Hello All!
I seem unable to align text when drawing using drawAt:point. The NSTextView
shows it OK (so the attributes appear correct), but drawing of the text doesn't
show alignment...
My code is:
- (void) awakeFromNib {
NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
[nc addObserver:self selector:@selector(updateText:)
name:NSTextViewDidChangeTypingAttributesNotification object:nil];
[nc addObserver:self selector:@selector(updateText:)
name:NSTextDidChangeNotification object:nil];
NSString *str = @"This is a test\nAnd this text should be right
aligned\nBut for some reason, in the image, isn't";
NSMutableParagraphStyle *pStyle = [[NSMutableParagraphStyle new]
autorelease];
[pStyle setAlignment:NSRightTextAlignment];
NSDictionary *attrs = [NSDictionary
dictionaryWithObjectsAndKeys:pStyle, NSParagraphStyleAttributeName, nil];
NSAttributedString *as = [[[NSAttributedString alloc]
initWithString:str attributes:attrs] autorelease];
[[text textStorage] setAttributedString:as];
}
- (void) updateText:(NSNotification*)aNotification {
[self textChanged:self];
}
- (IBAction) textChanged:(id)sender {
NSAttributedString *string = [text attributedString];
NSSize bounds = [string size];
if(bounds.width > 0 && bounds.height > 0) {
NSImage *image = [[[NSImage alloc] initWithSize:bounds]
autorelease];
[image lockFocus];
@try {
[string drawAtPoint:NSZeroPoint];
} @finally {
[image unlockFocus];
}
[view setImage:image];
} else {
[view setImage:nil];
}
}
A sample of what I see when I run this is here:

I must be missing something really obvious. Any ideas?
