How can I achieve my task??

thanks for your replies.
I applied all these methods. By using setPrefferedSize the panel becomes broad but no component appearin it.

Also by using panel within a panel i have the same output.

pack() does nothing in my case.

please any help, why swing components do not appear??

Its the full width of the window; just how broad did you want it to be?

i want to change the size of north panel according to my needs. I want to accomodate components properly. But due to smaller size of the panel some of components are not visible.

I want to resize the panel that is on the NORTH/Button1 (PAGE_START) of the Border layout.

statement.setString(2, val2);
statement.setString(3, val3);
statement.setString(4, val4);
statement.setString(5, val5);

hi

I am a beginner. I am building java application which is like a form. First the user fill the whole form and the click OK.
I want to do that as the user clicks OK all the items entered in the JTextField will save in the variables that I declared.

I have do this by ActionListener. I have to press enter every time when I entered anything in JTextField. Like this:

Name=String.format("Set_Id: %s", event.getActionCommand());
Surname=String.format("Set_Id: %s", event.getActionCommand());
DOB=String.format("Set_Id: %s", event.getActionCommand());

Please help how can I do this by using MouseListener. All the values move to variables just by clicking OK.

thanks
