3287.0. "Getting Started Developing DW Appications" by CARTUN::CLIFFORD () Thu Aug 30 1990 19:05

    Can anyone sugguest an approach to develop DECWINDOWS 
    applications on the VAX?  Are there courses, manuals, books, on 
    the subject that anyone can recommend?
    
    I'm a BASIC, COBOL, and VAX C programmer.  Is this sufficient?
    Should I know MACRO?
    
    Thanks

3287.1QUARK::LIONELFree advice is worth every centThu Aug 30 1990 21:3411
    I suggest you start with the manuals that VMS supplies, notably
    the VMS Guide to Developing DECwindows Applications (or something
    like that).  It introduces the concepts you need and gives examples.
    
    VAX C is probably the best of the languages you name for applications,
    as most of the examples are in C.  COBOL is nearly impossible, as
    there are (I don't think) any declarations provided.  BASIC would
    be ok, but there is no BASIC-oriented documentation or examples.
    Ignore MACRO.

And also take a look at every other book avaialble.  Our doc is 
comprehensive, but sometimes pretty unclear on alternatives, etc.  
Douglas Young's is particularly good on toolkit.  There is also a 
couple of classes and an SPI course offered by us.  It is very big and 
requires much more than just picking up a programming language.  Get 
all the help you can.

3287.3MS/DOS Windows and VAXCARTUN::CLIFFORDFri Aug 31 1990 18:2910
    The books I see in the book store are for developing applications 
    written in MS/DOS.  Do the concepts carry over but the syntax is different?
    
    
      Like  CD\NEW_DIRECTORY vs SET DEF [.NEW_DIRECTORY]?  
    
    I saw a book called "Understanding Windows" using MS/DOS.  Is that
    comparable to what it takes to do it on the VAX?

3287.4Windows is not XGILROY::kleeKen LeeFri Aug 31 1990 18:378
Re: .3
Books about "Windows" are really about Microsoft Windows for MS-DOS
PCs.  This has little do do with the X Window System for VMS and UNIX
workstations.  A regularly updated bibliography (in PostScript) of
books and articles on the X Window System may be found in
gilroy:/wsl/doc/misc/Xbibliography.PS.

    I think it will be much easier to understand the XToolkit if you have the
    XLib concept.

Re: .5

I disagree.  It is possible to create complete applications without needing
to understand or use Xlib at all.  Xlib is the lower level that should be
learned only if necessary.

3287.7Another X-rated responseSRFSUP::HERKELRATHIf they fire one, we'll fire one. One fired, sirFri Sep 14 1990 13:436
    re: .5
    I agree with .5. Where you can develop complete applications using
    toolkits, your "comfortablity" would be much higher if you understood
    XLIB. I suggest you do both. Start using the toolkit while you are
    reading up on XLIB. That way when you need to make X calls you can
    (and you will need to make X calls at some point).
3287.8New books from Digital PressPEACHS::BELDINSat Sep 15 1990 15:5918
	May I suggest a new book by Digital Press that is good 
	intro and reference to the toolkit from a 'generic' (Intrinsics)
	point of view?  "X Window System Toolkit" by Paul Asente and
	Ralph Swick just came out and it provides the explanations
	behind the 'mystery' that the 'gray' books just don't address.
	The order number is EY-E757E-DP.  The book addresses widget
	writing as well as application writing and appears to be
	thoughtfully written.   Although it does not address the
	specifics of the Digital toolkit, it is easy to address that
	once you've gotten through the basics.  A companion book
	is the "X Window System", order number EY-755E-DP.

	This is what the DEC docs should have been in the first 
	place...
