 // COMPAT: Vertical orientation and undocking were broken by the Qt4 port
 //         so kpMainWindow::init() keeps this tool bar in a constant position for
 //         the time being.  To help make this workaround possible, we use QDockWidget,
 //         instead of KToolBar, to prevent XMLGUI from managing the tool
 //         bar position.  This also allows us to use QMainWindow::setCorner().
 //
 //         A nice must-have side-effect is that we are now resizeable, which
 //         is good for configurable (and potentially large) color collections.
 //         So we should probably keep it as a QDockWidget in the long-term
 //         and once we fix orientation and undocking, we should put XMLGUI
 //         support back in, somehow (create a "KDockWidget" class?).
