java.awt关于TextField的设置

定义了两个文本框
public static TextField TextField_user = new TextField(40);
public static TextField TextField_password = new TextField(40);
想要当点击文本框的时候，自动选定文本框内所有内容，就像这样

最好直接上代码吧

Answer 1

TextField_user.addFocusListener(new FocusListener(){
public void focusGained(FocusEvent e) {
TextField_user.selectAll();
}
public void focusLost(FocusEvent e) {
}

});
