我在使用JFrame时遇到问题,而在

连续运行代码.下面是我的代码：

>单击btnRun时,我调用了函数MainLoop()：

ActionListener btnRun_Click = new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

MainLoop();

}

};

> MainLoop()的实现：

void MainLoop()

{

Hopper = new CHopper(this);

System.out.println(Hopper);

btnRun.setEnabled(false);

textBox1.setText("");

Hopper.getM_cmd().ComPort = helpers.Global.ComPort;

Hopper.getM_cmd().SSPAddress = helpers.Global.SSPAddress;

Hopper.getM_cmd().Timeout = 2000;

Hopper.getM_cmd().RetryLevel = 3;

System.out.println("In MainLoop: " + Hopper);

// First connect to the validator

if (ConnectToValidator(10, 3))

{

btnHalt.setEnabled(true);

Running = true;

textBox1.append("

Poll Loop

"

+ "*********************************

");

}

// This loop won't run until the validator is connected

while (Running)

{

// poll the validator

if (!Hopper.DoPoll(textBox1))

{

// If the poll fails, try to reconnect

textBox1.append("Attempting to reconnect...

");

if (!ConnectToValidator(10, 3))

{

// If it fails after 5 attempts, exit the loop

Running = false;

}

}

// tick the timer

// timer1.start();

// update form

UpdateUI();

// setup dynamic elements of win form once

if (!bFormSetup)

{

SetupFormLayout();

bFormSetup = true;

}

}

//close com port

Hopper.getM_eSSP().CloseComPort();

btnRun.setEnabled(true);

btnHalt.setEnabled(false);

}

>在MainLoop()函数中,while循环一直运行,直到“运行为真”问题是,如果我想停止while循环,则必须将Running设置为false,这是在另一个按钮btnHalt上完成的：

ActionListener btnHalt_Click = new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

textBox1.append("Poll loop stopped

");

System.out.println("Hoper Stopped");

Running = false;

}

};

但是btnHalt没有响应,整个帧被冻结,也没有

显示文本区域中的任何日志.
