Rebuild our view of the document. Happens whenever we change some field/aspect of an underlying UML object used to create the view. If connections are right, then the UMLObject will send out the modified() signal which will trigger a call to re-generate the appropriate code within the code document. Our burden is to appropriately prepare the tool: we clear out ALL the textblocks in the KTextEdit widget and then re-show them after the dialog disappears.
