java取代了JTable的组合框编辑器

Question

通过在java中扩展默认编辑器，我为我的表创建了一个自定义编辑器。代码看起来像

import java.awt.Component;
import java.text.ChoiceFormat;

import javax.swing.DefaultCellEditor;
import javax.swing.JComboBox;
import javax.swing.JTable;

import com.ushustech.nmsazzist.model.mib.MibVariableModel;


public class MibFormattedValueEditor extends DefaultCellEditor
{

private JComboBox m_comboBox;
public MibFormattedValueEditor()
{
    this(new JComboBox());
}

public MibFormattedValueEditor(JComboBox comboBox)
{
    super(comboBox);
    this.m_comboBox = comboBox;
}

@Override
public Object getCellEditorValue()
{
    return this.m_comboBox.getSelectedItem();
}

@Override
public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column)
{
    this.m_comboBox.removeAllItems();
    MibVariableModel model = (MibVariableModel) table.getModel();
    ChoiceFormat format = model.getMibVariable(row).getFormat();

    if(null != format){
        Object[] obj = format.getFormats();
        for(int i=0;i<obj.length;i++){
            this.m_comboBox.addItem(obj[i].toString());
        }

    }

    return super.getTableCellEditorComponent(table, value, isSelected, row, column);

}

}  

如果格式为空，我想显示文本字段编辑器？请帮我做这个？谢谢

我不会更换ComboBox，因为这可能会弄脏。我宁愿在format == null的情况下将其设置为可编辑，并让用户在这里输入信息。像这样：

if(null != format) {
   // ...
} else {
   this.m_comboBox.setEditable(true);
}
