[GJS] Gtk.ListBox(Row) - Example needed

[Thomas Siladi <thomas siladi gmail com>]

Hello JS-List!

I am trying to use "Gtk.ListBox" in my GJS-Application and it is showing the list with no content, even if I have set the Header with "this._listBoxRow.set_header (this._lBRGrid);" ("this._listBoxRow" is Gtk.ListBoxRow; "this._lBRGrid" is the Grid I want to add to the ListBoxRow)

So does someone know how to make an useful ListBox with a Header and would like to share his/her code with us?

Thanks in advance!
