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.
