def element
  render("text_drawable", [to_calzini_hash])
end

#html_element ⇒ Object

Usually we query by ID, but for TextDrawable it has to be by class. That's how needs_update!, etc continue to work.

def items_to_display_children(items)
  return [] if items.nil?

  items.map do |item|
    if item.is_a?(String)
      item
    else
      Scarpe::Webview::DisplayService.instance.query_display_drawable_for(item)
    end
  end
end

#to_calzini_hash ⇒ Object

Calzini renders based on properties, mostly Shoes styles. To have Calzini render this for us, we convert to the format Calzini expects and then let it render. See Webview::Para for the specific Calzini call.
