// Program Description:
// Interactive program to demonstrate TLayout window. It creates
// a frame window, colored child windows and a client window.
//
// The menu choice lets you bring up a dialog to let you set values for a
// TLayoutMetrics structure for the various child windows (the dialog is
// modeless, so you can layout several windows at the same time).
// A TLayoutMetrics (declared in layoutwi.h) has four TLayoutConstraints
// in it, X, Y, Width and Height. When the dialog comes up, you choose
// which constraint you want to select, then set the various members of
// that constraint.
// There are some constraints that you don't do with layout windows.
// For example, if you constrain the lmWidth edges of a X constraint, it
// will cause a error. (The lmWidth edge is best constrained through the
// Width constraint).
//
// Functionality Demonstrated:
// OWL: Low level use of TLayoutWindow and TLayoutMetrics
