Instance Method Details

#*(mul) ⇒ Object

Return a new Wx::Point with the x and y values both multiplied by parameter mul, which should be a Numeric

# File 'lib/wx/classes/point.rb', line 23

def *(mul)
  self.class.new( (get_x * mul).to_i, (get_y * mul).to_i )
end

#+(arg) ⇒ Object

Return a new Wx::Point with the x and y values both increased by parameter arg. If arg is another Wx::Point, increase x by the other’s x and y by the other’s y; if arg is a numeric value, increase both x and y by that value.

  else
    Kernel.raise TypeError, "Cannot add #{arg} to #{self.inspect}"
  end
end

#-(arg) ⇒ Object

Return a new Wx::Point with the x and y values both reduced by parameter arg. If arg is another Wx::Point, reduce x by the other’s x and y by the other’s y; if arg is a numeric value, reduce x and y both by that value.

#/(div) ⇒ Object

Return a new Wx::Point with the x and y parameters both divided by parameter div, which should be a Numeric

def /(div)
  self.class.new( (get_x / div).to_i, (get_y / div).to_i )

#==(other) ⇒ Object
