public class ControlPanel

extends java.awt.Panel

This class extends the java.awt.Panel class to form a panel which holds the buttons that control the animation of the algorithm.

In this particular application, it only consists of four image buttons, namely, run, stop, step, and skip.

Constructor Detail

ControlPanel

public ControlPanel(AlgAnimFrame frame,
                    java.lang.String algname)

Creates a panel to hold the control buttons of the animation tool.

Parameters:

frame - The parent window frame that contains this panel

algname - The algorithm name parsed from the applet parameter

Method Detail

refreshButtons

public void refreshButtons()

Perform a repaint() on each of the image buttons.

action

public boolean action(java.awt.Event e,
                      java.lang.Object arg)

Action handler for the buttons and choice buttons in the control panel.

Overrides:

action in class java.awt.Component

Parameters:

e - Event invoked

arg - Object that invokes the event

getRunButton

public java.awt.Button getRunButton()

Returns an instance of the run ImageButton, which is casted to java.awt.Button

Returns:

Run button to initiate the animation of the algorithm.

getStopButton

public java.awt.Button getStopButton()

Returns an instance of the stop ImageButton, which is casted to java.awt.Button

Returns:

Stop button to terminate the execution of algorithm.

getStepButton

public java.awt.Button getStepButton()

Returns an instance of the step ImageButton, which is casted to java.awt.Button

Returns:

Step button to trace through the execution of the algorithm. If the Run button has already been pressed, the execution mode will be switched from RUN to STEP.

getSkipButton

public java.awt.Button getSkipButton()

Returns an instance of the skip ImageButton, which is casted to java.awt.Button

Returns:

Skip button to bypass the animation of the algorithm.
