Use of Nspathcontrol to Represent Virtual Path

Customise NSPathControl

I found the solution and posted it on github.
I subclassed from NSPathControl. It's pretty simple actually.

NSPathControl and Auto Layout

Solution

Sorry, I guess I asked to fast.

I got it working like this:

NSPathControl subclass

- (NSSize)intrinsicContentSize {
    return NSMakeSize(NSViewNoInstrinsicMetric, NSViewNoInstrinsicMetric);
}

SwiftUI NSPathControl open finder location when clicking icons

You can use the Coordinator pattern with NSViewRepresentable:

struct PathView: NSViewRepresentable {
    var configuration = { (view: NSPathControl) in }
    
    func makeNSView(context: NSViewRepresentableContext<PathView>) -> NSPathControl {
        let pathControl = NSPathControl()
        pathControl.target = context.coordinator
        pathControl.action = #selector(Coordinator.action)
        return pathControl
    }
    func updateNSView(_ nsView: NSPathControl, context: NSViewRepresentableContext<PathView>) {
        configuration(nsView)
    }
    
    func makeCoordinator() -> Coordinator {
        return Coordinator()
    }
    
    class Coordinator : NSObject, NSPathControlDelegate {
        @objc func action(sender: NSPathControl) {
            if let url = sender.clickedPathItem?.url {
                print(url)
                NSWorkspace.shared.selectFile(url.path, inFileViewerRootedAtPath: url.path)
            }
        }
    }
}

Note: I'm not actually using any NSPathControlDelegate methods -- that's just to show that it could be extended to be a delegate as well

How to set the URL of a NSPathComponentCell?

• If you want to display a valid URL, just set the URL property of the NSPathControl instance with an NSURL object
• If you want to display relative paths or other invalid URLs, look at the Apple sample code NSPathControl Basics
