我通过在java中扩展默认编辑器为我的表创建了自定义编辑器。代码看起来像替换JTable的组合框编辑器
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);
}
}
我想显示一个文本字段编辑器,如果格式为空?请帮我做这个?谢谢。
是有真正的原因BUILT_IN支持或JComboBox的每一个(或多个)的改变可以已经得到不同的ComboBoxModel :-) – mKorbel
