Loading UI controls in the same applet instance
Recent Java and browser versions do not work very well when more than one applets are loaded on the page (e.g. IE crashes when reloading such pages, in some browsers Java objects cannot be passed between two applets). Hence we modified the DiagramApplet, used to host the client-side DiagramView control, to also show the miscellaneous UI controls such as Overview, ShapeListBox and Ruler. This approach also allowed us to expose these controls in Silverlight mode. The Java and Silverlight UI controls can be shown and customized using the following properties of the server DiagramView control:

~ bool ShowRuler: show or hide the Ruler
~ ShowShapeListBox ShowShapeListBox: can be set to None/Left/Right
~ ShapeList ShapeListFilter: a list of shapes that should be shown by the ShapeListBox
~ Size ShapeListIconSize: specifies the size of ShapeListBox icons
~ Color ShapeListFillColor: specifies the color of ShapeListBox icons
~ bool ShowOverview: show or hide the Overview
~ string OverviewTitle: title of the Overview window
~ bool OverviewFitAll: enables or disables FitAll mode for the Overview control

The server-side ShapeListBox and Overview controls are still necessary in ImageMap and Canvas mode.
