[lazarus] Control type csCListBox?

[Andrew Johnson]

CListBox is a problem for the gtk2 interface as well. just so you know.
I cannot figure out how to properly implement it, and the backward
compatibility doesn't actually support multiple columns properly in
gtk2, so it kinda defeats the purpose of even having a separate one.

There is an issue here with the fact that clist(a very gtk1.2 specific
widget) is intended to also allow widgets within the columns, like
checks buttons images etc, but gtk2 doesn't support this the same way,
it only allows custom drawing etc. So I think more needs to be thought
about where it is currently used and what it is used for and determine
what is possible to implement in all backends consistently. Even if it
means breaking current code.
