GridBagLayout Compile problems

[capp luckett]

HI:
I am having trouble getting my app to compile due to the
GridBagLayout.
The error I am getting is "Form.java:118: cannot resolve symbol
symbol : method add (javax.swing.JCheckBox,int,int,int,int)
location: class java.awt.Container
getContentPane().add(ckHourly, 0, 1, 1, bFill);"
In fact, I am getting a error everywhere I am doing a getContentPane().add.
Any clues would be appreciated.
The code, rather lengthy, is:

Compare your add method with the API they don't match. You need to investigate GridBagLayout a little more. It looks like you are trying to set your grid within the add.

Thanks.
I have been looking at the 1.3 API but still confused.
I am trying to add my labels, textfields and buttons in the
grid.

[Paul Stevens]

Here is a link the the sun tutorial on GridBagLayout.
This link is to the explanation of using the layout.
Notice that in the explanation that the constraints are set then the component is added to the container.

button = new JButton("Button 1");
c.weightx = 0.5;
c.gridx = 0;
c.gridy = 0;
gridbag.setConstraints(button, c);
contentPane.add(button);

In the above example a button is added to grid location 0, 0. There are other ways to position them as well but the grid location will get you started.

Got it.Thanks a lot.
