text field is displayed in the Output
panel. When the user types into the field, information about the number of characters in the
text field writes to the log file. If the user clicks the removeListener_btn instance, then the
listener is removed and information is no longer displayed. If the user clicks the
removeListener_btn instance, then the listener is removed and information no longer writes
to the log file.
this.createTextField("my_txt", this.getNextHighestDepth(), 10, 10, 160,
20);
my_txt.border = true;
my_txt.type = "input";
var txtListener:Object = new Object();
txtListener.onChanged = function(textfield_txt:TextField) {
trace(textfield_txt+" changed. Current length is:
"+textfield_txt.length);
};
my_txt.addListener(txtListener);
removeListener_btn.onRelease = function() {
trace("Removing listener...");
if (!my_txt.removeListener(txtListener)) {
trace("Error! Unable to remove listener");
}
};

removeTextField (TextField.removeTextField
method)
public removeTextField() : Void
Removes the text field. This operation can only be performed on a text field that was created
with MovieClip.createTextField(). When you call this method, the text field is removed.
This method is similar to MovieClip.removeMovieClip().
