That works! Thank you so much for your help.
I have another question regarding focus ring animation for a text field. This
is a document based application. In the document window there are many text
fields. After opening a document window - the first time a text field is
clicked there is no focus ring animation. Thereafter when any text field is
clicked in the window the focus ring will animate.
Do you have any insight as to why the animation does not occur the first time a
text field is clicked?

Yes Safari’s Address and Search field has the behavior that I am looking for.
First click selects the entire text field and you also get an animated focus
ring.
Exactly how to achieve that on OS X 10.10 (with or without a focus ring) is
another matter. I have parred back my custom NSTextField subclass to just what
is shown below. A custom NSNumberFormatter is used but I removed it. The only
other thing going on is the text field is programmatically placed in the super
view.
Your initial suggestion.
@implementation MyTextField
- (instancetype)initWithFrame:(NSRect)frame
{
self = [super initWithFrame:frame];
if (self) {
[self.cell setFocusRingType:NSFocusRingTypeNone];
}
return self;
}
- (void)awakeFromNib
{
[self.cell setFocusRingType:NSFocusRingTypeNone];
}
- (BOOL)becomeFirstResponder
{
BOOL result = [super becomeFirstResponder];
if(result) {
[self performSelector:@selector(selectText:) withObject:self
afterDelay:0];
}
return result;
}
@end
RESULTS: Text is selected but rapidly changes to no selection. No focus ring as
expected. Intermittent error Bad cursor rect event, flags = 256.
You say that Safari apparently does this.
@implementation MyTextField
- (void)mouseDown:(NSEvent *)event
{
NSText *editor = self.currentEditor;
assert(editor && "Current editor is nil!");
assert(editor.isFieldEditor && "Editor not a field editor!");
NSRange range = NSMakeRange(0, editor.string.length);
[editor setSelectedRange:range];
[super mouseDown:event];
}
@end
RESULTS: Text not selected. Focus ring normal. No error message.
Another version of what Safari may do.
@implementation MyTextField
- (void)mouseDown:(NSEvent *)event
{
[self selectText:self];
[super mouseDown:event];
}
@end
RESULTS: Text is selected but rapidly changes to no selection. Focus ring is
intermittent. No error message.
So in summary Safari’s Address and Search field has the behavior that I am
looking for. First click selects the entire text field and you also get an
animated focus ring. However on OS X 10.10 Yosemite nothing works for me except
performSelector:withObject:afterDelay: using a non-zero delay value.

Yes I have access to the field editor for the NSTextField. Directly setting the
selection using the field editor however does not work.
- (BOOL)becomeFirstResponder
{
BOOL result = [super becomeFirstResponder];
if(result) {
NSText *editor = self.currentEditor;
assert(editor && "Current editor is nil!");
assert(editor.isFieldEditor && "Editor not a field editor!");
NSRange range = NSMakeRange(0, editor.string.length);
[editor setSelectedRange:range];
}
return result;
}
The above code does not work.
There is some sort of interaction between NSTextField (and or the field editor)
and the runloop that has changed for the worse in OS X 10.10 Yosemite. The only
code that works is to override becomeFirstResponder and then schedule the
selectText: message with the runloop to execute after a non zero delay. I have
not been able to get anything else to work.
A comment by Daniel Wabyick at the end of this stackoverflow question suggests
that this was a problem in OS X 10.9 Mavericks but have been unable to
duplicate that.
http://stackoverflow.com/questions/2195704/selecttext-of-nstextfield-on-focus
So in summary in OS X 10.10 selecting all the text of an NSTextField when the
user clicks it has become difficult.

Hi Richard, When the instance of your NSTextField subclass becomes first responder, you have access to the NSText object (the field editor) and I believe you can use its methods to select the text.

In general, if the text field doesn’t look editable until you “click to edit” (click #2 in the above, because I assume you don’t have click #1 at all in your app), then I think it’s fine for it to do a select all (or select something-predefined-like-Finder-does), because there’s no expectation from the appearance of the text that you might start with a drag-to-select-and-begin editing. In your case, where the “click to edit” behavior is already expected by users, I don’t see a big problem in what you’re proposing, though I think the *classy* solution would be to have a subtle difference in appearance in the text field when a click is needed to start editing, even if it flies under the perceptual radar of experienced users. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

The text field contains a numeric values like 58.35 or -2.41 or something similar. The gold standard for this type of application and this type of data is to have the contents of the text field selected when the user clicks on it so he or she can quickly key in a new value to replace the existing value. Behavior other than this is a pain and not appreciated by typical users of this application. Finder does something similar when renaming files and folders. The first click selects the file or folder. The next click selects the name of the file or folder ready for replacement. The third click will place the insertion point somewhere within the text field ready for fine grain editing of the file or folder name. --Richard Charles ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Incidentally — this is the part where we make you sorry you asked the question — what are you trying to achieve here? Auto-self-selecting text fields are an incredibly annoying UI, if the user is ever likely to want to select only part of the field. If you’re selecting everything to allow it to be copied easily, then a “Copy” button next to the text is probably a better idea. If you’re selecting everything in order to cause it to be deleted on the first keystroke, a “Clear” button (probably an “x” icon button) similar to iOS search fields is probably a better idea. That is, if at all possible, augment the standard behavior, don’t change it. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Update
The documentation for -[NSTextField selectText:] states "If the receiver isn’t
in some window’s view hierarchy, this method has no effect.”
I have verified that the text field is in the window’s view hierarchy. I have
verified that -[NSTextField selectText:] is getting called. (Actually it is
getting called twice, once by the frameworks for some reason, and once by me.)
Calling the method -[NSTextField isSelectable] returns YES.
It appears that -[NSTextField selectText:] is broken in 10.10 Yosemite. It just
does not work.
