Updating 'Current Elapsed Time' in the GUI

[RBrNx277]

Hi there, I currently have a program which has two main sections, the mainWindow class which is the GUI portion of my program, and a SokoGenerator class which is running on a QThread so that the GUI can update while the Generator is running.

Id like to start a timer once a button is clicked, and then constantly update the GUI with the current elapsed time of the program, and then stop updating the timer once the Generator has finished it's execution. I tried to use the QTime Class but I was not very successful as I couldn't calculate the time difference using the following code:

QTime currentTime = QTime::currentTime();
QTime diffTime = currentTime - startTime;
QString timeString = diffTime.toString("hh : mm : ss");
ui->label_GenerationTime->setText("Current Generation Time: " + timeString);

What is the best way to update a GUI Label with the current elapsed time, and then stop updating once the Generator has finished running?

Thanks, RBrNx
