◆ updateState()

void QX11PaintEngine::updateState ( const QPaintEngineState &  state)
overridevirtual

Reimplement this function to update the state of a paint engine.

When implemented, this function is responsible for checking the paint engine's current state and update the properties that are changed. Use the QPaintEngineState::state() function to find out which properties that must be updated, then use the corresponding \l {GetFunction}{get function} to retrieve the current values for the given properties.
