我将数组绑定到JComboBox
,如下所示:
String[] arr={"ab","cd","ef"};
final JComboBox lstA = new JComboBox(arr);
但我希望动态绑定数组JComboBox
如下:
final JComboBox lstA = new JComboBox();
void bind()
{
String[] arr={"ab","cd","ef"};
// bind arr to lstA
}
怎么做?

一个奇怪的解决方法(我的:)),可能对你有用
final JComboBox lstA = new JComboBox();
String[] arr={"ab","cd","ef"};
lstA.setModel(new JComboBox(arr).getModel());

使用动态ComboBoxModel
构建您的JComboBoxJComboBox(ComboBoxModel<E> aModel)
喜欢http://docs.oracle.com/javase/7/docs/api/javax/swing/DefaultComboBoxModel.html
m=new DefaultComboBoxModel();
j=JComboBox(m);
然后您可以添加和删除元素:
m.addElement("ab")
m.addElement("cd")
或者,如果您只需要将数组放在combox中:
new JComboBox(new Sring[]{"ab","cd","ef"})

final JComboBox lstA = new JComboBox();
void bind()
{
String[] arr={"ab","cd","ef"};
// bind arr to lstA
lstA.setModel(new DefaultComboBoxModel<String>(arr));
}
