Difference between ThreeDBorderWindow and SingleBorderWindow

Question

In WPF XAML, WindowStyle can be None, SingleBorderWindow, ThreeDBorderWindow, ToolWindow.

I tried the options myself and also looked into MSDN, yet I cannot tell any difference visually between ThreeDBorderWindow and SingleBorderWindow. The "ThreeDBorder" looks just as 2-D as SingelBorder. What are their difference?

Answer 1

You have to switch to Windows Classic theme to see the difference. If you are using a "modern" theme like Windows 7 there is no difference.

Below you have the SingleBorderWindow to the left and ThreeDBorderWindow to the right when using Windows Classic theme on my computer. (The innermost gray border is from a control in the window and is not part of the window border.)

The "3D" border has an inside highlight that I guess gives it a raised or three dimensional look.
