Re: Set focus on NSView in an NSMenuItem

Hi Peter!
Hi Hendrik!

I have almost the same setup as Hendrik: I use a NSSearchField in a 
menu. When the menu is opened I want the focus to go to the search 
field.

At first sight, the solution suggested by Peter appears to work fine. 
But something goes wrong. My search field misbehaves when I do this.

To be exact, the window's text editor does not respect the properties 
of my search field. E.g. if I hit return while editing, I get a 
newline in my search field. I however expect the search field's action 
to be called.

So I figured, I could delay setting the focus using 
performSelector:afterDelay: or using a NSTimer. I wouldn't know if 
this could alleviate the above described problem. The thing is: in 
both cases my selector only gets called after the menu is dismissed.

Hendrik, did you get this to work as expected?
Peter, could it be that the text editor is called upon too early?

Best,
Pierre
