#import 

@interface FontController : NSObject {
    IBOutlet NSTextField *text;
}
- (IBAction)takeFontFamilyFrom: (id)sender;
- (IBAction)takeFontSizeFrom: (id)sender;
- (IBAction)takeFontAttributeFrom: (id)sender;
@end

#import "FontController.h"

NSFontManager *fm;

@implementation FontController
+ (void)initialize
{
    fm = [NSFontManager sharedFontManager];
}
- (IBAction)takeFontFamilyFrom: (id)sender
{
    NSFont *font = [text font];
    font = [fm convertFont: font
                  toFamily: [sender stringValue]];
    [text setFont: font];
}
- (IBAction)takeFontSizeFrom: (id)sender
{
    NSFont *font = [text font];
    font = [fm convertFont: font
                    toSize: [sender doubleValue]];
    [text setFont: font];
}

- (IBAction)takeFontAttributeFrom: (id)sender
{
    NSFont *font = [text font];
    NSFontTraitMask attribute = [sender tag];
    if (NSOnState == [sender state])
    {
        font = [fm convertFont: font toHaveTrait: attribute];
    }
    else
    {
        font = [fm convertFont: font toNotHaveTrait: attribute];
    }
    [sender setState: ([fm traitsOfFont: font] & attribute)];
    [text setFont: font];
}
@end
