CCheckListBox

Hi all,

Has anyone used this new (VC4) class?  It appears to be incomplete
(i.e. the MeasureItem() member function is not implemented).

Thanks,
Andy

Hi all,

Just to answer my own (dumb?!?) question.  A checked list box must
have the OWNERDRAWFIXED and HASSTRINGS styles.  This is not documented
as far as I can see, but I think may be something to do with these
clever new controls which can draw themselves (message refelction?).
Anyone know anymore about this?

Thanks,
Andy (hoping his post wasn't too far below "intermediate" level :-)

Yes, I have used it without any problem. However, I have not tried 
out everything yet, esspecially the MeasureItem().

I sent an answer to your question on 1/13/96 at 21:03 pacific time.  Did you 
not receive it?

It's not documented because it's not a requirement.  If your listbox has 
OWNERDRAWFIXED and HASSTRINGS, you can use the base class implementation of 
CCheckListBox.  If your list box doesn't have these styles, then you need to 
handle some of  the messages the list box will generate.

You should be able to find this information in the source.  It _is_ a 
documentation bug that the overview doesn't explain the relationship of your 
list box object to the CCheckListBox or CCheckListBox-derived  object, and 
that's been fixed for VC++ 4.1.

CCheckListBoxes don't have much to do with message reflection.
