QPaintEngineState Class Reference
^{[QtGui module]}

The QPaintEngineState class also provide the painter() function which returns a pointer to the painter that is currently updating the paint engine.

An instance of this class, representing the current state of the active paint engine, is passed as argument to the QPaintEngine::updateState() function. The only situation in which you will have to use this class directly is when implementing your own paint engine.

See also QPaintEngine.
