[英]Readonly JFormattedTextField
Supossing that a JFormattedTextField is enabled and contains a formatter, is there a way to make it readonly? 假设JFormattedTextField已启用并且包含格式化程序,是否有办法将其设置为只读? With a JTextField , we just need to suply a custom Document and do all the control there, but with a JFormattedTextField I suppose that things are a little more complicated as we don't want to mess with its document filter.
使用JTextField ,我们只需要提供一个自定义Document并在那里进行所有控制,但是使用JFormattedTextField,我想事情就有些复杂了,因为我们不想弄乱它的文档过滤器。 I really need this feature.
我真的需要这个功能。 So, is there a way to achieve this?
那么,有没有办法实现这一目标?
UPDATE: Just my opinion, but it seems that the JFormattedTextField is so bad designed in this sense that it leaves no easy solution to this simple problem. 更新:仅是我的观点,但是从这个意义上讲, JFormattedTextField的设计是如此糟糕,以至于没有留下简单的解决方案来解决这个简单的问题。

Can't you disable editing by setting isEditable to false? 您不能通过将isEditable设置为false来禁用编辑吗?
What about undoing every change that occurs: 撤消发生的每个更改怎么办:
JFormattedTextField formattedTextField = new JFormattedTextField("Can't touch this! :)");
formattedTextField.getDocument().addUndoableEditListener(new UndoableEditListener() {
@Override
public void undoableEditHappened(UndoableEditEvent e) {
e.getEdit().undo();
}
});
