Hi Kevin,

may be but then something is completely weird: if I call 'HasScrollbar' 
I get for the horizontal and vertical scrollbar a 'true' back. But the 
scrollbars are not shown.

If I add in the previous example the last line, then, there should be 
definitely two scrollbars. But there aren't any.


    wxScrolledWindow* Ptr1(new 
wxScrolledWindow(this,wxID_ANY,wxDefaultPosition,wxSize(50,50),wxScrolled
WindowStyle | wxALWAYS_SHOW_SB));
    Ptr1->Hide();

    wxScrolledWindow* Ptr2(new 
wxScrolledWindow(this,wxID_ANY,wxDefaultPosition,wxSize(100,100),wxScroll
edWindowStyle | wxALWAYS_SHOW_SB));
    
    
    Ptr2->SetSize(200,200);
    Ptr2->SetVirtualSize(400,400);
