Ok, here's the problem:
A requester which will let the user set the size of a RAM buffer using a
prop gadget. What I NEED to do is to to update the amount display as the user
slides the gadget. (it looks like this)
Memory Buffer Requester
Size: ___ k

What I WANT to do is to update the ___ as the user moves the gadget. I know I
can do it using a window instead, then I can print the IText as I go, but I
already have the requester made up & worked into the code, and it SEEMS there
should be a way to do it.

Use the rastport that's part of the requesters' layer (something like req->ReqLayer->rp, check the include files.) Then you can just use PrintIText. -- You've heard of CATS?

You want to render directly into the Requester using PrintIText(), right? But you need a pointer to a RastPort, right? Well... -------- struct Requester *req; struct RastPort *rp; rp = req -> ReqLayer -> rp; /* Ta da! */ -------- I got this trick from John Draper (remember him?) _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ Leo L.
