Re: Context Menu and first responder targets

Hi Eyal, I believe the target for a pop-up menu is the view that you pass in that method, at least initially. If there is an established responder chain from that view to other responders (up to and including First Responder) then the menu items should reach their target. But it’s pretty easy

In the “old days”, your app could periodically call UpdateSystemActivity( UsrActivity ) to prevent the screensaver kicking in. This has been deprecated since 10.8, but the header for that function says it can be replaced by IOPMAssertionCreateWithName(). I haven’t looked at that in detail or

You can make your app trigger a command-line program and pass params using NSTask. It’s not difficult to use. But in this case you might want to negotiate this with the user - apps that just go ahead and change MY system preferences are being user-hostile to say the least. —Graham > On 28

Increasing stack size of NSDocument's open file thread

Hi all, I’m wondering if there’s a way to increase the stack size of the thread that opens my NSDocument in the background. NSThread has a -setStackSize: method which would work, but it must be set prior to starting the thread. The problem is I don’t start the thread - Cocoa does. By the time
