I am currently trying to make a basic control gui for an on-board system. Ene of the things I'd like to be displayed is a visual of the costmap from the navigation stack. Since this can be viewed in Rviz, I am assuming there is a method for displaying this information through qt as well.

I'm currently using qt version 4.8 with pyqt, and am assuming that the needed widget would be a Graphics View widget. However, there is little documentation I can find on doing such a task. Any assistance would be appreciated.
