Take a look at this simple code:
import Cocoa
import SwiftUI
struct DemoView: View {
var body: some View {
Text("Click me!")
.onTapGesture {
print("Clicked")
}
}
}
class FlippedView: NSView {
override var isFlipped: Bool {
return true
}
}
class ViewController: NSViewController {
override func viewDidLoad() {
super.viewDidLoad()
let stackView = NSStackView()
stackView.orientation = .vertical
stackView.alignment = .leading
stackView.spacing = 0
stackView.translatesAutoresizingMaskIntoConstraints = false
let hostView = NSHostingView(rootView: DemoView())
stackView.addArrangedSubview(hostView)
let scrollView = NSScrollView()
scrollView.translatesAutoresizingMaskIntoConstraints = false
let flippedView = FlippedView()
flippedView.addSubview(stackView)
scrollView.documentView = flippedView
view.addSubview(scrollView)
NSLayoutConstraint.activate([
scrollView.topAnchor.constraint(equalTo: view.topAnchor),
scrollView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
scrollView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
scrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
])
}
}
I need my scroll view to start at the very top, so i put it inside a flipped document view.
But now .onTapGesture does not fire.
