Remarks

This method calculates:

1. The rectangle of the screen where the drop down should be shown

2. The rectangle (in screen coordinates) of the owner element. Owner element is the element that shows the drop-down and is connected to it - like a menu item that shows its sub menus or a combobox element that shows its drop-down.

After calculating the screen and the element rectangles this method calls the basic method.
