Hi. In my attempts to create an email client, netbean's GUI builder has made me very unhappy... so, I decided I'd rather code it by hand... not my best idea, but whatever. Now, I'm trying to nest a Vertical JSplitPane in a Horizontal JSplitPane, and I can't see the left side of the Pane that is split down the middle. When I run the program, I only see the handle for the bar that resizes up and down... I want it to look something like this, I got it to work in the GUI builder, but I've stopped using that...:

__________
| |       |
| |       |
| +-------|
| |       |
|_|_______|

where the lines that intersect the + can be moved.

Also, the GridBagLayout is starting at the top left corner, but in the center... does anyone know how to fix that????

Here's my code:

lines 79-99 are the problem area for the JSplitPanes i believe

package JEmail;

Hello, can I get help, I am using netbeans 6 and I am now staring GUI, can i get a code for a simple game

Hi Peekay49.
This thread has already been solved. You can read through it if you would like, but posting here is going to do anything, people see that it's solved so most just ignore it. If you need help you need to start your own thread.
Also, Daniweb does not just give away code, we're here to help, not to do your work for you. You have to show that you have written your own, and we can help you if it isn't working properly.

If you need help building the GUI, look here:
http://java.sun.com/docs/books/tutorial/uiswing/learn/index.html

or here:
http://www.netbeans.org/kb/60/java/gui-functionality.html

As for the game, start with something simple: for example, when you press the mouse button, a circle appears and disappears when you press again.

All of this was explained in the rules. Please don't ask for code without showing any of your own work.
