急,急....怎样设定TextField的掩码形式?

Question

TextField passwordField = new TextField();
passwordField.setEchoChar('*');

Answer 1

不好意思,是我没表达明白,不是做成PASSWORD,而是以定义的格式显示:
比如说:2001-07-02....$300.45....
或者规定其添入的数据类型...
谁能解答,先谢喽,给分的!

给一个Date public class PaneJTextDate extends PlainDocument {
    public static String initString="####-##-##";
    private static int sep1=4, sep2=7;
    private static int month1=5,month2=6;
    private static int day1=8,day2=9;    private JTextComponent textComponent;
    private int newOffset;    public PaneJTextDate(JTextComponent tc) {
        textComponent=tc;
        try {
            insertString(0,initString,null);
        } catch (Exception ex) {}
    }    public void insertString(int offset,String s, AttributeSet attributeSet ) throws BadLocationException {
        int iTemp;
        if(s.equals(initString) ) {
            super.insertString(offset,s , attributeSet);
        } else {
            if(s.length()>1) {
                if(s.length()!=10) return;
            } else {
                try {
                    iTemp=Integer.parseInt(s);
                    if(offset==month1 || offset==month1-1)
                        if(iTemp>1) return;
                    if(offset==day1 || offset==day1-1)
                        if(iTemp>3) return;                } catch (Exception ex) {
                    return;
                }
            }            newOffset=offset;
            if(atSeparator(offset)) {
                newOffset++;
                textComponent.setCaretPosition(newOffset);
            }
            super.remove(newOffset,s.length());
            super.insertString(newOffset,s,attributeSet);
        } // end if ( !=initString)
    } // end method insertString()    public void remove(int offset,int length) throws BadLocationException {
        if(atSeparator(offset)) {
            super.remove(offset-1,1);
            super.insertString(offset-1,"0",null);
            textComponent.setCaretPosition(offset-1);
        } else {
            super.remove(offset,1);
            super.insertString(offset,"0",null);
            textComponent.setCaretPosition(offset);
        }
    }//end method remove()    private boolean atSeparator(int offset) {
        return offset==sep1 || offset==sep2;
    }} // end class PaneJTextDate()

Answer 3

JTextField不能设定掩码，
请使用JClass组件，可以轻松完成掩码的设置
