SwiftUI NSPathControl open finder location when clicking icons-CodePudding

I've wrapped NSPathControl for use in my Mac OS SwiftUI app but I can't work out how to make the sizes of the path smaller or how to get the individual paths to open the location in Finder when clicked.

Here is the wrapper:

struct PathView: NSViewRepresentable {
    typealias pathViewNSView = NSPathControl
    var configuration = { (view: pathViewNSView) in }
    
    func makeNSView(context: NSViewRepresentableContext<PathView>) -> NSPathControl {
        pathViewNSView()
    }
    func updateNSView(_ nsView: NSPathControl, context: NSViewRepresentableContext<PathView>) {
        configuration(nsView)
    }
}

I use the view like this:

PathView { view in
    view.url = URL(fileURLWithPath: "/Volumes/Users/myfolder", isDirectory: true)
}

I know to use NSWorkspace.shared.selectFile to open the path in Finder but not sure how to do this with the wrapped NSPathControl.

CodePudding user response：

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
