如何在JTextField中创建一个新行来输入？

问题描述

我想制作一个Swing程序，用于编写已完成内容的更新。它将所有信息写入不可编辑的 JTextField 。

I want to make a Swing program that writes updates on what you have done. It writes all the information on an uneditable JTextField.

例如：

You have changed the text to BLUE.
You have changed the text to RED.

问题在于我无法将两条线分开。

The problem is that I can't make the two lines separate.

我得到的是：

You have changed the text to BLUE. You have changed the text to RED.

我尝试的是:(这不起作用）

What I've tried is this: (This does not work)

TF_BetInfo.setText(TF_BetInfo.getText() + "\nYou have changed the text to BLUE.");
TF_BetInfo.setText(TF_BetInfo.getText() + "\nYou have changed the text to RED.");

推荐答案

你不能有多行使用JTextField，你可以使用JTextArea来实现这个目的，代码也没有太大的不同，你仍然可以使用相同的代码，或者你可以

you can't have multiple lines with JTextField , you can use JTextArea for that purpose , and the code wouldn't be much different too , you can still use the same code or you can just

TF_BetInfo.append("\nyou have ...... ");

其中TF_Betinfo是JTextArea而不是JTextField。

where TF_Betinfo is a JTextArea rather than a JTextField .
