    Virtual method of the SfxDockingWindow class. This method determines how

    implementation uses the floating mode, the size of the marked Floating
    Size. For horizontal alignment, the width will be the width of the outer
    DockingRectangle, with vertical alignment the height will be the height of
    the inner DockingRectangle (resulting from the order in which the SFX child
    windows are displayed). The other size is set to the current floating-size,
    this could changed by a to intervening derived class. The docking size must
    be the same for Left/Right and Top/Bottom.
