【问题描述】:
我创建了一个表格,其中每行的一个单元格中都会显示一个组合框。我分别使用以下两个类作为单元格编辑器和单元格渲染器。以某种方式显示表格时,单击单元格中的每个组合框都不会打开。谁能给我一个提示?提前致谢
public class CellEditor extends DefaultCellEditor{
private static final long serialVersionUID = 1L;
public CellEditor(String[] items) {
super(new JComboBox(items));
}
}
public class ComboBoxRenderer extends JComboBox implements TableCellRenderer {
/****/
private static final long serialVersionUID = 1L;
public ComboBoxRenderer(String[] items) {
super(items);
}
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
if (isSelected) {
this.setForeground(table.getSelectionForeground());
super.setBackground(table.getSelectionBackground());
} else {
this.setForeground(table.getForeground());
this.setBackground(table.getBackground());
}
this.setSelectedItem(value);// Select the current value
return this;
}
}

请发SSCCE!

为什么要扩展 DefaultCellEditor?没有必要这样做。
