Current version=4

JComponentWithEvents.class downloads:
Current download: JComponentWithEvents.class (v4)
Also available in a zip file: JComponentWithEvents.zip (v4)
EventsDemo
- EventsDemo.java
- EventsDemo.jar
  - To create this jar file:
    1. Create "classes" directory
    2. Copy all necessary class files into classes directory
    3. Create manifest
      1. Must live in top-level of classes directory
      2. Delete any pre-existing manifest file!
      3. Case-sensitive, space-sensitive, and must end in a blank line!
      4. Main-Class should be the class where your "main" method resides
      5. Here is our manifest.txt file (note that it ends with a blank line!)
        Main-Class: EventsDemo
    4. Create the jar file
      1. Run command shell and cd to classes directory
      2. Run this command:
        jar cvfm MyProgram.jar manifest.txt .
        (Don't forget that trailing dot!)
        You may have to specify the full path to your java installation, something like this:
        "C:\program files\Java\jdk1.5.0_12\bin\jar" cvfm MyProgram.jar manifest.txt .
- EventsDemo.html (as an applet using the jar file)!
  - To create this html page:
    1. Create the jar file as above, but also include the file JComponentWithEventsApplet.class
    2. Use this html to run the applet (changing "EventsDemo" to your application's name in both places!):
```
 <html>
   <head>
     <title>My Graphics Applet</title>
   </head>
   <body bgcolor="#BBBBBB">
     Here is my graphics applet:
     <hr>
     <applet code="JComponentWithEventsApplet.class" archive="EventsDemo.jar" width="500" height="400" >
          <param name="ComponentClass" value="EventsDemo">
     </applet>
     <hr>
     And there was my graphics applet!
   </body>
 </html>
```
    3. Place the applet on a web server (note: the applet can only access files on that same web server!)
Previous downloads: v1, v2, v3

Change Log

Planned for v5:
- javadoc documentation
- improved exception handling due to file + reflection security exceptions in applet mode
v4:
- kinder, gentler version checker (in background so app still runs passably well with old version)
- non-final helper methods (getFileScanner, etc) (added on 20-Dec-09)
- getResourceAsStream + resource-friendly image and sound loading
- loadBufferedImage (resource-friendly) and saveBufferedImage methods
- more key constants:
  SPACE, BACK_SPACE, ENTER, ESCAPE, SHIFT, CAPS_LOCK, CONTROL, ALT
v3 (1-Oct-08)
- field modification check in paint
v2 (27-Sep-08)
- version checking at "launch"
- more responsive timer

- key constants:
  DELETE, HOME, PAGE_UP, PAGE_DOWN, END, F1, F2, ..., F12
