Hi Wade,
I can't see a [labelFont set] in your code so that labelView kows what
font to use for it's size calculations. (I'm guessing that it is
calculating the size based upon a non-bold font variant and you are
then setting the font to bold (larger) just before you draw...)
Cheers,
aid

The following code, from an NSView subclass:

float fontSize = [NSFont labelFontSize];
NSFont *labelFont = [NSFont boldSystemFontOfSize:fontSize],
*textFont = [NSFont labelFontOfSize:fontSize];
static NSSize minSize = {0, 0};
NSText *labelView = nil, *textView = nil;
labelView = [[[NSText alloc] initWithFrame:NSMakeRect(0,
currentPosition, 150, space)] autorelease];
[labelView setFont:labelFont];
[labelView setString:label];
[labelView setMinSize:minSize];
[labelView setHorizontallyResizable:YES];
[labelView setVerticallyResizable:NO];
[labelView sizeToFit];
[labelView setEditable:NO];
[labelView setUsesFontPanel:NO];
[labelView setDrawsBackground:NO];
[self addSubview:labelView];
...
}
The problem is that for some text sizeToFit reduces the size too much,
so that the last character is forced onto the next line. One simple
example is the string @"Email". One workaround I've found is to set
the minimum width to 10 + ceil([labelFont widthOfString:label]), but
apart from the fact that the 10 is an arbitrary and meaningless
constant (probably dependent on the font and/or size), widthOfString
is depreciated. The NSString additions that replace it aren't
suitable for this use.
I don't know why I have to add 10 to the width. Anything less doesn't
fix it, anything equal to or above does. Strangely, adding 10 (and no
more) doesn't change the spacing for the working strings from without
it. So it's a "perfect" workaround in my little sandbox usage.
The problem still remains, nonetheless, that sizeToFit doesn't.
Anyone have any idea why, or at least a "proper" way to make it work?
I've only seen the problem with the bold system font as yet -
presumably that's a key.
