first of all thanks for all the archives, i've been reading them a lot.
question:
in a view subclass i obtain my bounds:
NSRect bounds = [self bounds];
size is: 480 x 276
pass it to an object that draws:
[sfp drawWaveformFrom:0.0 to: [sfp duration] inRect: bounds];
SFP:
-(void)drawWaveformFrom: (float)start to:(float)end inRect:(NSRect)rect
{
NSLog(@"rect: %f %f",rect.size.width, rect.size.height);
..
}
and when it gets there its garbage
x: 3.5 y: -3.68934881e+19 size: 0 x 0
sorry if this is obvious, but web and archive searching hasn't solved
it for me.
Looks like you're examining the values before you've executed the first
line in the function.
What happens when you do this:
-(void)drawWaveformFrom: (float)start to:(float)end inRect:(NSRect)rect
{
NSLog(@"start: %f" end:%f", start, end);
NSLog(@"rect: %f %f",rect.size.width, rect.size.height);
NSLog(@"about to leave the method.."); // break here.
..
}
