You can pass a reference to the calling class to Alert class and call a method in the calling class.. here's an example:
public class CallingClass { public CallingClass() { panel.Add(new AlertClass(this)); } public void yesButtonAction() { // Do yes button action here } } public class AlertClass { private CallingClass callingClass; public AlertClass(CallingClass reference) { this.callingClass = reference; ...... Yes = new Button("Yes",new ClickListener(){ public void onClick(Widget sender) { callingClass.yesButtonAction(); result="yes"; } }); } } This might work.
