About time! Imagine two text fields name src_txt and dest_txt. When the user (or ActionScript) places something into src_txt and then moves focus to something else, the text in dest_txt is automatically updated.
// Placed DataBindingClasses in the Library import mx.data.binding.*; var src = new EndPoint(); src.component = src_txt; src.property = "text"; src.event = "focusOut"; var dest = new EndPoint(); dest.component = dest_txt; dest.property = "text" new Binding(src, dest);
