onKillFocus = function(newFocus:Object) {}
Invoked when a button loses keyboard focus. The onKillFocus handler receives one parameter, newFocus, which is an object representing the new object receiving the focus. If no object receives the focus, newFocus contains the value null.
Availability: ActionScript 1.0; Flash Player 6
newFocus:Object - The object that is receiving the focus.
The following example demonstrates how statements can be executed when a button loses focus. Create a button instance on the Stage called my_btn and add the following ActionScript to Frame 1 of the Timeline:
this.createTextField("output_txt", this.getNextHighestDepth(), 0, 0, 300, 200);
output_txt.wordWrap = true;
output_txt.multiline = true;
output_txt.border = true;
my_btn.onKillFocus = function() {
output_txt.text = "onKillFocus: "+this._name+newline+output_txt.text;
};
Test the SWF file in a browser window, and try using the Tab key to move through the elements in the window. When the button instance loses focus, text is sent to the output_txt text field.
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.
