Question

http://forum.java.sun.com/thread.jsp?forum=57&thread=382447&tstart=75&trange=15
above is a link to my source code,
I having difficulties of structuring code when it get large.
The programs should work from 1.3 to 1.4 at least.
Now the problem is, when doing all these stuff in the code, it works what
I expected.
But when i seperate them into several classes, and extending JPanel,
strange things happen, I do not need to implement listener anymore.
And Gridbaglayout stuff cannot resize. At least I do not know how to.
thankyou for help

Answer 1

sorry, i do not know the meaning of 'format code'.(no offense)
As I have copy the stuff from a java enviroment call drjava, so i thought
they should be format, and I have test it by pharsing the stuff from the forum back to drjava and window text editor, they both work.
My code problem was
1. Have a class call KineWorld, can compile and work when all code inside.
2.When I seperate the code into 5 more classes, Create(4 different name) and a class call Film which extend serializable.
3.The four classes Create... was to create four panel which, put into cardlayout in KineWorld.
4.(problems)All four panel now extend JPanel and don't need implement listeners.
Plus all panel now cannot resize(It like it was on another rigid panel).
The source code actually was not expected to read all through, they are far too long, I expect them to be compiled and give a general idea to the helper of what i am doing.
The only code to be examined should be where the class extend JPanel, and the main class KineWorld where the four created panel added.
