Re: How to blink with a focus ring of the text box?
Another way is to make the cursor stop at the end of the limit, and if the user keeps banging on the keyboard, show an alert message stating the character limit on the field.

Not because it's a terrible idea, but because introducing yet another subtle[-ish] sound/flash/color behavior whose meaning isn't obvious into the UI is a terrible idea. Apart from the problem of foisting yet another arbitrary UI convention on the user, the use of color alone to indicate status is not a great idea, and the use of red to signal an error is culturally specific and so possible off-putting in some parts of the world (though the boat may have already sailed on that last issue). I think the 'NSImageNameInvalidDataFreestandingTemplate' solution, associated with label text that explains why the icon is there, is an excellent way to show the error, without introducing any new UI behaviors. > I am wondering if there's a way to do this, notifying the user that he can't > enter any more text into NSTextField edit box? I think you're making a mistake in assuming it's a good idea to prevent the user from entering the excess text. In many scenarios, it's probably better to go ahead and let the user enter any amount of text, and complain afterwards. You can show an error condition as described above, or (if, say, your window doesn't have room for the entire error description), you can put up an alert sheet (when enter is pressed) that says what's wrong and what the limits are. OTOH, if this is something where the user is very aware of the length limitation (for example, the 4-digit passcode used to unlock an iPhone), I'd be inclined to just reject the excess text and beep (perhaps with a temporary error status message if there's room for it in the UI, perhaps changing the color of something in the UI, though not necessarily the text field).

NSImageNameInvalidDataFreestandingTemplate, with red applied to it. Has the advantage of not relying entirely on color to distinguish it; changing the blue focus ring to another color may not be something all users can detect. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Or if on Lion, a popover attached to the text field with an explanation of the error. Or a small label underneath showing a count of remaining characters, that turns red once the length goes over. The last one is something that I've actually used. I like it because it allows the user to enter what he's thinking without interruption, then edit it until it fits. "Banging into the end" and not being able to enter more, going back and deleting a few characters, then going to the end and typing a few more, and repeating until you figure out an abbreviated form that fits is much more tedious. -- Scott Ribe scott_r...@elevated-dev.com http://www.elevated-dev.com/ (303) 722-0567 voice ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I don't know about the red overlay, but I agree that it's a very intriguing extension to the UI. As suggested, you could use a custom formatter to reject strings over a certain length. That will do the expected thing and play the bonk! sound effect when the user tries to enter too much text. But you should definitely file a radar asking for that flash behavior. That sounds like a promising line of investigation. Plus we could really stand to get access to the focus ring. --Kyle Sluder___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: How to blink with a focus ring of the text box?
Adding to my own post I just found this in my snippets collection:
This listing shows how you draw such a focus ring. It requires you to override
the NSCell drawWithFrame:inView: In this method, if the cell is supposed to
draw evidence of first-responder status, set the rectangle for the focus ring,
call NSSetFocusRingStyle with an argument of NSFocusRingOnly, and then create
and fill a bezier path defining that rectangle. Filling in this case simply
draws the ring.
- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView;
{
// other stuff might happen here
if ([self showsFirstResponder]) {
// showsFirstResponder is set for us by the NSControl that is drawing
us.
NSRect focusRingFrame = cellFrame;
focusRingFrame.size.height -= 2.0f;
[NSGraphicsContextsaveGraphicsState];
NSSetFocusRingStyle(NSFocusRingOnly);
[[NSBezierPath bezierPathWithRect: NSInsetRect(focusRingFrame, 4.0f,
4.0f)] fill];
[NSGraphicsContext restoreGraphicsState];
}
// other stuff might happen here
}
So possibly you could create your own NSTextFieldCell, set your NSTextField to
use it, call [super drawWithFrame.] somewhere in the above method to do the
standard drawing and move on from there. The flashing could be implemented
using a CALayer animation or something.
If you manage to implement this you should make it open source :-) since I
guess it's quite a bit of work to get it done.

Re: How to blink with a focus ring of the text box?
I'm guessing you're wanting this for invalid characters as well as exceeded number of characters? It sounds like an intriguing extension to the UI.

Re: How to blink with a focus ring of the text box?
Read carefully:
The original poster stated: "any more text" - or are you suggesting that he
should disable the text box when a certain number of characters are reached? I
guess not.
AFAIK, the focus ring is not accessible programmatically, except form setting
it by making something the first responder.
You could use a text formatter or one of the validation methods and simply stop
accepting key strokes, change the text color to red and/or display an alert.

The correct way to notify a user that he can't enter text in a text box is to
disabled it.
