Owner-drawn components

[ballpointpenthief]

Hello.
I think the subject line is accurate. Anyway...

How would I go about extending a component so that it can pick up
messages?

I want the user to be able to put objects onto the screen, and move
them around.

I was hoping I could:
- extend Component
- Set a boundary for where it 'exists'
- Add a component listener

.... However it doesn't seem to be that simple...

Any suggestions?

Thanks,
Matt
