我有一个控制所有应用程序的主类,包括显示所有面板。显示主应用程序面板的方法是:
private void displayMainApplicationPanel() {
String[] columnNames = { "Media ID", "Title", "Pricipal Actors", "Type", "Duration", "Launch Date", "Price",
"Status" };
ResultSet resultSet = databaseLogicController.showMediaInfo();
String[][] data = parseMediaResultSet(resultSet, 8);
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
graphicController.showMainApplicationPanel(data, columnNames);
addMainApplicationPanelSearchButtonActionListener();
addMainApplicationPanelSearchTextFieldKeyListener();
addMainApplicationPanelShowMyIdButtonActionListener();
addMainApplicationPanelBorrowMediaButtonActionListener();
addMainApplicationPanelMakeInternetRezervationButtonActionListener();
addMainApplicationPanelShowVHSInformationButtonActionListener();
addMainApplicationPanelShowDVDInformationButtonActionListener();
addMainApplicationPanelShowInternetRezervationsActionListener();
addMainApplicationPanelShowClientsInformationButtonActionListener();
addMainApplicationPanelInsertClientButtonActionListener();
addMainApplicationPanelInsertMovieButtonActionListener();
addMainApplicationPanelInsertVHSButtonActionListener();
addMainApplicationPanelInsertDVDButtonActionListener();
}
});
}
在该主面板上,我有一个显示所有当前媒体的表格。我希望能够通过搜索功能更新该表。
搜索按钮动作侦听器的代码是:
private void addMainApplicationPanelSearchButtonActionListener() {
graphicController.getMainApplicationPanel().addSearchButtonActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
String[] columnNames = { "Media ID", "Title", "Pricipal Actors", "Type", "Duration", "Launch Date", "Price",
"Status" };
String title = graphicController.getMainApplicationPanel().getSearchTextField().getText();
ResultSet resultSet = databaseLogicController.showParticularMediaInfo(title);
String[][] data = parseMediaResultSet(resultSet, 8);
graphicController.getMainApplicationPanel().setMediaTable(new JTable(data, columnNames));
graphicController.getMainApplicationPanel().repaint();
graphicController.getMainApplicationPanel().revalidate();
graphicController.getMainFrame().repaint();
graphicController.getMainFrame().revalidate();
}
});
}
现在,我根据搜索条件在动作侦听器中创建一个新表,并在主应用程序面板中设置它,然后调用主框架和主面板上的重绘和重新验证。为什么不显示新表?

我不建议你使用这一行
graphicController.getMainApplicationPanel().setMediaTable(new JTable(data, columnNames));
您可以更好地获取该表格((DefaultTableModel)myTable.getModel()).setRowCount(0);
和((DefaultTableModel)myTable.getModel()).addRow(new Object[]{data1, data2, ...});

现在,我根据搜索条件
在动作侦听器中创建一个新表
不要创建新表。最简单的方法是使用新的TableModel更新现有表:
table.setModel(...);
