C# waitone-like functionality?

IknowQT

The function I want to do may not be exactly the same as waitone, but for example it repeats some action in a for loop.
The code inside the for loop repeats continuously, but I want to wait until a specific signal is received.

Is there a way to stop repeating until a specific signal is received and resume when the signal is received?

You have to process this as iteratively as a loop

No, you don't.
Implement it properly using signals/slots, then you do not need such a loop.

@IknowQT You should not have any long lasting loops when using event driven frameworks like Qt! Else signals/slots will not work!
What you can do: use a timer, in the slot connected to the timout signal you put the code you currently have in that loop. In the slot you connect to the signal you described you set a flag variable which you then check in the timout slot to decide whether you should execute the code or not.

	for (int nCnt = 1; nCnt <= m_pDataModel->rowCount(); nCnt++)
		{
			// [ 샘플을 넣으세요 Msg 출력]
			{
				wMessageBox msg(QString::fromLocal8Bit("샘플을 삽입하십시오"), this);
			}

			cGlobalParam::SendMeasureStart(ModeTypes::StandardCurve);

			if (data)
			{
				qDebug() << "data1 : " << data;
				float fa = data->ABS;
				float ft = data->Trans;
			}
			
		}
		break;

cGlobalParam::SendMeasureStart(ModeTypes::StandardCurve) is a function that tells the measurement start from tcp.

After clicking on the message, it sends a start signal and when a packet indicating that the action is over is received, it tries to process the data.
You have to process this as iteratively as a loop. And since there is time to measure, the next loop can be performed only when the measurement complete signal is received.

Can I use it as a qtimer in this case as well?

Thank you for your reply. Let's try it.
