csjava Project FAQ (version 2) What is the csjava project? The csjava project is an open source software project aimed at developing fun and instructive software for Java and CS courses. It includes (but is not limited to) the design, implementation, testing, and documentation of programs related to: - image processing - multimedia programs (e.g. MP3/MPEG players) - speech generation - 2D animation - language and string processing code - helper code for beginning and intermediate (and beyond) CS courses - a MACM package (i.e. code useful for people taking MACM 101/201) - a parallel processing package - code for creating chat-bots that run on Jabber servers - demo/example code showing off fun/interesting/important aspects of CS - anything else related to CS and Java that a csjava developer wants to contribute! In a few weeks, we may also be be looking for help setting up some a parallel Knoppix system in the Surrey labs, and possibly even creating an SFU-specific distribution of Linux for education (e.g. based on Knoppix). We'll post to the mailing list when we know more. What is the current state of development? We've already created (and used in CMPT 125 and 225) some of the image processing code, namely TheMatrix. You can download the current release of the csjava.jar file here: https://sourceforge.net/projects/csjava/ (the current release is named "stimpy"). As you can see, there is not yet any documentation for how to use this. Any volunteers willing to write an introductory tutorial? :-) If I join, how much work is involved? Since this is a volunteer project, you can do as much or as little as you like. It's up to you. You can join and just watch and explore for a while to see if there's anything that interests you. Or you could volunteer to be the lead for one of the above sub-projects, which will require a little more commitment. But imagine the glory! :-) The most useful and interesting code will be included in future releases of the csjava project. If you are inactive on the project for a long time, you will probably be dropped from it. What if I have an idea for something else that I want to do for this project? Great! We welcome new ideas, especially if they are based on code that's already in the csjava package. Suggest your idea to the group mailing list, and see what people say. Or when its done, send a request for people to try out your code --- but keep in mind that most people will probably only want to try out code that is fun/interesting or does something useful for them. Getting other people to use (and improve) your code is strongly encouraged. How do I join? The first thing to do is to subscribe to the csjava-developers mailing list: https://lists.sourceforge.net/lists/listinfo/csjava-developer This is the place to ask questions, get help, propose new ideas, discuss design choices, announce new code for the project, etc. The project itself is on SourceForge, a website that hosts open source projects: https://sourceforge.net/projects/csjava/ How do I get started? To become an official developer listed on the project page, you must join SourceForge to get a username. This is free and easy. Once you've got your username, email it to me (tj...@sf...) and you will be added as a developer. The next step is to learn how to download code from the CVS tree. This has a bit of a learning curve, but it is very useful and learning how to use CVS now is good experience for future projects you may work on that use version control. What is the CVS tree? CVS is a popular version control system that keeps track of all the revisions to files in a project. All the csjava source code is stored in a CVS tree on SourceForge, and your first task is to get a CVS client up and running so that you can access the tree. If you want to browse the files in the tree, look at the csjava folder here: http://cvs.sourceforge.net/viewcvs.py/csjava What's a CVS client? Which one should I use? A CVS client is a program that runs on your computer, and it talks to the main CVS tree. You use the client to download code from the tree, and upload changes. Eclipse has an excellent built-in CVS client, and you are strongly encouraged to use that one. It is quite easy to use compared to many other CVS clients. You are not required to use Eclipse; you can use and IDE or CVS client you like. How do I set up the Eclipse CVS client? You must follow these steps carefully! CVS is notoriously finicky, and a single wrong character can result in bizarre and cryptic behaviour. But once you get it working, it's pretty good. - First, you must be part of the csjava project, i.e. your name must be on the developers list of the project (check https://sourceforge.net/projects/csjava/). If your name isn't there, then get a SourceForge name and get send it to one of the project administrators so you can be added to the project. - Second, run Eclipse and open the Window menu, then Show View, and then choose Other. Open the CVS folder, and select "CVS Repositories". - Third, add the csjava repository by clicking the icon for Add CVS Repository, and then fill in the form that pops up with the following information: Connection type: extssh User: your SourceForge user name Password: your SourceForge password Host: cvs.sourceforge.net Repository path: /cvsroot/csjava Select both "Use Default Port" and "use the repository identification string as the label". Double-check that you've entered everything correctly. - Fourth, if the previous step went well, you can now check out the CVS tree, or parts of it. Lets check out a copy of the csimage folder in the HEAD branch. First create a new Java project in Eclipse. Just create it, and don't add any files. Then in that project choose "import", and choose "Checkout Projects from CVS". The wizard will step you through checking out the project. I tried the previous steps, and it doesn't work. Help! As mentioned, CVS is tricky to set up at first. But it does work, and Eclipse makes using CVS about as easy is possible. The first thing you should do is check that you've typed all the CVS repository information correctly. A single mis-typed character will cause problems. Some errors may be due to temporary problems, such as a network delay. Thus, starting all over from the beginning is sometimes helpful. If you're stuck, email the csjava-developers list and ask for help. Be as specific as possible about why its not working. Give specific details, and error messages (if any!). What is updating? What is committing? In CVS terms, "updating" means updating your personal copy of the CVS tree. Committing is when you upload your changed version of a file to the CVS tree. Update frequently, and commit only when you have finished, tested changes. What rules should I follow when I start out using CVS? It takes some time to get familiar and comfortable with CVS, so when you first start out please don't modify any of the files in the HEAD branch. Make your package in the "developers" package, and practice there for a while until you get the hang of it. Who can commit what files? Anyone can modify any files. But please, don't modify files outside of your developer package without discussing your changes with others. This is especially important for code used by lots of other programs --- even small changes could break lots of code. When in doubt, please ask! You say the project is "open source". What does that mean? All the csjava source code is freely available to anyone to use or modify as they wish. The development is done on SourceForge, which is a hosting site for open source projects. Even code that does not end up in the main release will be made publicly available. Finally, this is a shared project that depends upon the care and good will of the developers. Many people depend on the code in this project, so strive to be helpful, cooperative, and considerate. And have fun! ------ End of Forwarded Message |

Thanks for your feed back, I was thinking the same thing about having a button bar someplace instead of having the buttons on top of the image, where they could obscure important information. To fix this and have a button bar inside the window would require a potentially major rewrite of the window-painting code (and potentially eliminate it altogether). Instead of drawing the image itself, it could pass the work off onto a JLabel object that shows an ImageIcon wrapped around the BufferedImage. Another option would be to have a JDialog hovering around the window someplace, where it could be moved easily. Just some thoughts. Let me know what you think when you have time. Daryl.

Daryl, This is a response to your message on the developers forum (copied at the end of the message). What's there looks good, and gives ideas for modifications: - the buttons are actually on top of the picture, which I think is rarely going to be what people want; better would be to have the buttons in a separate panel - some buttons are user-created, and some are built-in; I suggest that we make a serious easy-to-user built-in buttons such as "save", "load", and "close" that work in such a way that the user does not need to anything about JButtons or listeners; the user-created buttons require that the user need to know a little more, but it might be possible to further simplify the addition of user-created buttons Toby By: Daryl Van Humbeck - raceimaztion RE: Adding buttons extension 2005-04-25 09:51 **** UPDATE **** I've added support for a "save image" button. To enable it, just call enableSaveButton(). It automatically adds a button to the bottom of the window and adds an action listener to listen for mouse clicks. When clicked, it pops up a save dialog box that lets you choose where to save it and what to call it. It always adds it to the far left of the window, even if there are already buttons there. |

It should be in my csimage.demo.aktsai folder, I finished off the implementation idea since I got woken up by sunlight after an hour and a half of sleep. I'm too brain fried to test it properly right now, but I will write something to test it in the next few days; I decided to commit it now just so the idea can be seen and so any blatant problems can be found by other people. -Alex |
