Signals

Your .NET objects can define signals.

[Signal("signalName")]
public class NetObject
{
}

Your signals can also declare parameters.

[Signal("signalName", NetVariantType.String, NetVariantType.Int)]
public class NetObject
{
}

You can raise signals from .NET.

public void YourMethod()
{
    netObject.ActivateSignal("signalName", "param", 3);
}

You can attach signal handlers from both .NET and QML.

public void YourMethod()
{
    app.AttachToSignal("signalName", new Action<string, int>((param1, param2) =>
    {
        Console.WriteLine("Signal raised!");
    }));
}

import YourApp 2.1

YourNetObject {
    onSignalName: function(param1, param2) {
        console.log("Signal raised!")
    }
}
