// This file is built from former NTMain.pxx duplicated in many executables
// extending DRAW Test Harness.
// Now is implemented only in one instance.

// Differences between CAS.CADE versions:
//  - in C21 Draw_Appli is defined in Draw.cxx (DRAW UL) and calls externally
// defined Draw_InitAppli. Moreover, on WNT Draw_Appli was not declared as 
// Standard_EXPORT and therefore it has to be duplicated explicitly in this
// code as in Draw.cxx.
//  - in C30 Draw_Appli accepts Draw_InitAppli as parameter which is given to
// it in each executable. Draw_Appli is declared as Standard_EXPORT and
// therefore it needs not to be duplicated.
  
// To have only one instance of this file and to call it from all the executables
// thereare defined macros in .hxx that replace main/WinMain functions and which
// calls _main_/_WinMain_ defined in this file with specified Draw_InitAppli.
// To avoid Unresolved symbols on WNT, Draw_InitAppli is explicitly defined in this
// file as simple invoker of the function statically stored in this file and which
// is initialized by main/_WinMain_.  

// WARNING: Although versions C21 and C30 are synchronised as much as they can,
// there are two versions of this file for both configurations. This is explained by:
// - Standard_IMPOR is differently defined,
// - Draw_Appli is differently declared.

//  MAIN a la sauce WNT
//  EXPLICATION : un MAIN sous NT, c est quelque chose ... different de sous UNIX
//  ilya un tas de trucs a initialiser
//  Deux aspects : le main et Draw_Appli
//  le main est specifique : arguments, creation de "console"
//  Draw_Appli aussi, mais comme certains peuvent le redefinir, et que
//  NT ne permet pas cela, eh be il est duplique dans chaque main ...
//  Ceci a l identique. Youpi
//
//  Ce source comprend :
//  - un main repris : WinMain, qui en particlier definit une "console"
//  - un Draw_Appli repris
//  - la plupart des ifdef WNT sont laisses pour memoire
//  MAIS CE CODE N EST COMPILABLE QU EN NT
//
//  MODE D EMPLOI
//  Dans le source de l exec .cxx, Inclure ce gros paquet (NTMain.pxx)
//  a la place des includes courants et du main, en ifdef WNT of course
//
//  On laisse les includes specifiques ainsi que le Draw_InitAppli
//    qui lui aussi est specifique
//  
//  ATTENTION, avant de faire umake, taper cette commande magique (?)
//  setenv (WOK_EXETYPE) W
