Glad to hear the UnitCompEditor worked well for you. I stil want to know 
how you wrapped the interface. :)

The reason it took about 10 minutes is because it calls the OTA method 
to create a method. This is what happens when you double-click an event 
on the object inspector and it creates the event code and places your 
cursor there. But, in order to write to the editor using the OTA, it 
requires you to write the ENTIRE file (if I remember right... it's been 
awhile). There isn't a "read from position". So with each method OnEval 
it parses the whole file, finds where to put the code and writes out the 
whole code. Then it repeats for each method. So you can see how it gets 
slower and slower. :) The idea is that it would be good for wrapping a 
form, datamod, utilities, etc. Wrapping a whole thing like the VCL, OTA, 
Indy, etc. would be a pain. It's best suited to things that are likely 
to change where you want easier access to it for updating it, etc.

I'm just days away from a new wrapper interface. An application that 
takes it fully through the process of reading a .pas file and creating 
the wrapper in a configurable way. Your customizations are stored and 
persist. It creates a component to do all the wrapping so it isn't in 
the DFM.

Please share your wrapping solution... I'm very curious. :)
