    • setUpParameterDefaults

      protected void setUpParameterDefaults()
      Description copied from class: GenericGraphApplet
      This method, which is empty in the GenericGraphApplet class, can be defined in a subclass to set default values for applet params that are different from the ones provided in this class. The method should create a new HashTable, assign it to the instance variable parameterDefaults, and then add name/value pairs to the hash table. This method is called at the very beginning of the init() method.
      Overrides:
      setUpParameterDefaults in class GenericGraphApplet
    • setUpCanvas

      protected void setUpCanvas()
      Description copied from class: GenericGraphApplet
      This method is called by mainPanel() to set up the display canvas and add it to the main panel. The canvas already exists in the member variable canvas when this method is called. This method adds only a set of axes to the canvas, sets the mainController to report errors using the canvas, and adds the canvas to the CENTER of the main panel. This method processes applet parameters "UsePanner", "CanvasColor", "UseMouseZoom", and "UseOffscreenCanvas". Typically, this method will be overridden in subclasses to add more Drawable items to the canvas. In this case, super.setUpCanvas() should be called first.
      Overrides:
      setUpCanvas in class GenericGraphApplet
    • setUpLimitsPanel

      protected void setUpLimitsPanel()
      Description copied from class: GenericGraphApplet
      This method sets up the limit control panel and adds it to the main panel. The limit control panel already exists when this method is called and is stored in the member variable limitsPanel. The applet parameters "TwoLimitsColumns", "UseSetLimitsButton", "UseZoomButtons", "UseEqualizeButtons", "UseRestoreButton", "PanelBackground", and "LimitsOnLeft" are processed. The limits panel is set to report its errors using the display canvas.
      Overrides:
      setUpLimitsPanel in class GenericGraphApplet
    • setUpBottomPanel

      protected void setUpBottomPanel()
      Description copied from class: GenericGraphApplet
      This method checks the applet parameter "UseFunctionInput". If the value is anything but "no", then a panel is created that contains an ExpressionInput (stored in the member variable functionInput) and possibly a ComputeButton and lable for the input box. This panel is a JCMPanel using BorderLayout. In is stored in the member variable inputPanel and is added to the SOUTH position of the mainPanel. The method also processes applet parameters "Function", "UseComputeButton", "ComputeButtonName", and "FunctionLabel". The ComputeButton, if it exists, is stored in the member variable computeButton. Note that nothing at all is done by this method if the value of the applet parameter "UseFunctionInput" is no.
      Overrides:
      setUpBottomPanel in class GenericGraphApplet
    • setUpMainPanel

      protected void setUpMainPanel()
      Description copied from class: GenericGraphApplet
      This method is called to set up the main panel of the applet. The main panel object, of type JCMPanel, already exists in the variable mainPanel when it is called. It begins by calling setUpParser() and setUpExampleMenu(). This method processes applet parameters "Insets", "BackgroundColor", and "ForegroundColor" to set the gap and colors of the panel. It creates a DisplayCanvas and, if the applet parameter "UseLimitsPanel" is not equal to "no", it creates a LimitControlPanel. The coordinate limits are set using the "Limits" applet param, if presetn. This method assigns the Controller from the mainPanel to the member variable mainController. It then calls setUpBottomPanel(), setUpTopPanel(), setUpCanvas(), addCanvasBorder(), and, if there is a limits panel, setUpLimitsPanel(), in that order. Finally, if the value of the applet parameter "LoadFirstExample" is not "no", and if any examples were specifed, then the first ewxample is loaded.
      Overrides:
      setUpMainPanel in class GenericGraphApplet
    • doLoadExample

      protected void doLoadExample(String example)
      Description copied from class: GenericGraphApplet
      This method is called when the user loads an example from the example menu (if any). The parameter is the string that defines the example. By default, this method does nothhing. It should be overridden to load the example.
      Overrides:
      doLoadExample in class GenericGraphApplet
    • stop

      public void stop()
      Description copied from class: GenericGraphApplet
      Releases the resources used by the display canvas when the applet is stopped.
      Overrides:
      stop in class GenericGraphApplet
