help with java swt :)

[shay2]

I wrote Gui code in java, using the lib of swt.

1. How can I insert user value to my variable?
For example, user inset his age, and I want to restore this data. How can I do it?

2. How can I organize the groups to be one under the other?

3. When I execute the program the window is very small and I don’t see the buttons, how can I change it?

4. How the button of "about" can be in the left corner?

5. I have "exit" function how I can connect it to the X button on the up-right corner of the window?


this is my code..
