I am using LSC for the first time, so this may be a stupid question. I am trying to get a color window. However, LSC doesn't recognize that type. I looked at the sample code TubeTest on AppleLink and they got a color window using GetCWindow into a regular WindowPtr. Should i do the same? If so, how can i access the CWindowPtr specific fields like the pixel map and background color? I tried typecasting, but it diddn't seem to like that. --Michael O'Rourke

However, LSC doesn't recognize that type. >I looked at the sample code TubeTest on AppleLink and they got a color window read the example program I posted not more than 3 days ago in this very newsgroup. It takes the datafile that was included in the recent ray-tracing binary, and draws it correctly and much faster than the drawer in the ray-tracing posting. It gives examples of dealing with color windows, color tables, palettes, and pixmaps. all in Lightspeed C. --- David Phillip Oster --"Unix Version 7 was an improvement not Arpa: oster@dewey.soe.berkeley.edu --only over its predeccessors, but also its Uucp: {uwvax,decvax}!ucbvax!oster%dewey.soe.berkeley.edu --successors."

LSC should be able to handle casting them when you want to. Get an upgrade, if you are using an older version than 3.0.

Figuring out what could be wrong based on what people post is a lot like debugging code without a debugger. Very challenging. Here's my guess about Michael's problem: I think he's relying on <MacHeaders> rather than including all the .h files and since color.h isn't in MacHeaders, LSC doesn't recognize color windows. But my solution does assume LSC 3.0, so I could be wrong. /alastair/
