No. This is only the initial dimensions. To do auto resizing you can trap
the resize event for the parent and then call setRect() for those controls
you need to reposition. eg...

procedure Resize_MainWin(integer self, integer event, sequence parms)
  setRect(fld1, 0.2, 0.2, 0.6, 25, 1)
  setRect(fld2, {w32AltEdge,-40}, 5, 40, 0.25, 1)
end procedure
setHandler(MainWin, w32HResize, routine_id("Resize_MainWin"))
