Well, I had to try it in a test project. I don’t see *any* difference in appearance in the buttons, with acceptsFirstResponder YES or NO, regardless of window state, regardless of IB canvas or running application, *except* that colored highlights (the blue indicating a default button, or the blue menu indicator on a popup button) change to gray in an inactive window. This is with macOS Sierra. It’s possible that earlier iterations of the OS X UI did have an inactive appearance for buttons, and my feeble recollection is that this was so for a while in the 10.6-10.8 era, at least. Perhaps what I did at the time was disable the button when the window went inactive. > Nothing in the documentation of acceptsFirstMouse suggests such a thing. Well, the event parameter is allowed to be nil (and AppKit headers have been audited for nullability, so it’s not likely to be an oversight). _______________________________________________ Cocoa-dev mailing list (Cocoaemail@example.com) Please do not post admin requests or moderator comments to the list.
