Detailed Description

The QCommonStyle class encapsulates the common Look and Feel of a GUI.

\inmodule QtWidgets

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. \omit , although the extra functions that QCommonStyle provides, e.g. drawComplexControl(), drawControl(), drawPrimitive(), hitTestComplexControl(), subControlRect(), sizeFromContents(), and subElementRect() are documented here. \endomit
