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"), 1, 1);
    if (1 == 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 == 0) msg.setDefaultButton(pBtn0);
    if (!button1.isEmpty())
    {
        if (defaultButton == 1) msg.setDefaultButton(pBtn1);
    }

    if (escapeButton == 0) msg.setEscapeButton(pBtn0);
    if (!button1.isEmpty())
    {
        if (escapeButton == 1) msg.setEscapeButton(pBtn1);
    }

    if (topLeft.x() >= 0 && topLeft.y() >= 0) msg.move(topLeft);

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