Missing API for what I need to do? [message #14163] |

I have a TabCtrl populated with five tabs using
TabCtrl::Item& Add(Ctrl& slave, const char *text)
We need a special behavior for the control that happens to
be index 4. I sense the tab Action with a callback. I don't
know which tab is selected except by index. So, my magic
number 4 is supposed to be related to the special object that requires additional handling. The problem is that I have
no way to verify that in the callback. There seems to be no
way to get at the slave control and make a comparison to
the control of interest for special handling.
If the order of the tab pages change (other programmers, etc.),
callback will be doing the wrong thing. There seems to be no
way to determine that the current selected item is the one of interest.
Somehow, I expected to have an API that I could get at the
slave object, test it, and perhaps apply special handling if
it is the object of interest.
Is there some way of doing this with the API already in place?

I have tried your changes, but they are not working.
The problem is, that in your code you return ctrl instead of slave, but ctrl member seems to be used only by some dead code in TabCtrl.
Could you change it to slave? Or add a new GetSlave() method returning slave?
Maybe it would be useful to remove ctrl member also.

What about this topic? Here is the patch:
