## Detailed Description

This abstract class implements some of the widget's look and feel that is common to all GUI styles provided and shipped as part of Qt.

Since QCommonStyle inherits QStyle, all of its functions are fully documented in the QStyle documentation.

See also QStyle and QProxyStyle.
