[dev] Template or RENDERER for dynamic forms?

[Robin Rainton]

You know when you say you really should do one thing, but you just can't leave
the other alone? ;)

I was thinking that the several inputs I wanted on one line could be done as a
new type of variable, and that would suit quiet nicely. In the fosdem
presentation it says of types, "Not enough? Add your own ones." so away we
go...

One can add a new type into a form easily by doing this, which can be done in
your own code (I put in an include):

   class Horde_Form_Type_newvariabletype extends Horde_Form_Type {
     /* Some stuff for this type */
   }

Trouble is, the VarRenderer doesn't know how to draw this, and from what I can
see cannot be extended in a separate file. Given the fosdem slide think I've
missed something here because I could only make it work by doing adding 
this to
Horde/UI/VarRenderer/html.php:

   function _renderVarInput_newvariabletype(&$form, &$var, &$vars)
   {
     /* Some stuff to return the the inputs */
   }
   function _renderVarDisplay_newvariabletype(&$form, &$var, &$vars)
   {
     /* Some stuff to return displayed data */
   }

I'm not so great with this stuff, but seems to avoid the edit one would 
have to
extend the Horde_UI_VarRenderer and Horde_UI_VarRenderer_html classes 
with your
own extension and somehow get them (your own) referenced in 
Horde/Variables.php
(or would you have to extend that too?).

That seems awfully complicated, so guess I'm asking, what's the right 
way to do
that, "Not enough? Add your own ones." step?
