QMessageBox中按鈕漢化|確定，取消

1.方法一：

QMessageBox mess(QMessageBox::Question, "刪除提示", "確認刪除所選組件?", NULL);
QPushButton *okButton = mess.addButton(tr("確定"), QMessageBox::AcceptRole);
QPushButton *cancelButton = mess.addButton(tr("取消"),QMessageBox::RejectRole);
mess.exec();
if ((QPushButton*)mess.clickedButton() == okButton)
{
}

2方法二：

QMessageBox::warning(this,tr("test"), tr("msg"), tr("Yes"), tr("No"), tr("Cancel"));

然後翻譯tr("Yes"), tr("No"), tr("Cancel")三個即可
