[wxhaskell-users] Custom controls

[Mads <mad...@ya...>]

Hi all

I am trying to create a custom control. Thus I have looked at this
example http://darcs.haskell.org/wxhaskell/samples/wx/CustomControl.hs .
But it does not really help me. I also tried the WxWidgets site and it
did not help much either.

What I would like is to take two textCtrl-s (or other controls) and
compose them into one bigger control. And still "inheriting" all the
functions/classes associated with `Window a`. And the new control should
also implement some classes which `Window a` do not, like Commanding.

I can compose two textCtrl-s, but not while "inheriting" Window. Thus I
have to implement all the classes Window implements. And even worse, I
can see no way of making my custom control work with functions like
`focusOn`, as they are defined in a class.

Anybody have such an example or some pointers?
