module Fox
  #
  # An FXPseudoMouse object provides a simple means to operate widgets
  # programmatically, to aid test driven design. An FXPseudoMouse instance
  # can be pointed at an FXObject and will manage the sending of events to
  # it.
  #
  # For example:
  #
  #   canvas = FXCanvas.new(...)
  #   pm = FXPseudoMouse.new(canvas)
  #   pm.doLeftButtonPress # sends a SEL_LEFTBUTTONPRESS message to the canvas
  #
  class FXPseudoMouse < FXObject
