Re: How to: NSPopover Refuse First Responder?

[Andy Lee]

I always think of more to say *after* I hit Send...

I haven't tried spelunking in iTunes, but I wouldn't be surprised if it doesn't 
use NSPopover. You might want to try an alternative like Matt Gemmell's 
MAAttachedWindow: . I don't know if it has the 
same issues or not, but worth a look I think.

Worth a try but I have a feeling even this wouldn't be enough, because the 
popover's window could still become key window even if no view within accepts 
first responder. I suspect this is why it didn't help to have the NSPopover 
object refuse first responder.

It would be nice if there were a way to get the popover's window to refuse 
first responder. I fiddled briefly with Apple's NSPopover sample app and 
haven't found a way yet to do this. Unfortunately, the window is an instance of 
a private class (_NSPopoverWindow), which means you don't get a chance to 
subclass it and override canBecomeKeyWindow.

The opacity of NSPopover is very reminiscent of NSDrawer.

I think you'll need to ensure that none of the views in the popover accept 
first responder, which is a pain to do (and if they need to become first 
responder under some circumstances, might be impossible in the current 
implementation).

File a bug asking for something like -becomesKeyOnlyIfNeeded on NSPopover. The 
API is currently too limited.

Re: How to: NSPopover Refuse First Responder?

Hmm. I can think of reasons why this might not work, but it's worth a shot: 
Have you tried subclassing NSPopover and returning NO from 
-acceptsFirstResponder?

Yes, I tried that and tested that it was returning NO.  It didn't work.

How to: NSPopover Refuse First Responder?

[Brad Stone]

I'm trying to replicate the NSPopover functionality that the new iTunes has and 
I'm 99% there.  The las problem I'm facing is when the NSPopover appears it 
steals the firstResponder status from the NSSearchField so the user's typing 
gets interrupted when the popover appears.  I tried giving the firstResponser 
status back after the popover appear but all that does is mess up the user's 
typing.  

How can I have a popover appear but have the NSSearchField never relinquish 
it's firstResponder status or have the NSPopover refuse firstResponder?

Thanks
