C++ QDialogButtonBox::buttonRole方法代码示例

/*!
    Opens an confirmation message box with the specified \a title, \a text and \a confirmation.
    The standard \a buttons are added to the message box. \a defaultButton specifies 
    the button used when Enter is pressed. \a defaultButton must refer to a button that
    was given in \a buttons. If \a defaultButton is QMessageBox::NoButton, QMessageBox
    chooses a suitable default automatically.

    Returns the identity of the standard button that was clicked.
    If Esc was pressed instead, the escape button is returned.

    If \a parent is \c 0, the message box is an application modal dialog box.
    If \a parent is a widget, the message box is window modal relative to \a parent.
