QDockingWindow is the control to use for an advanced UserInterface experience. It is similar to the way Microsoft presents the toolwindows in Visual Studio .Net., but we have added some special features.

You can dock toolwindows on eachother, on bars at the side of the MainForm or on every other dockable position on the MainForm. You can set it in a tabbed appearance and let the windows slide in and out. That is all the Visual Studio .Net toolwindows do. Next to that you can fully customize their colors, borders, gradients, fonts and so forth.
