| Description:
Design, implement and test a basic Quiz GUI application. This
application will use the following classes used in Assignment
7. You are given the following classes: Question, MultiChoiceQuestion,
TrueFalseQuestion,
Choice and ArrUtil
(you also need EasyIn
which you already have. NOTE: That EasyIn will only
be needed to compile your application because your quiz classes
already use it. YOU ALSO NEED
YOUR Quiz.java FROM THE PREVIOUS ASSIGNMENT).
In addition, you will need these classes: QuizGUI.java,
NewQuizDialog.java,
TFQuestionForm.java,
QuestionForm.java,
RunQuizForm.java.
You will only need to modify QuizGUI.java and NewQuizDialog.java.
Once completed, the instructor will use your classes in a program
to test the classes' implementations.
To view the final
application, download this jar file, QuizGUI.jar
and run
java -jar QuizGUI.jar
at the command prompt. Note: you must have Java 1.2 or higher
for this to work.
1. (QuizGUI) Add a menu item to the "File" menu labeled
"Exit". You need to add the appropriate event handler
to this menu item that terminates the application when a user
click on this item. This will look as follows:
To add a menu item to a menu you need to use the menu's "add(
menuItem )" component.
2. (QuizGUI) Add a menu to the application titled "Help"
(You can see this in the above picture). You need to add this
Menu to the application's MenuBar before the method, "setMenuBar(
MeunBar )" is called in the application's constructor.
The menu bar is called "menuBar". Help should
also have a menu item called "About". You need
to add the appropriate event handler to the "About"
item, so when it is clicked on it displays a dialog with information
about the application. You do this by registering an event listener,
ActionListener, to the "About" menu item. The
dialog should have a label and one button titled "OK".
When it is clicked on the dialog should be disposed. You should
use JOptionPane's static method showMessageDialog() to
create and display this dialog. Here is what your dialog should
look like:
You need to include "CIS 226", "Introduction
to Java Programming", "Fullerton College" and
your name.
The menu that calls this dialog should look as follows:
Note: menu and menu items should be private members of the
class.
3. (NewQuizDialog) You are given a basic skeleton class, NewQuizDialog,
you need to add the components to this class to create a dialog
looks as follows:
You will need to add a JLabel, JTextField, and
a JButton titled "OK". I have provided some
code that declares these components. If you choose not to use
my code, the other implementation will be up to you to complete.
You will need to lay your components out so the dialog looks
identical to the one displayed. Hint: you will need additional
help from JPanels.
This dialog is called automatically when the application is
started. I have done this for you. You need to implement the
specs to make it functional.
4. (NewQuizDialog) Add the appropriate handler to the "OK"
button to allow users to click on the button and have the handler
submit the quiz's title to create a quiz. Hint: You need
to register and actionListener to the button, i.e. okBtn.addActionListener(
listener ), and implement the ActionListener's declared
method, actionPerformed( ActionEvent ).
5. (NewQuizDialog) Add the appropriate handler to the "OK"
button to allow users to press on any key and have the handler
submit the quiz's title to create a quiz. Hint: You need
to register and actionListener to the button, i.e. okBtn.addKeyListener(
KeyListener ), and implement the KeyListener's declared
method(s), keyPressed( KeyEvent ). If you use the listener's
adapter classes you will only need to implement the methods
needed. However, if you use the KeyListener interface, you will
have to implement all methods declared in the interface.
6. (NewQuizDialog) Add the appropriate handler to the text
field to allow users to press the "ENTER" key and
have the handler submit the quiz's title to create a quiz.Hint:
You need to register and actionListener to the button, i.e.
titleTxtFld.addKeyListener( KeyListener ), and implement
the KeyListener's declared method(s), keyPressed( KeyEvent
). If you use the listener's adapter classes you will only
need to implement the methods needed. However, if you use the
KeyListener interface, you will have to implement all methods
declared in the interface.
7. (NewQuizDialog) Add the appropriate code to the private
method "handleBasicEvent()" so this dialog
is hidden if an error occurs, then displays another error dialog
by using JOptionPane.showMessageDialog(), then when the
error dialog is terminated, you should display the New Quiz
dialog again. Your error dialog should look as follows:
The application looks as like:
Hint: you can hide dialogs with setVisible(
boolean ) method from the java.awt.Component class. The Component
class is a parent class of JDialog.
8. EXTRA CREDIT (QuizGUI) Change the look and feel of this
application to a windows look and feel.
I have taken care of all of the code that handles the tree
control as well as the code that displays different forms in
the right-hand side of the split pane. If you modify my code,
it is your responsibility to fix anything that doesn't compile.
Your source code is marked with comments:
/*********** TODO 1
***************/
YOUR CODE WILL GO HERE
/*********** END TODO 1 ***************/
Where TODO # represents the task number for this assignment.
This is an advanced GUI application, so I don't expect you to
know everything about it. However, I do expect you to be able
to modify the code I have supplied you with.
Objectives:
* Be able to create GUI components.
* Understand Abstract Data Type (ADT)
* Understand Inner classes and event handling
* Understand menus and menu items
* Understand Object Oriented Programming concepts of encapsulation
and polymorphism
