ModernDockArt is a custom wxDockArt class, that implements a look similar to Firefox and other recents applications.
Is uses wxRenderer and XP themes whenever possible, so it should look good even if the user has a custom theme.
A future improvement might be to add a DrawSmallCloseButton() function to wxRenderer (in wxWidgets) so that you we don't have to make custom code for each platform. Other controls, like tabbed interfaces and the like would also benefit from this.
You will need the wxDockArt improvements from my previous posting for it to compile.
You are free to use this in any way you like.
