Question

I have a JTable with custom TableCellRenderer.

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;
    }
}

Also in my application I have a drop down menu by which I can change the look and feel. This drop down menu is in a parent frame and the table is in a dialog. When the dialog is opened the parent frame is inaccessible. So to change the look and feel I have to close the dialog first.

Now in a particular skin if the table is populated by some data and I change the look and feel from parent frame and again open the dialog then the column, where I have added the TableCellRenderer, is keeping the old look and feel. It is not updating while the other columns render themselves in the new look and feel.

I am unable to find the problem and its solution. Any help is appreciable.

Note: The look and feel update of the application is made by the following snippet

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]);
}

Thanks in advance.

In HiFi theme chosen first:

Then I change the theme to Fast, and the second column “Released” not updated its ui:

The JTable is:

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();
    }
}

The solution, you need to override public Component prepareRenderer(TableCellRenderer renderer, int row, int column)

Here is the class:

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();
    }
}

Thanks.
