Constructor Details

#initialize(origin = CGPoint.new, size = CGSize.new) ⇒ CGRect

Returns a new instance of CGRect.

Parameters:

  • origin (CGPoint, #to_point) (defaults to: CGPoint.new)
  • size (CGSize, #to_size) (defaults to: CGSize.new)

  super(origin.to_point, size.to_size)
end

Returns:

#size ⇒ CGSize, #to_size

Class Method Details

.ax_value ⇒ Number

Returns the number that AXAPI uses in order to know how to wrap a struct.

Returns:

  • (Number)

Instance Method Details

#contains?(inner) ⇒ Boolean

Whether or not the receiver completely encloses the inner rect

On MacRuby this is equivalent to calling NSContainsRect().

Parameters:

Returns:

  • (Boolean)

def contains? inner
  ox = origin.x; oy = origin.y; ow = size.width; oh = size.height

  inner = inner.to_rect
  ix    = inner.origin.x;   iy = inner.origin.y
  iw    = inner.size.width; ih = inner.size.height

  if iw.zero? || ih.zero?
    false
  else
    (ox <= ix)               && (oy <= iy)               &&
    ((ox + ow) >= (ix + iw)) && ((oy + oh) >= (iy + ih))
  end
end

#flip! ⇒ CGRect

Treats the rect as belonging to one co-ordinate system and then converts it to the other system

This is useful because accessibility API's expect to work with the flipped co-ordinate system (origin in top left), but AppKit prefers to use the cartesian co-ordinate system (origin in bottom left).

Returns:

def flip!
  frame         = ::NSScreen.screens.first.frame
  screen_height = frame.origin.y + frame.size.height
  self_max_y    = self.origin.y + self.size.height
  origin.y      = screen_height - self_max_y
  self
end

#inspect ⇒ String

Return a nice string representation of the rectangle

Overrides Object#inspect to more closely mimic MacRuby Boxed#inspect.

Returns:

#to_rect ⇒ CGRect

Returns the receiver, since the receiver is already a CGRect
