Abstract

An operating system provides a number of window elements that the operating system itself or applications may use in displaying a window. The operating system includes a dialog box for enabling a user to adjust the individual sizes of the respective window elements independently of the size of the window. The bitmaps for the window elements are stored in a cache that is re-drawn each time the user changes the size of any of the window elements.
