Question about mac catalyst corner radius

[iDevelopper]

Hello Leo,

Can I ask you where and/or how to find information about the windows corner radius used on macOS (via mac catalyst) ?

May be a private api method.

I allow myself to ask you this question because I can find absolutely nothing on the subject.

Thanks.

Hello, do you mean the macOS window corner radius? That is the default look that NSWindow has. If you want a custom shape, you can check this old example, but accessing the underlying NSWindow is not simple, and is private API. You can see how I obtain the NSWindow here:

LNPopupController/LNPopupController/LNPopupController/Private/UIView+LNPopupSupportPrivate.m

Line 225 in 8fb8edd

//Obtain the actual NSWindow object

Those are just the instance variables (ivar) that are exposed. If you want to find the private ivars or methods/properties, you should use fp_methodDescription and fp_ivarDescription in the debugger like so:

po [hostingWindow fp_methodDescription]

of in debugger in Swift context:

po hostingWindow.value(forKey: "fp_methodDescription")

Sorry, no idea why it isn’t working for you.

If it works for you with the same sample project and the same version of Xcode (13.0?), It will work for me. I will look. Anyway, thank you for all 👍☺️

Yes, it worked for me. That’s how I found those private keys.
