+// Implements a floating toolbar for the debugger.
+
+// Unfortunately, I couldn't get the KToolBar to work nicely when it
+// was floating, so I was forced to write these classes. I'm not sure whether
+// I didn't try hard enough or ... and I've forgotten what the problems were
+// now.
+
+// The problem with using this is that it will not dock as a normal toolbar.
+// I'm not convince that this is a real problem though.
+
+// So, if you can get it to work as a KToolBar, and it works well when the
+// app is running, then all these classes can be removed.
+
+// This code is very specific to the internal debugger in kdevelop.

+// I would have preferred to use normal decoration on the toolbar and removed
+// the iconify, close, etc buttons from the window title but again I kept running
+// into problems. Instead, I used no decoration and this class. Also this looks
+// similar to the KToolBar floating style.
