Assignment 10: Tasks

Due: 5:00pm, Friday, November 14. Value: 30 pts.

Using Swing, build an application that allows the user to manage a list of tasks to do. The window's appearance should be similar to the picture at right. To get this appearance, you can do the following.

• Create a JPanel with both a text field and the Add button inside it. Place the JPanel at the north edge of the window.

• Create a JList, wrap it in a JScrollPane, and place it in the window's center.

• Create a JPanel with just the Remove buton inside it. Place this JPanel at the south edge of the window.

The program you write should have the following behavior when executed.

• The user can enter a string in the text field at top and click the Add button. The string is added to the end of the list, and the text field becomes clear for adding another task.

• The user can select an entry in the list of tasks and click Remove. The selected entry should disappear from the list of tasks.

• The Remove button should be disabled whenever nothing is selected within the list. You can accomplish this by adding a ListSelectionListener to the JList and then using the JButton class's setEnabled method.

You'll want to use a JList, which we didn't see in class. In general, you should find the Java API documentation sufficient for learning how to use Swing classes. However, I have also created a simple program CSciClasses that illustrates the use of a JList.
