Detailed Description

The TransferBox widget class.

This class renders the transfer function. Every Point from m_points has a corresponding color that gets rendered when a paintEvent occurs. Points are managed, displayed and returned by the HoverPoints class. The widget is drawn with a QLinearGradient. Users can select the colors from a QColorDialog.
