Скрыть и изменить размер панели в GridBagLayout во время выполнения ⇐ JAVA

[Anonymous]

У меня есть JPanel PanelOpslog с GridBagLayout.
На этой панели есть 2 Panel. 1 сверху и один снизу.
panelSearchOpsLog
---------------------
panelShiftTeamLogging

panelSearchOpsLog настроен на рост вниз и вправо
panelOpslog = new JPanel();
tabbedPane.addTab("Opslog", null, panelOpslog, null);
GridBagLayout gbl_panelOpslog = new GridBagLayout();
gbl_panelOpslog.columnWidths = new int[]{1155, 0};
gbl_panelOpslog.rowHeights = new int[]{212, 401, 0};
gbl_panelOpslog.columnWeights = new double[]{1.0, Double.MIN_VALUE};
gbl_panelOpslog.rowWeights = new double[]{1.0, 0.0, Double.MIN_VALUE};
panelOpslog.setLayout(gbl_panelOpslog);

....

panelShiftTeamLogging = new JPanel();
GridBagConstraints gbc_panelShiftTeamLogging = new GridBagConstraints();
gbc_panelShiftTeamLogging.fill = GridBagConstraints.BOTH;
gbc_panelShiftTeamLogging.gridx = 0;
gbc_panelShiftTeamLogging.gridy = 1;
panelOpslog.add(panelShiftTeamLogging, gbc_panelShiftTeamLogging);
panelShiftTeamLogging.setLayout(null);

....

panelSearchOpsLog = new JPanel();
panelSearchOpsLog.setFont(new Font("Tahoma", Font.PLAIN, 10));
panelSearchOpsLog.setBorder(new TitledBorder(new EtchedBorder(EtchedBorder.LOWERED, new Color(255, 255, 255), new Color(160, 160, 160)), "Search Opslog", TitledBorder.LEADING, TitledBorder.TOP, null, new Color(0, 0, 0)));
GridBagConstraints gbc_panelSearchOpsLog = new GridBagConstraints();
gbc_panelSearchOpsLog.fill = GridBagConstraints.BOTH;
gbc_panelSearchOpsLog.insets = new Insets(0, 0, 5, 0);
gbc_panelSearchOpsLog.gridx = 0;
gbc_panelSearchOpsLog.gridy = 0;
panelOpslog.add(panelSearchOpsLog, gbc_panelSearchOpsLog);
GridBagLayout gbl_panelSearchOpsLog = new GridBagLayout();
gbl_panelSearchOpsLog.columnWidths = new int[]{129, 0, 0};
gbl_panelSearchOpsLog.rowHeights = new int[]{30, 160, 0};
gbl_panelSearchOpsLog.columnWeights = new double[]{0.0, 1.0, Double.MIN_VALUE};
gbl_panelSearchOpsLog.rowWeights = new double[]{0.0, 1.0, Double.MIN_VALUE};
panelSearchOpsLog.setLayout(gbl_panelSearchOpsLog);

Теперь мне нужна возможность сделать PanelShiftTeamLogging невидимым, чтобы Панель 1 могла использовать все пространство.
Я поместил этот код в прослушиватель действий с кнопки. Он скрывает PanelShiftTeamLogging, но размер PanelSearchOpsLog не изменяется
btnHideShow.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
boolean isVisible = panelShiftTeamLogging.isVisible();
panelShiftTeamLogging.setVisible(!isVisible);

panelOpslog.revalidate();
panelOpslog.repaint();

panelOpslog.getParent().revalidate();
panelOpslog.getParent().repaint();
}
});

PS: я хочу остаться с GridBagLayout
