The important thing is that the frames are set inside the grouping. Updating
constraints should not cause any frames to be set, only

if i understand you correctly: you want to adjust the cursor in your view based
on state, but embedded controls should set the cursor independently. you might
try subclassing the controls in question, register a tracking area (for
controls that do not already have one, only) & define mouseEntere

It would remove one — and perhaps the only — re
erratum: in your context, initializing tracking w/ NSTrackingCursorUpdate &
defining cursorUpdate is probably more appropriate.
&, on further reflection, this technique does not inhibit the sending of
mouseMoved in the parent view.

Hi,
Yes, I realize that. But in this case, the root object obeys the new/alloc

varying times.
In this case, there was an old-school network manager, that used manual MM.
This was kept like that (by switching off ARC o

Try some bonehead debugging with NSLog(). Verify that toolbaritem is your
target item at that point, in particular, that it is not nil. If that seems to

There's a lot to be said for spreading lots of NSLog through your code. It's
amazing how many bugs you can nail down using this old-school form of debugging.

Jerry,
The example I was following comes from Stack Overflow and going something like
this within the custom toolbar item:
NSButton *button = [[NSButton alloc]init];
[button setImage:[NSImage imageNamed:@"StarEmpty"]];
[button setAlternateImage:[NSImage imageNamed:@"StarFull"]];
[button setImage

Andy,
I inserted code to check for nil images and image position, here is what I got:
// set the original and alternate images...names are “opposite"
NSImage *image = [NSImage imageNamed:@"StopButtonAlternateIcon”];
if(image)
{
NSLog(@"Setting 1st image for stop button");
[_button setImage

Oh well, it was worth a try, and at least you've confirmed some basic steps
*are* working.
From your previous message it sounds like you also checked self.toolbarItem and
it too was not nil (as it could have been if, for example, you'd forgotten to

Andy,
I discovered something that may lead to the real culprit. Using the debugger, I
checked the size of the image chosen by imageNamed method, it was choosing the
128x128 icon image, but my toolbar item buttons were 48x48. I changed the
toolbar item sizes to 32x32, same thing.
On Apr 23, 201
Based on your thought about setFrame: called multiple times, I do have some
interesting news, though not a full resolution: setFrameSize was getting
called repeatedly with the final size during the animation. I put logging
in setFrame{Size,Origin}: in the view whose constraints are altered. Here's
if a control changes rendering on entry, as well as the cursor, mouseEntered is
serviceable; if changing the cursor is the goal, cursorUpdate is clearer—better
practice. unfortunately, if views overlap mouseMoved is still sent to the
parent, which muddles the state directed adjustment anyway.

“or if you were trying to plug in the button during init, which is too early).”
That may be it, as I was setting the toolbar item’s view to the button in
init(). If not there then where?
