Gridbag layout

I have butons, combo boxes, etc, that I want to put in 3X3 row and column.
I used gridbag layout and they distributed themselves sparsely, and the two columns on the right and on the left are uncomfortable close to the panel boarder. I want to put some space between the 1st and the 3rd row and the edge of the panel.
In other words, I want to put them closer to the 2nd row in the center. I tested weightx property, but did not get it as per my wish.

If you have any tips, please let me know. Thank you.

I am sorry - I should have taken time to read before posting.

I want to put buttons, combo boxes, etc, in 3X3 row and column, at the center of a panel but still with some distance from the middle row/column item, with some space around the outermost items.

I used gridbaglayout and the buttons, etc. distributed themselves sparsely; the two columns on the right and on the left are uncomfortably close to the panel border. I want to put some space between the 1st and the 3rd column and the edge of the panel.
In other words, I want to put them closer to the 2nd column in the center. I tried weightx property, but did not get it as per my wish.

use an inset (it is something like padding)

constraints.insets = new Insets(10, 50, 10, 50);
