# File 'lib/glimmer/swt/custom/shape/rectangle.rb', line 79

def absolute_point_xy_array
  [[absolute_x, absolute_y], [absolute_x + calculated_width, absolute_y], [absolute_x + calculated_width, absolute_y + calculated_height], [absolute_x, absolute_y + calculated_height]]
end

#include?(x, y) ⇒ Boolean

checks if drawn or filled rectangle includes the point denoted by x and y (if drawn, it only returns true if point lies on the edge)

Returns:

  • (Boolean)
