Re: How to remove/hide the default-scrolling-arrows from a list

[Jennifer Fell]

Thanks a lot to everyone who replied and helped. I'm getting the following 
error message while trying to use the code as you advised (FYI, I made sure 
to define the ALLOW_ACCESS_TO_INTERNALS_OF_LISTS):

Error: illegal use of incomplete struct/union/class 'struct ListAttrTag'
test.cpp line 211       ListAttrType listAttr;
Thanks,
Jenni

You'll need to define
#define ALLOW_ACCESS_TO_INTERNALS_OF_LISTS
Then you can do this
           ListAttrType    listAttr;
           int        attrSize = sizeof(listAttr);
           err = MemMove (&listAttr, &(listP->attr), attrSize);
           listAttr.hasScrollBar = 1;
           err = MemMove ( &(listP->attr), &listAttr, attrSize);
I doubt this will be portable when writing pure cobalt apps but it does 
the trick for os 5 and below.  It's a lot of work to implement a table 
when all you want is a listbox with a real scrollbar.
