Class TextDelegate

  • public class TextDelegate
extends Object
    To replace static text in an animation at runtime, create an instance of this class and call setText(String, String) to replace the hard coded animation text (input) with the text of your choosing (output).

    Alternatively, extend this class and override getText(String) and if the text hasn't already been set by setText(String, String) then it will call getText(String).
