在外观更新后刷新JTable

Question

我有一个带有自定义TableCellRenderer的JTable。

public class DateCellRenderer extends DefaultTableCellRenderer {

    private static final long serialVersionUID = 58L;

    public DateCellRenderer() {
        super();
        setHorizontalAlignment(CENTER);     
        setOpaque(true);
    }
    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {         
        if (value instanceof Date) {
            String date = new SimpleDateFormat("dd-MM-yyyy").format((Date) value);
            setText(date);
        }
        return this;
    }
}

同样在我的应用程序中，我有一个下拉菜单，通过它可以更改外观和感觉。此下拉菜单位于父框架中，表格位于对话框中。打开对话框时，父框架不可访问。因此，要更改外观，我必须先关闭对话框。

现在在特定皮肤中，如果表格由某些数据填充，我从父框架更改外观并再次打开对话框，那么我添加了TableCellRenderer的列保持旧的外观。当其他列以新的外观呈现时，它不会更新。

我无法找到问题及其解决方案。任何帮助都很明显。

注意：应用程序的外观更新由以下代码段

完成

javax.swing.UIManager.setLookAndFeel(uiProperties.getThemeModel().getThemeClass());
ComponentFactory.getLibraryFrame().getRootPane().updateUI();
for (int i = 0; i < Frame.getWindows().length; i++) {
    SwingUtilities.updateComponentTreeUI(Frame.getWindows()[i]);
}
for (int i = 0; i < Frame.getFrames().length; i++) {
    SwingUtilities.updateComponentTreeUI(Frame.getFrames()[i]);
}

提前致谢。

首先选择HiFi主题：

然后我将主题更改为Fast，第二列“Released”未更新其ui：

JTable是：

public class MovieSearchResultTable extends BaseTable {

    private static final long serialVersionUID = 45L;

    public MovieSearchResultTable(TableModel tableModel) {
        super(tableModel);
        LibraryLogger.initMessage(getClass().getSimpleName());
    }

    @Override
    public void initialize() {
        setFillsViewportHeight(true);
        setAutoResizeMode(AUTO_RESIZE_OFF);
        getColumnModel().getColumn(1).setCellRenderer(new DateCellRenderer());//if I comment out this line then no problem. but without CellRenderer how could I format a Date, if I use formatted String instead of Date, then the column will not sort!!
    }

    @Override
    public boolean getScrollableTracksViewportWidth() {
        return getPreferredSize().getWidth() < getParent().getWidth();
    }
}

Answer 1

我认为不好L＆amp; F，JTable看起来......好吧，但是其他复合JComponents不是......，不确定我没有浪费时间，我离开去测试，也许是在他们的论坛或文档或BugParades中描述了一些内容，但没有提到您的问题

有非常简单的方法，你可以随时检查

1）转到Insubstantial

2）下载代码源，

3）将所有类导入IDE（2-15分钟取决于PC硬件）

4）搜索文件夹测试，有Check.java，

5）运行该操作并尝试JMenu外观中的所有内容，然后才需要为每Custom Java Swing Look and Feels

下载API

解决方案，您需要覆盖public Component prepareRenderer(TableCellRenderer renderer, int row, int column)

这是班级：

public class MovieSearchResultTable extends BaseTable {

    private static final long serialVersionUID = 45L;

    private int rolloverRowIndex = -1;

    public MovieSearchResultTable(TableModel tableModel) {
        super(tableModel);
        LibraryLogger.initMessage(getClass().getSimpleName());
    }   

    public Component prepareRenderer(TableCellRenderer renderer, int row, int column) {
        Component component = super.prepareRenderer(renderer, row, column);
        Color foreground = getForeground();
        Color background = getBackground();
        if (isRowSelected(row)) {
            foreground = getSelectionForeground();
            background = getSelectionBackground();
        }
        else if (row == rolloverRowIndex) {
            foreground = getSelectionForeground();
            background = ColorHelper.brighter(getSelectionBackground(), 40);
        }
        else if (row % 2 == 0) {
            background = ColorHelper.brighter(getParent().getBackground(), 20);
        }
        component.setForeground(foreground);
        component.setBackground(background);
        return component;
    }

    private class RolloverListener extends MouseInputAdapter {

        public void mouseExited(MouseEvent e) {
            rolloverRowIndex = -1;
            repaint();
        }

        public void mouseMoved(MouseEvent e) {
            int row = rowAtPoint(e.getPoint());
            if (row != rolloverRowIndex) {
                rolloverRowIndex = row;
                repaint();
            }
        }
    }

    @Override
    public void initialize() {
        setFillsViewportHeight(true);
        setAutoResizeMode(AUTO_RESIZE_OFF);
        TableColumnModel tableColumnModel = getColumnModel();
        for(ComponentConstant.ColumnName columnName : ComponentConstant.Column.MOVIE_SEARCH_RESULT_TABLE) {
            int order = columnName.getOrder();
            TableColumn tableColumn = tableColumnModel.getColumn(order); 
            if(order == 0) {
                continue;
            }

            tableColumn.setCellRenderer(RendererFactory.getMovieSearchResultTableCellRenderer());
        }
        RolloverListener listener = new RolloverListener();
        addMouseMotionListener(listener);
        addMouseListener(listener);
    }

    @Override
    public boolean getScrollableTracksViewportWidth() {
        return getPreferredSize().getWidth() < getParent().getWidth();
    }
}

感谢。
