这是一个ColorEditor,和 可是在我的表里面用来渲染单元格时发现内存上涨很大，并且渲染另一个单元格时上一次的实例没有被回收，请大虾们帮忙看一下。谢谢！
public class ColorEditor extends AbstractCellEditor

button = new JButton();
button.setActionCommand(EDIT);
button.addActionListener(this);
button.setBorderPainted(false);
//Set up the dialog that the button brings up.
colorChooser = new JColorChooser();
dialog = JColorChooser.createDialog(button,
"Pick a Color",
true, //modal
colorChooser,
this, //OK button handler
null); //no CANCEL button handler

}

if (EDIT.equals(e.getActionCommand())) {
//The user has clicked the cell, so
//bring up the dialog.
button.setBackground(currentColor);
colorChooser.setColor(currentColor);

//Make the renderer reappear.

给出你的用例

[yiqiangyang]

public void setColorEditor(JTable table,TableColumn columnClass){
TableCellEditor cellEditor = new ColorEditor();
columnClass.setCellEditor(cellEditor);
ColorRenderer renderer = new ColorRenderer(true);
columnClass.setCellRenderer(renderer);
}
这个是我调用的函数，供大家参考。

顶！！！！！！！！！！！！！！！！！！！！！

[cyicecream]

给一个能运行，用的上这个东西的例子，我没有那么多时间看啊。
我得从例子上面直接找你的问题所在，好调试

[御南]

就是啊，什么包都没导入，运行不起，来个完整的程序
