Detailed Description

Viewing and editing component of a MDFDocument.

Part of the wxWidgets document/view framework. View of a Machine Object Model consists of EditParts defining the editing behaviour of the model components. For each EditPart in the view exists a figure defining the visualization of the component. The EditParts form a tree hierarchy starting from the top level contents EditPart, which is a child of the RootEditPart. This class also keeps track of the selected EditParts.
