Ah! It compiled. Thank you very much! And thanks to Michael for putting
together the sample project.
Now to get the CALayer to draw a path. Most of the documentation I've seen
suggest to do this with a delegate function, is that correct? Here is the
delegate function I've written (a.k.a. copied from another program):
//********************************************************************************
- (void)drawLayer:(CALayer *)theLayer
inContext:(CGContextRef)theContext {
CGMutablePathRef thePath = CGPathCreateMutable();
CGPathMoveToPoint(thePath,NULL,15.0f,15.f);
CGPathAddCurveToPoint(thePath,
NULL,
15.f,250.0f,
295.0f,250.0f,
295.0f,15.0f);
CGContextBeginPath(theContext);
CGContextAddPath(theContext, thePath );
CGContextSetLineWidth(theContext, 1);
CGContextSetRGBStrokeColor(theContext,0.0,0.0,1.0,1.0);
CGContextStrokePath(theContext);
}
//******************************************************
I'm just seeing the black background right now.
Again, thanks for your help and sorry I'm such a pain :)
