I'll join the chorus in saying that IDL can probably do all you need it
to do and that I would think you would be crazy to write an IDL->VTK
.dlm. But then again, I know I have made my share of questionable
project design decisions because I couldn't resist a challenge :)

To Karl's point, (1) exists in the win32 api. The GetActiveWindow()
function will return (you guessed it) a handle to the active window. If
you write your IDL code such that you call this function in your .dlm
right after the window is realized then you're pretty safe. I use this
in my directInput .dlm.

Good luck. If you get something working you'll surely post the code,
right? ;)
