I'm looking to do a GUI with a similar look and feel of the Visual Studio .NET layout. What is the recommendation for mixing the tabbed mdi and the docking windows. Basically do you have to programatically handle the sizing of the tabbed MDI in the main window or is there a way to do this using something like the dock property = fill?
The DockingManager and TabbedMDI components work seamlessly with each other and there is no necessity for you to do anything beyond the normal creation/initialization required for the two components.
For instance, to add docking windows to the Essential Tools TabbedMDI sample, open up the sample's MainForm within the designer, add an instance of the Essential Tools DockingManager component, add the required dockable controls to the form, and set the EnableDocking extended property for the added controls. That's it! You're good to go now.
Setting the DockingManager's EnableContextMenu property to TRUE will show the default docking windows context menu, and similar to VS.NET, you can use the 'Dockable' menuitem to switch between docked/MDIChild modes.
For an advanced implementation of the VS.NET UI, please refer to the VSDemo sample that ships with Essential Tools.
