The test window contains a tabbedPane with 4 tabs.
|
|
|
|
Tab #0 without any tabComponent, just a title.
|
|
Tab #1 with a JLabel and a little JButton wrapped into JPanel
|
|
Tab #2 with a JButton (Delete #1) as a tabComponent
|
|
Tab #3 with a JTextField as a tabComponent
|
|
|
|
Check that tabbedPane and all tabComponents are shown properly
|
|
for different tabLayout and tabPlacement policies,
|
|
(you can change them with help of settings in the right panel),
|
|
and for different looks and feels (you can change L&F by using the L&F menu)
|
|
|
|
Remove tab #1 by clicking the Button labeled Delete #1 and then re-insert it
|
|
by clicking "Insert #1". Check that it works - ie Delete #1 is restored.
|
|
|
|
If everything displays and behaves as described, the test PASSES, otherwise it FAILS.
