automatically enlarging the components problem

actually i was asking whether my bolded lines should be placed or not.

i was also asking how my internal components will behave as my JFrame behaves....i was using GridBagLayout....in this all my Panel components are coming into CENTER of my Frame. my internal Panel is not behaving as my JFame....how all my internal frame will get elarged automatically..................... plz help me....i am totally cofused with this concept......

To expand on why I am asking for this example: Your code is big and contains a lot of junk that is not related to your problem.You are the best person to pair down your code to the core issue. Otherwise you are wasting the time of everyone here who has to do that when they look at your code.

Also, many times when you create this example you will notice that the problem goes away. That is because when you cut your program down from 400 to 20 lines of code, you cut out the problem. When this happens add, piece by piece till it breaks again. When it does that last piece is the culprit.

If you don't post an example like such, someone still might help you. Both others including myself will ignore your post until you put forth some effort in creating the example.

Ok. I am not sure what you want this panel to do but some suggestions:

You are specifying overrides to the columnwidths and row widths. I am not sure you are using gridBagLayout correct, or at least in the way you want;

I suggest you read over this: http://java.sun.com/docs/books/tutorial/uiswing/layout/gridbag.html

Also, always thing about the layout that this panel is in and its parents.
