onKillFocus = function(newFocus:Object) {}
Invoked when a text field loses keyboard focus. The onKillFocus method 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.
newFocus:Object - The object that is receiving the focus.
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);
}
