分享SWT中的TXT文本框怎么响应回车键事件啊
请问我在界面上几个对象，文本框，下拉框，按钮，我想通过回车来从一个文本框跳到另外一个，好像Tab键一样的功能。
谢谢～～～～～～～～～～

SWT这样也行。按回车键后变为TAB
TraverseListener traverseListener = new TraverseListener() {
public void keyTraversed(TraverseEvent e) {
if (e.keyCode == 13) {
e.detail = SWT.TRAVERSE_TAB_NEXT;
e.doit = true;
}
}
};
text1.addTraverseListener(traverseListener);
text2.addTraverseListener(traverseListener);
TraverseListener traverseListener = new TraverseListener() {
public void keyTraversed(TraverseEvent e) {
if (e.keyCode == 13) {
e.detail = SWT.TRAVERSE_TAB_NEXT;
e.doit = true;
}
}
};
text1.addTraverseListener(traverseListener);
text2.addTraverseListener(traverseListener);

你看看这个简单的程序：

/**

public class TestFrame2 implements ActionListener {
public static String str ;
private static JFrame jfr = new JFrame("Frame");
JButton jbt_ok = new JButton("OK");
JButton jbt_cal = new JButton("CANCLE");
JTextField jtf = new JTextField(20);
public static JTextArea jta = new JTextArea("",20,50);
public TestFrame2(){
//add jbt_ok to JFrame
jfr.setLayout(new FlowLayout());
jbt_ok.addActionListener(this);
jfr.add(jbt_ok);
jbt_cal.addActionListener(this);
jfr.add(jbt_cal);
jtf.addKeyListener(new koLis());
jfr.add(jtf);
jfr.setSize(300,200);
jfr.setVisible(true);
}
public static void main(String[] args){
new TestFrame2();
jfr.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public void actionPerformed(ActionEvent e){
if(e.getActionCommand()=="OK"){
jtf.setText("test");
}
if(e.getActionCommand()=="CANCLE"){
jtf.setText("");
}
}
/**
* The class implement a Listener for jtf
*/
class koLis extends KeyAdapter {
public void keyPressed(KeyEvent e){
if(e.getKeyCode()==10){
jtf.setText("Enter pressed");
}
}
}
}

SWT里可以用AWT的事件监听器？

ItemStateListener接口
此接口在那些想具有处理同意form中相关组件之间的内部状态变化能力的方法中实现,接口必须实现
void itemStateChanged(Item item) 方法,当指定Item发生如下几种变化的情况:
changes the set of selected values in a ChoiceGroup; //choiceGroup的值发生变化
adjusts the value of an interactive Gauge; //调节相互度量的值(相对的值???)
enters or modifies the value in a TextField; //输入或者更改了文本框中的值
enters a new date or time in a DateField; and //输入新的数据或者事件在数据域
回车算不算呢???

就监听ActionListener, 文本中的回车事件＋按钮单击，对。建议去把ＪＦＣ的Tutorial中相关章节看一遍。

ActionLinstener 可以监听文本的回车事件，和按钮单击事件

问一下java_augur兄：
combo.addListener (SWT.DefaultSelection, new Listener ()
这句加的监听器是SelectionListener吗？SelectionListener可以像AWT里的ActionListener一样监听Text的回车事件吗？
combo.addListener (SWT.DefaultSelection, new Listener ()

也有一个方法:
public void action(Event e,Object o)
{
if(e.target ==？ )
{
if(……)
{……}
}
}
比较好用，但是个比较老的方法
public void action(Event e,Object o)
{
if(e.target ==？ )
{
if(……)
{……}
}
}

实话跟你说:

swing下这样
passwordField.addKeyListener(new KeyListener() {
public void keyReleased(KeyEvent e) {}
public void keyTyped(KeyEvent e) {}
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_ENTER) {
。。。。。
}
else if (e.getKeyCode() == KeyEvent.VK_ESCAPE) {
System.exit(0);
}
}
});
passwordField.addKeyListener(new KeyListener() {
public void keyReleased(KeyEvent e) {}
public void keyTyped(KeyEvent e) {}
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_ENTER) {
。。。。。
}
else if (e.getKeyCode() == KeyEvent.VK_ESCAPE) {
System.exit(0);
}
}
});

应该用KeyListener可以实现吧。在文本框里加一个KeyListener~~判断是不是回车事件~~
个人想法。没有真正的试过~~
