DESCRIPTION

The QWSDecoration class allows the appearance of the Qt/Embedded Window Manager to be customized.

Qt/Embedded provides window management to top level windows. The appearance of the borders and buttons (the decoration) around the managed windows can be customized by creating your own class derived from QWSDecoration and overriding a few methods.

This class is non-portable. It is available only in Qt/Embedded.

See also QApplication::qwsSetDecoration() and Qt/Embedded.
