Comp 152 Project 3: Windowed Programming

Due: Oct 30th at 11:55pm

Objective:

The high level objectives of this lab are:

• To use event driven programming.

• To use swing to build a program with a graphical interface.

• To practice inheritance again.

• To implement an interface.

• To use files again (a few of you told me that you needed more practice with them)

What you must do:

• three text fields with labels telling the user what they are
• make the third text Field be actually a JPasswordField
• A JComboBox (yes you will have to look this one up) whose choices should be populated with lines from the Proj3SampleData.txt file.
• one set of Radio buttons with a mutually exclusive choice
• at least three checkboxes.
• one labeled slider with values from 0-1023. Make the initial value 0 when the program starts.
• In a separate panel with a separate layout manager
• three buttons:
• one for save
• one for clear
• one for load

1. The Save button must save the contents of all of the textboxes, The combo box, the radio buttons and each of the checkboxes, and the slider in a file.
   
2. The clear button should clear all of the controls, removing checks and selections and text and returning the slider to a zero value. The combo box should be set to no text and no selection.
3. The load should load up the saved file and display its contents in the window

Extra Requirements:

You must satisfy the following constraints on your program

• Your program should be well commented

• No one method may be longer than 25 lines  of code long (Lines with only braces on them don't count. Since comments and white space aren't code, they do not count either.)

• One of your classes must extend the JFrame class

Submitting:

When your program is ready, you need to write a readme.txt file that provides me the following information:

• Your name

• The name of your java files (and the names of any extra non-public classes that are contained in the file.)

• The implementation decisions that you made. Why did you solve the problem the way that you did?

• Directions on running and using your program. Especially anything that might not be the same for all students. Also tell me what file name you used and the format you are saving the data (for example are the textbox data first? or the slider? how are you storing the checkboxes? as true and false? zero and one or something else.)
  

• And any problems or bugs left in your program. If your program doesn't quite work in some situations, tell me about it. If your program doesn't run or compile, I want to know that before I try.
