module Fox
  #
  # An FXPseudoKeyboard object provides a simple means to operate widgets
  # programmatically, to aid test driven design. An FXPseudoKeyboard instance
  # can be pointed at an FXObject and will manage the sending of events to
  # it.
  #
  # For example:
  #
  #   textfield = FXTextField.new(...)
  #   pk = FXPseudoKeyboard.new(textfield)
  #   pk.doKeyPress     # sends a SEL_KEYPRESS message to the textfield
  #   pk.doKeyRelease   # sends a SEL_KEYRELEASE message to the textfield
  #
