private class PrisonerGame. OptionsDialog

extends java.awt.Dialog

implements java.awt.event.ActionListener

• width and height: the number of columns and rows of the board
• incentive: the gain when a dishonest prisoner chears an honest one
• threshold: the excess gain needed to motivate a prisoner to change behavior
• refresh frequency: the number of game turns between each refreshing of the game board display

The dialog also displays a warning that changing any of the above parameters (except the refresh frequency) restarts the game.

                                   java.lang.String title)

The constructor lays out the elements of the dialog box in a GridBagLayout and registers the needed listeners.

 private boolean applyOptions()

This method is used to apply the new options defined by the user. It tries to parse all text fields into int or double values. If any of these values are different from the current ones, the game is restarted by invoking the restartGame() method of the parent PrisonerGame instance. A format error in a number calls up an alert window. If only the refresh frequency was changed, the game is not restarted. The new value is just set and any running PrisonerGame takes it in stride (note that the setRefreshFrequency() method is synchronized). return The method returns false if an error occured

 public void actionPerformed(java.awt.event.ActionEvent e)

When the "OK" button is pressed, this method invokes the applyOptions() method. If the latter returns true or the "Cancel" button was pressed, the dialog box is disposed of.
