TDecoratedFrame has only one constructor,

TDecoratedFrame(TWindow* parent,
  const char far* title,
  TWindow* clientWnd,
  bool trackMenuSelection = false,
  TModule* module = 0);

Parameter	Explanation
parent The window's parent window object. Use zero if the window you're creating is the main window (which does not have a parent window object). Otherwise use a pointer to the parent window object. This is the only parameter that you must provide.
title	The window title, which appears in the caption bar of the window. If you do not specify anything, no title is displayed in the title bar. clientWnd Lets you specify a pointer to a client window for the frame window. If you do not specify anything, by default the constructor gets a zero, meaning that there is no client window.
trackMenuSelection	Lets you specify whether menu commands should be tracked. When tracking is on, the window tries to pass a string to the window's status bar. The string passed has the same resource name as the currently selected menu choice. You should not turn on menu selection tracking unless you have a status bar in your window. If you do not specify anything, by default the constructor gets false, meaning that it should not track menu commands.
module	Passed to the base class constructor as the TModule parameter for that constructor. This parameter defaults to 0.
