Well, if I were to set about doing this, I'd try the following:

0. Get the parent window of the dialog box.

    Window parent = this.getParent();

1. Get the location of the parent window.

    Point parentLoc = parent.getLocation();

2. Get the width and height of the parent window.

    int parentWidth = parent.getWidth();

    int parentHeight = parent. getHeight();

3. Do the math:

    int thisX = parentLoc.x + (parentWidth - this.getWidth())/2;
   
    int thisY = parentLoc.y + (parentHeight - this.getHeight())/2;


That should do it.
