使用JavaFX编写了一个进制小助手

效果如下：

动图效果：

 

 

 编写耗时：一个半小时。

一共有7个类，代码大概300-400行左右。

 部分代码：

public class Main extends Application
{
	public static void main(String[] args) throws Exception
	{		
		Application.launch(args);
	}
	
	@Override
	public void start(Stage primaryStage) throws Exception 
	{
		Pane pane = new Pane();
		
		Value value = new Value();
		value.pane = pane;
		
		value.decimal = new Decimal(value);
		value.decimal.show();
		
		value.hex = new Hex(value);
		value.hex.show();
		
		value.displayResult = new DisplayResult(value);
		value.displayResult.show();
		
		CopyResult copyResult = new CopyResult(value);
		copyResult.show();
		
		HexSep hexSep = new HexSep(value);
		hexSep.show();
		
		// 背景颜色
		pane.setBackground(new Background(new BackgroundFill(Color.rgb(200, 200, 200), null, null)));
		
		// ---------------------------窗口----------------------------
		Scene scene = new Scene(pane, 350, 400);
		primaryStage.setTitle("进制小助手");
		primaryStage.setScene(scene);
		primaryStage.show();
		
		// 右上角点击关闭时, 结束子线程
		primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() 
		{
		    public void handle(WindowEvent event) 
		    {
		        System.exit(0);
		    }
		});
		
		// 两次ESC退出程序
		primaryStage.addEventHandler(KeyEvent.KEY_PRESSED, new EventHandler<KeyEvent>() 
		{
			int count = 0;
			
			@Override
			public void handle(KeyEvent event)
			{
				if (event.getCode() == KeyCode.ESCAPE)
				{
					++count;
					if (count == 2)

			}
		});
		
		primaryStage.setResizable(false);
		// -----------------------------------------------------------
