How to access the handle of the Frame window ?

Question

How to access the handle of the frame window through out the application ?. I want to display an alert box, while I click the fifth inner child component of the Frame . I am using Dialog Class for the alert box, I have to pass the frame handle to the Dialog constructer, I am getting the handle of the frame by getParent().getParent()......getParent().. But can any one suggest any better solution.

If you application extends Frame or JFrame, you could simply refer to "this", or if you create a global or final Frame object that you use as your "top-level" component, you could refer to it this way. Additionally, if you're ever in a situation where you really need to go all the way to the top through n levels of components, I believe you could always do something like this...
// assume myContainer is the "child" component that you're on, and you want to find its top-level parent
Container c = myContainer;
while (c.getParent() != null) {
     c = c.getParent();
}
