Thanks Matt. You were absolutely correct; the problems I have were in
-drawRect:. I'm still trying to track down a problem though, and I'm
not sure where it is. I've actually cut it down to some fairly simple
code. Here it is:
-(NSRect)rectForPage:(NSInteger)pageNumber
{
// Note the current page
currentPage = pageNumber-1;
float pHeight = linesPerPage * lineHeight;
NSRect returnRect = NSMakeRect(0.0, pHeight * currentPage,
pageRect.size.width, pHeight);
NSLog(@"x-origin: %f, y-origin, %f, height: %f, width: %f",
returnRect.origin.x,
returnRect.origin.y, returnRect.size.height,
returnRect.size.width);
return returnRect;
}
-(void)drawRect:(NSRect)rect
{
NSRect lineRect;
lineRect.origin.y = 0;
lineRect.origin.x = pageRect.origin.x;
lineRect.size.width = pageRect.size.width;
lineRect.size.height = lineHeight;
for (NSUInteger i=0; i<500; i++)
{
// Draw line number
lineRect.origin.y = (i * lineHeight);
NSString *lineString = [NSString stringWithFormat:@"%d",i];
[lineString drawInRect:lineRect withAttributes:attributes];
}
}
Now, this should simply print a line of integers down the left side of
the page. It does this for two pages - works perfectly - with lines 0
to 50 on the first page, and 51 to 100 on the second page, divided
correctly so there is no splitting of lines and so on. But the rest of
the pages are blank, and I can't figure out why. The NSLog from -
rectForPage: looks like this:
x-origin: 0.000000, y-origin, 0.000000, height: 606.899963, width:
576.000000
x-origin: 0.000000, y-origin, 606.899963, height: 606.899963, width:
576.000000
x-origin: 0.000000, y-origin, 1213.799927, height: 606.899963, width:
576.000000
x-origin: 0.000000, y-origin, 1820.699951, height: 606.899963, width:
576.000000
x-origin: 0.000000, y-origin, 2427.599854, height: 606.899963, width:
576.000000
x-origin: 0.000000, y-origin, 3034.499756, height: 606.899963, width:
576.000000
x-origin: 0.000000, y-origin, 3641.399902, height: 606.899963, width:
576.000000
x-origin: 0.000000, y-origin, 4248.299805, height: 606.899963, width:
576.000000
x-origin: 0.000000, y-origin, 4855.199707, height: 606.899963, width:
576.000000
x-origin: 0.000000, y-origin, 5462.099609, height: 606.899963, width:
576.000000
... so it looks to me as if all the pages are being properly selected.
Oh, and if I change the paper size and orientation, similar things
happen (but not entirely consistently). So, if I choose landscape, it
only prints two pages. But if I choose envelope #10, it prints three
pages. Thanks,
Darcy
Several lines down? Could that be the extra 500 you keep introducing?
Really, since what you need to say in rectForPage depends completely
on how
you draw in drawRect, which you don't show, it's hard to guess from
here
what rectForPage *should* be (or whether you even need to implement
it)...
