Refresh the mainwindow / functions called in the main loop

[valerianst]

May be this could help, if you call this method before doing computation, it should refresh you GUI.
http://doc.qt.io/qt-4.8/qcoreapplication.html#processEvents

Uhm ok, thank you. It's a method of the QCoreApplication so I assume I should pass a reference to it in my mainwindow, right?

Be advised that blocking the event processing of the UI thread is usually not a very good idea, since you program will stop responding to any kinds of events.
No user interaction, no redrawing, no timers, no sockets, etc.

I appreciate your suggestions and yes, maybe it would be better to process all this data in a thread but I don't need the GUI when doing the computation (they just load stuff).

For all the real computation I am using threads indeed.


Thank you again
