java - 使用 JTextfield 文本重复搜索 JTable

Question

以下代码将从文本字段中获取文本并在 JTable 中搜索它。它仅显示文本的第一次出现。我也需要连续发生。所以，请指导我如何实现这一目标。提前致谢。

private void search8()
{
    String target8 = sear8.getText();
    for(int row = 0; row < table8.getRowCount(); row++)
        for(int col = 0; col < table8.getColumnCount(); col++)
        {
            String next8 = (String)table8.getValueAt(row, col);
            if(next8.equals(target8))
            {
                showSearchResults(row, col);
                return;
            }
        }
}

更新:

private void showSearchResults(int row, int col)
{
    CustomRenderer renderer = (CustomRenderer)table8.getCellRenderer(row, col);
    renderer.setTargetCell(row, col);
    Rectangle r8 = table8.getCellRect(row, col, false);
    table8.scrollRectToVisible(r8);
    table8.repaint();
}

class CustomRenderer implements TableCellRenderer
{
    public CustomRenderer()
    {
       label = new JLabel();
       label.setHorizontalAlignment(JLabel.CENTER);
       label.setOpaque(true);
       targetRow = -1;
       targetCol = -1;
    }

    public Component getTableCellRendererComponent(JTable table,
    Object value,boolean isSelected,boolean hasFocus,int row, int column)
    {
       if(isSelected)
       {
           label.setBackground(table.getSelectionBackground());
           label.setForeground(table.getSelectionForeground());
       }
       else
       {
           label.setBackground(table.getBackground());
           label.setForeground(table.getForeground());
       }
       if(row == targetRow && column == targetCol)
       {
           label.setBackground(new Color(176,196,222));
           //label.setBorder(BorderFactory.createLineBorder(Color.red));
           label.setFont(table.getFont().deriveFont(Font.BOLD));
       }
       else
       {
           label.setBorder(null);
           label.setFont(table.getFont());
       }
       label.setText((String)value);
       return label;
    }

    public void setTargetCell(int row, int col)
    {
       targetRow = row;
       targetCol = col;
    }
}

找到 target8 的第一个匹配项后，您会立即返回。

最好建立一个匹配字符串列表并传递给您的方法 showSearchResults。
