Question

I’m actually having no problem when dealing with the JScrollPane with JTextArea…
But here… I have a JPanel. And I wanted to use Scroll on it.

Take a look on my JPanel here Image Preview.
I wonder how to do it in netbeans. I think I should do a bit of customized coding.
So, I tried to do like this;

1) Right Click on jPanel2, Customize Code.
2) Using This modified code;

Initialization Code:

jPanel2 = new javax.swing.JPanel();
scrb = new javax.swing.JScrollPane(jPanel2);
// Code of sub-components - not shown here

// Layout setup code - not shown here
scrb.setPreferredSize(jPanel2.getPreferredSize());
jPanel1.add(jPanel2, "card2");

Variable Declaration Code:

private javax.swing.JPanel jPanel2;
private javax.swing.JScrollPane scrb;

Then re-run my Project again….
but,… sigh. THe Scroll didn’t came up into the running app.

Is there anything I forget over here?

I tried to manipulate the Size of the jPanel2, but hence not work….
The Scroll didn’t appeared.

The problem is in this line:

jPanel1.add(jPanel2, "card2");

Instead of this write this:

jPanel1.add(scrb, "card2");

What you are doing is adding jPnael2 to a scrollpant but then instead of adding that scrollpane to jPanel1 you add jPanel2 to jPanel1 so scrollPane doesn’t even come to picture.
