JCheckBox wont receive initial focus in JTable under 1.6
If I have a JCheckBox in a JTable, clicking the checkbox has no effect unless the table already has focus. This is new to 1.6 I believe.
The code example below should illustrate the problem. With focus on the JTextField at the top, try to click a checkbox in the table. It won't take respond. If you click another field in the table first, the checkbox will then begin responding. Two strange things I've noticed with it are.
1) removing the call the table.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE); makes it work correctly. Of course then it won't give up focus correctly.
2) My example has the JTable within a JInternalFrame. If the table is just in a JFrame, the problem disappears. You can commment/uncomment these two lines to see the difference:
initInteralFrame(panel);
//initNoInteralFrame(panel);
I'm very surprised nobody else has noticed this, but I didn't see any postings or bugs on it. Can anyone see something I am doing wrong or find a workaround?
I submitted this bug a while back which is probably related, but this case with the checkbox is a bit less obscure:
