Copy/Cut/Paste does not work on Mac

[stefanwagnerdev]

I use this along with https://github.com/badlogic/pi-diff-review
I noticed that copy paste does not work on Mac in the comment windows.

My current hack is to trigger the copy paste functions if the key is pressed.
This works but only for mac. I havent tested if the other platforms have the same problem.

class GlimpsePanel: NSWindow {
    override var canBecomeKey: Bool { true }
    override var canBecomeMain: Bool { true }

    override func performKeyEquivalent(with event: NSEvent) -> Bool {
        if super.performKeyEquivalent(with: event) {
            return true
        }
        if NSApp.mainMenu?.performKeyEquivalent(with: event) == true {
            return true
        }

        // Accessory/frameless panel mode can bypass normal menu key-equivalent routing.
        // Fallback to responder-chain edit actions for standard clipboard shortcuts.
        let modifiers = event.modifierFlags.intersection(.deviceIndependentFlagsMask)
        guard modifiers == .command || modifiers == [.command, .shift] else {
            return false
        }

        guard let chars = event.charactersIgnoringModifiers?.lowercased() else {
            return false
        }

        let action: Selector?
        switch chars {
        case "c": action = #selector(NSText.copy(_:))
        case "x": action = #selector(NSText.cut(_:))
        case "v": action = #selector(NSText.paste(_:))
        case "a": action = #selector(NSText.selectAll(_:))
        default: action = nil
        }

        guard let action else {
            return false
        }

        return NSApp.sendAction(action, to: nil, from: self)
    }
}
