如何关闭当前的JFrame而不是两者？

Question

我很难搞清楚为什么它同时关闭主要和当前的JFrame。我以粗体突出显示的部分是我遇到麻烦的地方。当我在主框架中并单击事件按钮然后退出它也退出主框架

 public void mouseClicked(MouseEvent e) {

            if (e.getSource() == m_btnAddRemoveFriend) {
                openAddRemoveGUI();
                //If the log out button is pressed, open Login
            } else if (e.getSource() == m_btnLogOut) {
                logOut();
            } else if (e.getSource() == m_contactsList) {
                openCommHist();
            } else if (e.getSource() == m_groupConversationsList) {
                openMultiRepHist();
            } else if (e.getSource() == m_btnSendMessage) {
                openSendMessageGUI();
            } else if (e.getSource() == m_friendRequestsList) {
                openFriendRequestGUI();
            } else if (e.getSource() == m_btnCollaborativeDrawingEnvironment) {
               openDrawingEnvGUI();
            } else if (e.getSource() == m_btnAccountSettings) {
                 openAccountSettingsGUI();
            **} else if (e.getSource() == m_btnProductTable) {
            new ProductTable().setVisible(true);
                Skypertawe.saveApplicationState();
            }**
