Reloading CTabItems in a CTabFolder [message #981648] Mon, 12 November 2012 15:27 Go to next message

I have a multipage editor. In one of the pages I display one or more
views of some data. The Views are drawn on one or more CTabItems that
are in a CTabFolder. This all works fine. However, during runtime,
the user can change the parameters of the views (and even add or remove
views). So I need to be able to wipe out the current CTabFolder
(and/or its CTabItems) and re-create it.

My question is what is the best approach for this? It's not obvious
how exactly to remove the CTabFolder from the ScrolledForm. I'd prefer
to just remove each of the CTabItems from the folder but it isn't
obvious to me how to do that either. If someone can suggest the right
way or point me to some example code, I would be appreciative.

TIA, Ric

Well, I experimented with simply calling dispose() on each of the
CTabItems in the CTabFolder, then recreating the CTabItems. This seems
to work fine, but am still not sure this is kosher behaviour.

That's the only possibility. Note that the children composites are not
disposed when you dispose the CTabItem!

Thanks Tom. And thanks for pointing out the additional cleanup
required, I'll make sure to take care of those as well.
