The optional attributes that follow are divided into two groups. Window layering affects how windowed objects are arranged on the screen; i.e., where they appear and whether they appear above or below other windowed objects. In general, this layering behavior is only determined for windowed objects having the same parent, i.e., windows having the same parent can be custom layered, and their parents will be layered among its siblings.</P>
