/*  [Description]

    This virtual Method is called when the window displayed in the
    SfxViewShell gets a StarView-Move() notification.

    This base implementation does not have to be called.     .

    [Note]

    This Method can be used to cancel a selection, in order to catch the
    mouse movement which is due to moving a window.

    For now the notification does not work In-Place.

(

)

/*  [Description]

    Override this Method to be able to react to the size-change of
    the View. Thus the View is defined as the Edit window and also the
    attached Tools are defined (for example the ruler).

    The Edit window must not be changed either in size or position.

    The Vis-Area of SfxObjectShell, its scale and position can be changed
    here. The main use is to change the size of the Vis-Area.

    If the Border is changed due to the new calculation then this has to be set
    by <SfxViewShell::SetBorderPixel(const SvBorder&)>. The Positioning of Tools
    is only allowed after the calling of 'SetBorderPixel'.

    [Example]

    void AppViewSh::OuterViewResizePixel( const Point &rOfs, const Size &rSz )
    {
        // Calculate Tool position and size externally, do not set!
        // (due to the following Border calculation)
        Point aHLinPos...; Size aHLinSz...;
        ...

        // Calculate and Set a Border of Tools which matches rSize.
        SvBorder aBorder...
        SetBorderPixel( aBorder ); // Allow Positioning from here on.

        // Arrange Tools
        pHLin->SetPosSizePixel( aHLinPos, aHLinSz );
