如何显示我在JFrame上的JOptionPane中输入的内容? [英] How do I display something I enter in a JOptionPane on the JFrame?

问题描述

我想要做的是当我在JOptionPane中输入某些内容时，例如APPLES.我想在JFrame中将其显示为APPLES.现在，如果我想接下来输入CATS，它将与APPLES一起出现在JFrame中.

What I want to do is when I input something in JOptionPane, say, APPLES. I want to display it as APPLES in the JFrame. Now, if I want to input CATS next, it'll appear in the JFrame together with the APPLES.

它应该像这样:APPLES CATS

It should look like this: APPLES CATS

当我输入更多内容时，它会显示并显示.我知道怎么做的唯一方法是对JLabel使用setText，但是它只显示一个单词.如何显示我输入的所有单词?

And when I input more, it just displays and displays. The only way I know how to do it is to use setText for JLabel, but it's only displaying ONE word. How do I display ALL of the words I input?

推荐答案

但是只显示一个字

but it's only displaying ONE word

希望您正在JFrame中用JOptionPane编写单词，请尝试以下操作:

Hoping that you are getting word written in JOptionPane in JFrame, try this:

jLabel.setText(jLabel.getText() + " " + strGotFromJOptionPane);

strGotFromJOptionPane是您从JOptionPane获得的文本.

Here strGotFromJOptionPane is the text you got from JOptionPane.
