Objects of class wxLayoutConstraint can be associated with a window to define
the way it is laid out, with respect to its siblings or the parent.
and two for the window size. By setting some or all of these constraints appropriately,
the user can achieve quite complex layout by defining relationships between windows.

+In wxWidgets, each window can be constrained relative to either its {\it
siblings} on the same window, or the {\it parent}. The layout algorithm
therefore operates in a top-down manner, finding the correct layout for
the children of a window, then the layout for the grandchildren, and so
on. Note that this differs markedly from native Motif layout, where
constraints can ripple upwards and can eventually change the frame

always `boss' and specifies the size of the outer window, to which
subwindows must conform. Obviously, this might be a limitation in some
circumstances, but it suffices for most situations, and the
