问题描述
我有一个不寻常的问题：如何使用Swing创建命令控制台？
我想拥有的是一个用户控制台输入命令，按回车键，命令输出显示在。我不想让用户更改提示和旧输出。我在考虑像Windows CMD.EXE这样的东西。
我看了问题，但它没有回答我的问题。
BeanShell提供了一个JConsole，一个命令行输入控制台，具有以下功能：
- 一个闪烁的光标
- 命令历史记录
- 剪切/复制/粘贴，包括使用CTRL +箭头键选择
- 命令完成
- Unicode字符输入
- 彩色文本输出
- ...它们都包含在滚动窗格中。
可以从和来源可通过SVN从 svn co http://ikayzo.org/svn/beanshell

以下是在应用程序中使用BeanShell的JConsole的示例：
import java.awt.Color中;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.Reader;
import javax.swing.JFrame;
import bsh.util.GUIConsoleInterface;
import bsh.util.JConsole;

注意： JConsole返回;如果您单独按Enter键。
I have a bit of an unusual question: How can I create a "Command Console" using Swing?
What I want to have is a console where the users type in commands, press enter, and the output from the command is displayed under. I don't want to allow the user to change the "prompt" and older output. I am thinking of something like Windows CMD.EXE.
I had a look at this question, however it doesn't answer my question.
BeanShell provides a JConsole, a command line input console with the following features:
- a blinking cursor
- command history
- cut/copy/paste including selection with CTRL+arrow keys
- command completion
- Unicode character input
- coloured text output
- ...and it all comes wrapped in a scroll pane.
The BeanShell JARs are available from http://www.beanshell.org/download.html and the source is available via SVN from svn co http://ikayzo.org/svn/beanshell
For more info on JConsole see http://www.beanshell.org/manual/jconsole.html
Here is an example of using BeanShell's JConsole in your application:
import java.awt.Color;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.Reader;
import javax.swing.JFrame;
import bsh.util.GUIConsoleInterface;
import bsh.util.JConsole;
/**
* Example of using the BeanShell project's JConsole in
* your own application.
*
* JConsole is a command line input console that has support
* for command history, cut/copy/paste, a blinking cursor,
* command completion, Unicode character input, coloured text
* output and comes wrapped in a scroll pane.
*
* For more info, see http://www.beanshell.org/manual/jconsole.html

private static void inputLoop(GUIConsoleInterface console, String prompt) {
Reader input = console.getIn();
BufferedReader bufInput = new BufferedReader(input);
String newline = System.getProperty("line.separator");
console.print(prompt, Color.BLUE);
String line;
try {
while ((line = bufInput.readLine()) != null) {
console.print("You typed: " + line + newline, Color.ORANGE);
// try to sync up the console
//System.out.flush();
//System.err.flush();
//Thread.yield(); // this helps a little
if (line.equals("quit")) break;
console.print(prompt, Color.BLUE);
}
bufInput.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
NB: JConsole returns ";" if you hit Enter by itself.
