More idiomatic way to work with events

[lschmierer]

How can I access event struct fields without accessing _ptr?

connectKey(signal: "key_press_event") { _, event in
    let event = event._ptr.pointee
    debugPrint(event.keyval)
}

Swift doesn't support C-style unions such as GdkEvent, so there is no corresponding Swift wrapper with more idiomatic properties at the moment. I'll have a think if there is a way to teach gir2swift some magic to work around this ...

With SwiftGtk 3.24.17 and gir2swift 10, you can now access GdkEvent fields directly from Swift. Also, you probably want to use onKey or onKeyPress instead of connectKey, e.g.:

        widget.onKeyPress { widget, event in
            let key = event.keyval
            let hw = event.hardwareKeycode
            // ...
        }

        canvas.onKey(event: .keyPressEvent) { widget, event in
            let key = event.keyval
            let hw = event.hardwareKeycode
            // ...
        }
