在Java中的textArea中将字体和颜色设置为字符串 [英] Set font and color to string in textArea in Java

问题描述

大家好，



我有一个关于聊天客户端服务器的练习，所以我没有很多java，

我正在为聊天私密编码。我有一些问题需要你的帮助。

1.我有一个textArea来包含聊天消息，我希望设置字体和颜色与用户名部分相同：



ga_con：你好汤姆。

老虎：嗨结婚。



2.我有一个列表朋友并将它们显示给主聊天（同一个雅虎），但我不知道哪个最佳控件可以显示它们和它们的图标。在这种情况下我们可以改变状态当朋友通过更改他们的图标登录（在线）时，朋友从离线到在线。当我双击nay朋友时，这个控件必须允许m打开私人聊天窗口。



希望尽快得到你的帮助。



P / S：请给出一些代码行



提前感谢

解决方案

< blockquote>首先，这是一项经典的家庭作业。所以我想把编码留给你。



我会定义颜色，也许可以通过JcolorChooser对话框选择。

这些颜色需要应用于文本。为了简单起见，我不会想到一个JTextArea而是一个Scrollpane，我将标签添加到。



这些标签应该是自定义的。他们会保留颜色并将一个或另一个应用于标签：

  public  类 CustomLabel扩展JLabel {
 
  private   final 颜色oColor1，oColor2; 
 
  public  CustomLabel（）{
  super （strText）; 
  //  设置颜色 
 此 .ignition（）; 
} 
 
  private   void  ignition（）{
  this  .setForeground（oColor1）; 
} 
}

解决方案

First of all, this is a classic homework task. So I would like to leave the coding to you.

I would define the colors, maybe selectable via a JcolorChooser Dialog.
These colors need to be applied to the text. To make that simpler, I would Not think of a JTextArea but of a Scrollpane, that I add Labels to.

These Labels should be custom. They would hold the colors and apply one or the other to the Label:

public class CustomLabel extend JLabel{

private final Color oColor1, oColor2;

public CustomLabel(){
  super(strText);
  // set colors
  this.ignition();
}

private void ignition(){
  this.setForeground(oColor1);
}
}
