• #background=(value) ⇒ Vedeu::Colours::Background included from Presentation::Colour

  Allows the setting of the background colour by coercing the given value into a Vedeu::Colours::Background colour.

• #colour ⇒ Vedeu::Colours::Colour included from Presentation::Colour
• #colour=(value) ⇒ Vedeu::Colours::Colour included from Presentation::Colour

• #foreground ⇒ Vedeu::Colours::Foreground included from Presentation::Colour

  When the foreground colour for the model exists, return it, otherwise returns the parent foreground colour, or an empty Vedeu::Colours::Foreground.

• #foreground=(value) ⇒ Vedeu::Colours::Foreground included from Presentation::Colour

  Allows the setting of the foreground colour by coercing the given value into a Vedeu::Colours::Foreground colour.

• #initialize(attributes = {}) ⇒ Vedeu::Null::View constructor

  Returns a new instance of Vedeu::Null::View.

• #position? ⇒ Boolean included from Presentation private

  Returns a boolean indicating the model has a position attribute.

• #render_colour ⇒ String included from Presentation private

  Renders the colour attributes of the receiver and yields (to then render the styles).

• #render_position ⇒ String included from Presentation private
• #render_style ⇒ String included from Presentation private

  When the style for the model exists, return it, otherwise returns the parent style, or an empty Presentation::Style.

• #style=(value) ⇒ Vedeu::Presentation::Style included from Presentation::Styles

  Allows the setting of the style by coercing the given value into a Presentation::Style.
