// your statements here

}

Parameters

Description

Event handler; invoked when a text field loses keyboard focus. The onKillFocus method receives

one parameter,

no object receives the focus,

newFocus contains the value null.

Example

The following example creates two text fields called first_txt and second_txt. When you give

focus to a text field, information about the text field with current focus and the text field that lost

focus is displayed in the Output panel.

this.createTextField("first_txt", 1, 10, 10, 300, 20);

first_txt.border = true;

first_txt.type = "input";

this.createTextField("second_txt", 2, 10, 40, 300, 20);

second_txt.border = true;

second_txt.type = "input";

first_txt.onKillFocus = function(newFocus:Object) {

trace(this._name+" lost focus. New focus changed to: "+newFocus._name);

};

first_txt.onSetFocus = function(oldFocus:Object) {

trace(this._name+" gained focus. Old focus changed from: "+oldFocus._name);

}
