Hi again,
It turned out that a QDcokarea was not nice: Calling 
toolbar->setMovingEnabled( false ) in the constructor still had no effect. 
and suddenly the main toolbar(s) could be docked into the file selector.

I figured out that something - probably qmainwindow::polish() sets all toolbar 
children of a main window to a global property when the window is initially 
shown. So, I came up with this class, which fixes the issue:

/*
    This is a hack to allow to have the toolbar without a resize
    handle.
    As it seems QMainWindow(?) recursively sets all toolbars
    movable according to the global setting in it's polish() method,
    this class is there mainly to reset that, and to handle resizing.
    It is required to setTB() before the widget is shown, that is in
    the parent constructor, or add the toolbar in the constructor,
    but there is no access to it (which could easily be changed;)
*/
#include <qframe.h>
#include <ktoolbar.h>
class TBContainer : public QFrame {
  Q_OBJECT
  public:
    TBContainer( QWidget *parent=0, KToolBar *toolbar=0 )
      : QFrame( parent, "toolbar container hack" ), tb( toolbar ){};
    void setTb( KToolBar *toolbar) { tb = toolbar; };
  public slots:
    void polish() {
      if (tb) {
        setMinimumHeight( tb->sizeHint().height() );
        tb->setMovingEnabled( false );
      }
    };
  protected:
    void resizeEvent( QResizeEvent *e ) {
      if( tb ) {
        tb->resize( e->size() );
      }
    }
  private:
    KToolBar *tb;
};

Carsten: thanks for responding, and I did look in kfiledialog.cpp, as that is 
the only window i could think of using a ktoolbar outside the main windows. I 
also use you nice silenceQToolbar trick;)
