Re: Open a panel in secondary thread?
Don't know if this helps you but you can look into dispatch_sync and dispatch_async.

I guess there’s filtering or normalization going on at some stage (in software or in the DAC hardware itself.) But this is way out of my depth. I’d ask on the coreaudio-dev list, if it still exists, or the equivalent area of Apple’s dev forum. —Jens ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Open a panel in secondary thread?
You must run the panel on the main thread.

Re: Open a panel in secondary thread?
No you can’t one an NSOpenPanel on a secondary thread. UI elements must be on the main thread. —Rob > On Mar 21, 2020, at 1:05 PM, Gabriel Zachmann via Cocoa-dev > wrote: > > Is it possible to open an NSOpenPanel in a secondary thread? > > I create the thread like this: > >directoryScanThread_ = [[NSThread alloc] initWithTarget: self > selector: > @selector(scanDirectory:) > object: nil]; >[directoryScanThread_ start]; > > > But when I do: > >NSOpenPanel *oPanel = [NSOpenPanel openPanel]; > > it crashes at this point. > > In the docs, I found a hint that one should use > >lockFocusIfCanDraw > > but that is deprecated now. > > Any ideas will be highly appreciated. > > > Best regards, Gabriel > > > ___ > > Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) > > Please do not post admin requests or moderator comments to the list. > Contact the moderators at cocoa-dev-admins(at)lists.apple.com > > Help/Unsubscribe/Update your Subscription: > https://lists.apple.com/mailman/options/cocoa-dev/petrock%40mac.com > > This email sent to petr...@mac.com ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Isn’t the main thread meant for updating the UI? > On Mar 21, 2020, at 7:05 PM, Gabriel Zachmann via Cocoa-dev > wrote: > > Is it possible to open an NSOpenPanel in a secondary thread? > > I create the thread like this: > >directoryScanThread_ = [[NSThread alloc] initWithTarget: self > selector: > @selector(scanDirectory:) > object: nil]; >[directoryScanThread_ start]; > > > But when I do: > >NSOpenPanel *oPanel = [NSOpenPanel openPanel]; > > it crashes at this point. > > In the docs, I found a hint that one should use > >lockFocusIfCanDraw > > but that is deprecated now. > > Any ideas will be highly appreciated. > > > Best regards, Gabriel > > > ___ > > Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) > > Please do not post admin requests or moderator comments to the list. > Contact the moderators at cocoa-dev-admins(at)lists.apple.com > > Help/Unsubscribe/Update your Subscription: > https://lists.apple.com/mailman/options/cocoa-dev/zav%40mac.com > > This email sent to z...@mac.com ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Open a panel in secondary thread?
Is it possible to open an NSOpenPanel in a secondary thread? I create the thread like this: directoryScanThread_ = [[NSThread alloc] initWithTarget: self selector: @selector(scanDirectory:) object: nil]; [directoryScanThread_ start]; But when I do: NSOpenPanel *oPanel = [NSOpenPanel openPanel]; it crashes at this point. In the docs, I found a hint that one should use lockFocusIfCanDraw but that is deprecated now. Any ideas will be highly appreciated.
