Every Top-Level window shows as an Icon (or Tab) in the Windows Taskbar.
A window that has no parent, or whose parent is the desktop window, is
called a top-level window in Windows.

In Xbase++, every dialog that has "AppDeskTop()" as both parent and owner
will be a top-level window. For more details on this and the concept of the
various dialog or window types, you might want to read Clayton Jones's
articles on that topic at: http://www.cjcom.net/articles/artmdi1.htm or
more generically for Windows in general, you can read more at:

Hope that helps,
