For a little bit of information look at:

Without going into depth I have tested this under Linux/GTK with 
dlangui:

     WindowState state;
     Rect    rect;
     rect.left   = 800;
     rect.top    = 10;
     rect.bottom = 600;
     rect.right  = 1000;
     bool bRet= window.setWindowState(state,
                                      false,
                                      rect);

     window.show();

This changed the position and size of my initial window.
