A function that create button_device and set up

[t.tutiya]

I want to create a function that creates a button_device, sets up a handler function, and returns that object.

However, the following function gives me a compile error.

CreateLoudButton(Name:string, Handler: widget_message->void):button_loud = 
    Button:button_loud = button_loud:
        DefaultText := StringToMessage(Name)
    Button.OnClick().Subscribe(Handler)
    return Button

What am I doing wrong?
Thank you.

This should work :

my_custom_handler := class:
    Callback: type{_(:widget_message) : void}

    HandleOnClickEvent(Payload:widget_message):void=
        Callback(Payload)

your_ui_class := class():

    CreateLoudButton(Name:string, Handler: widget_message->void):button_loud = 
        Button:button_loud = button_loud:
            DefaultText := StringToMessage(Name)

        CustomHandler := my_custom_handler{Callback := Handler}
        Button.OnClick().Subscribe(CustomHandler.HandleOnClickEvent)

        return Button

I use this kind of setup literally in all my files, don’t know if it’s the right way to go, but it should work!
