Is it possible to modify an existing gomponent?

Is it possible to modify an already created component (adding new childs, chaning atttributes, etc.)?

Thank you!

Hi @AxelRHD . Generally, the style of gomponents as seen in the examples is quite declarative, so you'd have to build your own components in a more imperative style if you need that. All you need to do is implement the gomponents.Node interface, and you can use your components everywhere, also with existing helpers and functions.

I hope that answers your question? 😊

I hope so. I am just a seasoned programmer. Maybe you can give a short example?

You could do something like:

type YourComponent struct {
    children []g.Node
}

func (c *YourComponent) AddChild(child Node) {
    c.children = append(c.children, child)
}

func (c *YourComponent) Render(w io.Writer) error {
    // Render however you want to the writer
    return nil
}

I see! Children is a slice of the included objects. I think, that will do it.

Thanks a lot!
