RenderUnit
Rendering size units.
A paint effect which draws an offset and optionally blurred drop shadow.
A paint effect which draws an offset and optionally blurred drop shadow within a picture.
Struct for storing maximum and minimum scales for measurements in map units.
Base class for visual effects which can be applied to QPicture drawings.
virtual void readProperties(const QVariantMap &props)=0
