39.0. "Compound string structure?" by TOWNS::SIMMONS () Thu Jan 26 1989 19:41


I have an application in which it would be nice to access the text field of 
a compound string directly.  Essentially, I would like to do something along
the lines of the following:

       ...

       static char *text;
       static DwtCompString current_drink;

       ...

       current_drink = DwtLatin1String("Apple Juice");

       ...

       text = current_drink.text;

Is this sort of thing possible?  Assuming that a compound string is stored in 
a structure of some sort, could someone please post what this structure looks 
like?


	Thanks,

    a) This kind of question is more suited for 
    harbor::decwindows_programming. 
                                   
    b) You've seen DwtGetNextSegment?
    
    c) Maybe you are trying to modify the contents of a compound string,
    e.g. changing "Apple Juice" into "Orange Juice", but without creating a
    new string? This seems not to be allowed...

    Looking inside a compound string is explicitly forebidden.  The
    internal structures may very well change in the future, especially
    because of attempts at standardization going on.  For now,
    the only guarantee for upward compatibility is to stick with the
    routines supplied.

	re .0: See the Toolkit Routines Reference Manual, chapter 5.

	re .to_whom_it_may_concern: This question is asked at least
	once a week, which suggests that it needs to be better documented.
	Maybe an example should be put in the Guide to Application
	Programming? At least put an example in the compound string
	chapter of the Toolkit Routines Reference Manual.

    In HARBOR::DECWINDOWS_PROGRAMMING note 59 I have asked what compound
    string access routines are requested.
