formatting text in jdialog box
提问by whitewolfpgh
I have a JOptionPane:
我有一个 JOptionPane：
JOptionPane.showMessageDialog(null, text);
The text is a sting:
文字是刺痛：
String text = "Hello world."
What I want to do is change the color of the text, specifically a single word, lets say 'Hello'. SO what I've tried is:
我想要做的是改变文本的颜色，特别是一个单词，让我们说“你好”。所以我试过的是：
String t1 = "Hello";
String t2 = "world."
Font serifFont = new Font("Serif", Font.BOLD, 12);
AttributedString as = new AttributedString(t1);
as.addAttribute(TextAttribute.FONT, serifFont);
as.addAttribute(TextAttribute.FOREGROUND, Color.red);
JOptionPane.showMessageDialog(null, as+t2);
I'm not familiar with attributedtext() and this wont work. It does this:
我不熟悉attributedtext()，这行不通。它这样做：
"java.text.AttributedString@479c479cworld"
“java.text.AttributedString@479c479cworld”
Is there a step I'm missing? Is this not the right way? Any suggestions?
有没有我遗漏的步骤？这不是正确的方法吗？有什么建议？

It should be possible to use html to solve this, ie
应该可以用html来解决这个问题，即
String t = "<html><font color=#ffffdd>Hello</font> world!";
See http://docs.oracle.com/javase/tutorial/uiswing/components/html.htmlfor more info.

You can pass a Componentto JOptionPane in the message parameter and will use that to display your message.
您可以Component在消息参数中将a 传递给 JOptionPane 并使用它来显示您的消息。
Something like a JLabelor a JPanelwith labels on it.
像 aJLabel或 a 之类的东西JPanel，上面有标签。
