Method Detail

setUpParser

protected void setUpParser()

Override this to create the animator and add its variable to the parser.

Overrides:

setUpParser in class GenericGraphApplet

setUpBottomPanel

protected void setUpBottomPanel()

Overridden to add the sliders at the bottom of the applet.

Overrides:

setUpBottomPanel in class GenericGraphApplet

setUpCanvas

protected void setUpCanvas()

Overridden to add the graph to the canvas and do other chores.

Overrides:

setUpCanvas in class GenericGraphApplet

setUpLimitsPanel

protected void setUpLimitsPanel()

add animator inputs to limits panel

Overrides:

setUpLimitsPanel in class GenericGraphApplet

doLoadExample

protected void doLoadExample(java.lang.String example)

This method is called when the user loads an example from the example menu (if there is one). It overrides an empty method in GenericGraphApplet. For the AnimatedGraph applet, the example string should contain an expression that defines the function to be graphed. This can optionally be followed by a semicolon and a list of four to nine numbers. The first four numbers give the x- and y-limits to be used for the example. If they are not present, then -5,5,-5,5 is used. The next three numbers specify the minimum value for the parameter, the maximum number, and the number of intervals in the animation. The eigth number, if present, specifies the starting loop style for the animation with the following code: 0 for once-through, 1 for loop, and 2 for back-and-forth. The ninth number, if present, tells whether to start the animation immediately upon loading. If it is 1, the animation is started. If it is not specified or is any value other than 1, the animation is not started.

Overrides:

doLoadExample in class GenericGraphApplet

Parameters:

example - expression string for function to be graphed

stop

public void stop()

stop animator when applet is stopped

Overrides:

stop in class java.applet.Applet

setUpMainPanel

protected void setUpMainPanel()

Set up the main panel. Calls GenericGraphApplet to do the heavy lifting, then makes sure that the buttons get their correct foreground colors.

Overrides:

setUpMainPanel in class GenericGraphApplet
