Qt msgBox 快捷版

使用

 int iRet = msgBox(pos, tr("警告")
                       , tr("确定要删除当前选中的行吗?")
                       , tr("确定"), tr("取消"), , );
     if ( == iRet) return;  // 0:确定 1:取消

实现

 //在指定的点topLeft 显示 MessageBox
 int msgBox(const QPoint& topLeft
         , const QString &title
         , const QString &text
         , const QString &button0
         , const QString &button1
         , const int &defaultButton
         , const int &escapeButton
         , QMessageBox::Icon icon
         , QWidget *parent)
 {
     QMessageBox msg(icon, title, text, QMessageBox::NoButton, parent
                     , Qt::WindowStaysOnTopHint | Qt::Dialog | Qt::MSWindowsFixedSizeDialogHint);

     QPushButton* pBtn0 = NULL;
     QPushButton* pBtn1 = NULL;

     pBtn0 = msg.addButton(button0, QMessageBox::NoRole);   //id = 0
     if (!button1.isEmpty())
     {
         pBtn1 = msg.addButton(button1, QMessageBox::NoRole);   //id = 1
     }

     if (defaultButton == ) msg.setDefaultButton(pBtn0);
     if (!button1.isEmpty())
     {
         if (defaultButton == ) msg.setDefaultButton(pBtn1);
     }

     if (escapeButton == ) msg.setEscapeButton(pBtn0);
     if (!button1.isEmpty())
     {
         if (escapeButton == ) msg.setEscapeButton(pBtn1);
     }

     if (topLeft.x() >=  && topLeft.y() >= ) msg.move(topLeft);

     return msg.exec();  //返回用户点击的 按钮的 id
 }
