JButton显示问题

Question

GUIJbutton

Answer 1

public Car()
{
System.out.println("***");
path = new GeneralPath();
path.moveTo(50, 50);
path.lineTo(200, 200);
float[] dash = new float[] { 5, 5 };

for (int i = 0; i < 6; i++) {
bs[i] = new BasicStroke(6.0f, BasicStroke.CAP_BUTT,
BasicStroke.JOIN_MITER, 10.0f, dash, i);
}
this.OpenFile=new JButton("Open File");
this.lblTime = new JLabel("Start");
        this.lblTime.setFont(new Font("Monospaced", Font.BOLD, 30));
        this.lblTime.setHorizontalAlignment(SwingConstants.CENTER);
        this.lblTime.addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent e)//鼠标点击事件
            {
                begin = true;
                lblTime.setText(timeStr(Start));
               
            }
        });
        add(lblTime);
        add(OpenFile);
      
        //setLayout(new BorderLayout());
        //add(lblTime, BorderLayout.NORTH);
        this.setLayout(null);
        lblTime.setBounds(800,20,100,30);
        OpenFile.setBounds(600,20,150,30);
timer.start();
}
但是JLabel  lbltime就没有这个情况。。

Answer 2

你是不是重写了paint等会影响窗体绘制的方法？
虚线的问题你不是自己定义了那几个BasicStroke，不就是那样的虚线吗，你应该修改了窗体线段的绘制方法吧

Answer 3

嗯，是重写了paint。。那是不是就不能同时画虚线啊。。

Answer 4

刚才把画虚线的暂时屏蔽掉了，已经解决了第二个问题！那重写paint的问题应该怎么解决呢？？

Answer 5

刚才把画虚线的暂时屏蔽掉了，已经解决了第二个问题！那重写paint的问题应该怎么解决呢？？
你把paint部分的代码发出来看看

你把paint部分的代码发出来看看public void paintComponent(Graphics g) {

//System.out.println("senderX:"+senderX);
//System.out.println("receiverX:"+receiverX);
Graphics2D g2 = (Graphics2D) g;
if (!begin) return;//鼠标点击之后begin=true
super.paintComponent(g);
g.setColor(Color.BLACK);//画边框
//g2.drawLine(300, 0, 300, 1000);
g2.drawRect(505, 105, 600, 550);


        if (Start >= MAXTIME) {
            lblTime.setText("END!!");
        }
        Start += 1;
        lblTime.setText(timeStr(Start));

Answer 7

刚才把画虚线的暂时屏蔽掉了，已经解决了第二个问题！那重写paint的问题应该怎么解决呢？？
你把paint部分的代码发出来看看
是不是不在这部分代码里面呀？我定义了一个按钮，按钮启动后开始调用repaint（）方法。。

Answer 8

没仔细看，可能你每次paint之前没有擦除原来的吧

Answer 9

已经搞定啦~我把timer放到一个按钮里面就ok了！
