FB 4 Internationale Media and Computing MeSoII: Media Software II Sommersemester 2003

This week we will finish off the Application set of tutorials with Part 3: Receiving Input with Text Fields and Check Boxes, and Event Handling Basics. We are now going to get that DiverLog finished up! Good luck!

Read the planning section. Yes, there are a lot of usability problems with this interface. Those who are bored should see if they can come up with a better layout. Include all the variables in your Diver program that correspond to the elements on the screen. Can you explain the names chosen for the variables? Take a guess!

1. Set up the constructor, and then create the storage for all the labels and data. Now do the checkbox and the buttons. Now make the panels and add them to the layout. Patience, if you try and compile now you will get lots of errors! This does not mean that you have done something wrong, it just means that you haven't completed everything yet. Copy in the code for creating each of the panels, and now you can compile. It should be beautiful, but pretty useless, as it does nothing.
2. Read the section on Interfaces and Event Handling. Put in all the listeners for your fields and buttons.
3. Now, can you get it to work? There is a lot of detail in the last sections, try your best to get through, as this gives you a lot of insight back into Java.
4. Bored? Completely and utterly bored? Add a "Save" and a "Restore" button, and implement the functionality to save and restore the data entered! Or you can go on and do the fourth tutorial in this series about files.

The URL to your report, which will describe what you did during the exercise and include links to your code, is due in email box of your instructor by 8.00 next Wednesday. Do not forget to put your names on the top of the report! It is also a good idea put the number of the exercise somewhere in the title of your report.... When you send the URL of the report to your instructor, always include your partner in the CC. That way we don't get either 2 emails or none, because each or your thought the other was sending it. This has the added advantage that when we answer you, we can immediately answer both of you without having to look up the email account of your partner.
