flutter 一个container里面放置两个TextField用什么包裹？
- 如何才能将txtfiled放入1个mc
- java 前一窗口里textfield的数值相加在第二窗口的textfield中显示
- 用Java编译出，两个文本框和一个确定按钮。
- 关于JAVA。要求有一个文本框textfield和一个文本域textarea，并设置监视器。用getText（）方法获取文本框t
如何才能将txtfiled放入1个mc
[ol][*]createEmptyMovieClip(\"container1\",1);[*]container1._x = 100;[*]container1._y = 100;[*]container1.createTextField(\"my_txt0\",2,0,0,100,20);//注意[*]container1.my_txt0.text = \"wo kao\";[/ol]

用Java编译出，两个文本框和一个确定按钮。
楼上的说的正是，很多错误，改了一下，可以运行，但不知道是不是你要的效果
import java.awt.*;
import javax.swing.*;
public class Main extends JFrame {
JTextField textField1,textField2;
JButton button;
public Main(){
super("文本框和确定示例");
Container container=getContentPane();
container.setLayout(new FlowLayout());
textField1=new JTextField("文本框" ,10);
textField2=new JTextField("文本框" ,10);
button=new JButton("确定");
container.add(textField2);
container.add(textField1);
container.add(button);
setSize(200,100) ;
setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
Main thisClass = new Main();
thisClass.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
thisClass.setVisible(true);
}
});
}
}
关于JAVA。要求有一个文本框textfield和一个文本域textarea，并设置监视器。用getText（）方法获取文本框t
这个是很简单的事件触发机制的例子，稍等，我弄给你！！
你需要的是awt的做的？还是用swing做的？
下面是awt的
import java.awt.*;
import java.awt.event.*;
public class Demo implements ActionListener
{
TextField txtf;
TextArea txta;
public Demo()
{
Frame f = new Frame("实例");
f.setSize(500,300);
txtf = new TextField(10);
txta = new TextArea(10,8);
f.add(txtf,BorderLayout.NORTH);
f.add(txta,BorderLayout.CENTER);
txtf.addActionListener(this);
f.setVisible(true);
}
public static void main(String args[])
{
new Demo();
}
public void actionPerformed(ActionEvent e)
{
txta.append(txtf.getText());
}
}
