Collaboration diagram for DisplayController:

[legend]List of all members.

Detailed Description

A singleton class that is the interface between GUI and the displays.

It frequently implements the application logic which should neither be in the GUI nor in the display objects.

Todo:: DisplayController shouldn't need to know about the DataRepFactory.

Should probably move methods that use it to DataRepController.

Todo:: Shouldn't const_cast<BinToColor *> the return value from getValueRep() of the plotter object in the setValueBrkPt member function.

A member function returning a non const pointer to a BinToColor object should be implemented in the PlotterBase class and that should be used in the setValueBrkPt member function.
