I need to create Hyperlink to the companies web site, but the link

field. I am sure it is something with NSMutableAttributedString but
can't seem to figure it out. I though maybe there was some Cocoa
class to do that, but could not find anything. Does anyone have one
or know where I might be able to find one?
Thanks in advance.
I've done it by creating an attributed string using
initWithHTML:documentAttributes: and bound it to the NSTextField.
The field should be both selectable and allows rich text. The one
drawback is no hand cursor when the mouse hovers over it.
You can get the pointing hand cursor by subclassing the window's
content view (the window holding the text field, that is) and override
-resetCursorRects like this:
#import "AboutBoxContentView.h"
@implementation AboutBoxContentView
- (id)initWithFrame:(NSRect)frame
{
self = [super initWithFrame:frame]; if (self) {/*Initialization code
here.*/} return self;
}
- (void)drawRect:(NSRect)rect {/* Drawing code here.*/}
// The only thing to override here, the following ensures that I get
the pointing hand cursor on the mailto link.
- (void)resetCursorRects
{
NSCursor *pointy = [NSCursor pointingHandCursor];
[self addCursorRect:NSMakeRect(180.0, 31.0, 36.0, 17.0)
cursor:pointy];// rect of mailto link, hardcode is alright
[pointy setOnMouseEntered:YES];
}
@end
NSDictionary *attrsDictionary = [[NSDictionary alloc]
initWithObjectsAndKeys: [NSFont labelFontOfSize:[NSFont
labelFontSize]], NSFontAttributeName, nil];
NSMutableAttributedString *htmlLinkString =
[[NSMutableAttributedString alloc] initWithHTML:[[NSString
stringWithFormat:@"<a href=\"[EMAIL PROTECTED]">%@</a>", self.sourceProjectURL,
self.sourceProjectURL] dataUsingEncoding: NSUTF8StringEncoding]
documentAttributes: nil];
[htmlLinkString addAttributes:attrsDictionary range:NSMakeRange(0,
[htmlLinkString length])];
