Questions tagged [qstyle]

QStyle is an abstract base class that is responsible for the look and feel of the GUI.

Qt has a set of classes subclassed from QStyle that represent native GUI styles for platforms that Qt supports.

Qt's widgets use QStyle to perform their drawing. Note that when subclassing, a developer should use QCommonStyle rather than QStyle as a base class.

The official documentation can be found here for Qt 4 and here for Qt 5.
