Help with Java Application. My splash screen will not display and I can't get my save button to work.?
A simple version with splash screen %26amp; working save button (you will need Java SE 6. To run the program, use this command: "java -splash:splash.jpg MeasurementsPanel", where "splash.jpg" is your picture for the splash screen. If you don't see the splash screen: make sure it's in the right folder) Mail me at anthony_ve@hotmail.com, if you have any more questions about this code or your program.
