I'm trying to write a very simple little application that has a custom
view in it that displays some PostScript. I've threaded the thing
together with the IB, and the drawSelf method for the view is getting
executed, but nothing happens in the window. Here's some of the code
for the CustomView:
-drawWindow:sender
{
[self display];
return (self);
}
-drawSelf:(NXRect *)r:(int)count
{
putchar ('\007');
fflush (stdout);
PSsetgray (11.0 / 12.0);
PSrectfill (bounds.origin.x, bounds.origin.y,
bounds.size.width, bounds.size.height);
...
return (self);
}
I hookup up a menu item to the drawWindow method, and every time I
push the button, I hear the beep (putchar ('\007')) but nothing
changes in the window. Am I missing something somewhere?

shouldnt you do a [myView lockFocus] before you start drawing? (and a [myView unlockFocus] after you're finished) a PSflushgraphics might also help.. -- ----------------------------------------------------------------------------- absinthe@milton.u.washington.edu | "Don't get Odd, get Even"

Did you #import <dpsclient/wraps.h> ? Without that you don't get any errors, but things are painted that small in your view that you can't see them. At least that was what happened once to me...
