MACROMEDIA FLASH 8-ACTIONSCRIPT 2.0 LANGUAGE - Page 1168

1168 ActionScript classes
A reference to the text field instance is passed as a parameter to the onScroller and
onChanged handlers by the event source. You can capture this data by putting a parameter in
the event handler method. For example, the following code uses
txt as the parameter that is
passed to the
onScroller event handler. The parameter is then used in a trace statement to
send the instance name of the text field to the Output panel.
my_txt.onScroller = function(textfield_txt:TextField) {
trace(textfield_txt._name+" scrolled");
};
Availability: ActionScript 1.0; Flash Player 6
Parameters
listener:Object - An object with an onChanged or onScroller event handler.
Returns
Boolean -
Example
The following example defines an
onChanged handler for the input text field my_txt. It then
defines a new listener object,
txtListener, and defines an onChanged handler for that
object. This handler will be invoked when the text field
my_txt is changed. The final line of
code calls
TextField.addListener to register the listener object txtListener with the text
field
my_txt so that it will be notified when my_txt changes.
this.createTextField("my_txt", this.getNextHighestDepth(), 10, 10, 100,
22);
my_txt.border = true;
my_txt.type = "input";
my_txt.onChanged = function(textfield_txt:TextField) {
trace(textfield_txt._name+" changed");
};
var txtListener:Object = new Object();
txtListener.onChanged = function(textfield_txt:TextField) {
trace(textfield_txt._name+" changed and notified myListener");
};
my_txt.addListener(txtListener);
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.
