Qt threads

[esanhi]

Hello,

I am developing a Qt interface for a 3D printer. When I cilck the Print button (the printer starts printing) the interface crashes. I am using this code:

@*future= QtConcurrent::run(Imprimir,filename.toUtf8().data());@

What can I use to solve it?? What types of threads can I use????

I need to use the interface while the printer is printing (it may take several minutes).

Thank you for advance.

Hi and welcome to devnet,

With only that it's difficult to tell. The code of Imprimir would be useful to understand your problem.
