如题。。。

我是个新手  用QT creator环境

代码如下
#include <QtGui/QtGui>
#include "main.h"

    CLoginDlg::CLoginDlg(QWidget *parent)
     :  QDialog(parent)
    {
        QLabel *usrLabel = new QLabel(tr("用户名:"));
        QLabel *pwdLabel = new QLabel(tr("密码:"));
        usrLineEdit = new QLineEdit;
        pwdLineEdit = new QLineEdit;
        pwdLineEdit->setEchoMode(QLineEdit::Password);

        QGridLayout* gridLayout = new QGridLayout;
        gridLayout->addWidget(usrLabel, 0, 0, 1,1);
        gridLayout->addWidget(usrLineEdit, 0, 1, 1, 3);
        gridLayout->addWidget(pwdLabel, 1, 0, 1, 1);
        gridLayout->addWidget(pwdLineEdit, 1, 1, 1, 3);

        QPushButton* okBtn = new QPushButton(tr("确定"));
        QPushButton* cancelBtn = new QPushButton(tr("取消"));
        QHBoxLayout* btnLayout = new QHBoxLayout;
        btnLayout->setSpacing(60);
        btnLayout->addWidget(okBtn);
        btnLayout->addWidget(cancelBtn);

        QVBoxLayout* dlgLayout = new QVBoxLayout;
        dlgLayout->setMargin(40);
        dlgLayout->addLayout(gridLayout);
        dlgLayout->addStretch(40);
        dlgLayout->addLayout(btnLayout);
        setLayout(dlgLayout);

        connect(okBtn,SIGNAL(Clicked()),this,SLOT(accept()));
        connect(cancelBtn,SIGNAL(clicked()),this,SLOT(reject()));

        setWindowTitle(tr("登录"));
        resize(300,200);
    }

        //验证登陆有效性
        void CLoginDlg::accept()
        {
             if(usrLineEdit->text().trimmed() == tr("lcf")
                && pwdLineEdit->text() == tr("lcf"))
             {
                 QDialog::accept();
             }

             else
             {
                 QMessageBox::warning(this,
                     tr("警告"),
                     tr("用户或密码错误"),
                     QMessageBox::Yes );
                 usrLineEdit->setFocus();
             }
         }

有知道怎么改的大哥，小弟先在这里感谢了
