I am using Think Pascal. Plus I'm writing a MDEF. If I wanted to set
the PenPat to gray. How would I get access to the quickdraw global gray?
Thanks,
pat

This can be done as follows: var MyGray : array[1..2] of longint; .... MyGray[1]:=$55AA55AA; MyGray[2]:=$55AA55AA; ... To use this data in the program you must typecast it to type "pattern" e.g. like this: PenPat(pattern(MyGray)); By changing the data other patterns may be used as well, of cource. If you don't want to figure it out yourself, the HEX code for a specific pattern can be found in 'PAT '-resources. Use ResEdit and "Open general".

If you just want Grey, it's probably just as easy to create it on the fly with StuffHex. -- Uucp: ...{gatech,ames,rutgers}!ncar!asuvax!stjhmc!56.12!Chris.Gehlker Internet: Chris.Gehlker@p12.f56.n114.z1.fidonet.org
