    properties = stylename

#stylesheet=(new_stylesheet) ⇒ Object

Assigning a new stylesheet triggers restyle!.

Assigning a stylesheet is an alternative to returning a Stylesheet in the stylesheet method. Note that restyle! calls stylesheet, so while assigning a stylesheet will trigger restyle!, your stylesheet will not be picked up if you don’t return it in a custom stylesheet method.

Examples:


stylesheet = Teacup::Stylesheet[:main]
stylesheet = :main

Returns:

  • Teacup::Stylesheet

    self.view.restyle!
  end
end

#teacupDidLoad ⇒ Object

Instantiate the layout from the class, and then call layoutDidLoad.

If you want to use Teacup in your controller, please hook into layoutDidLoad, not viewDidLoad or windowDidLoad (they call this method).
