How to force update Render Window?

[trouble3524]

Dear All:

When the Unigine Render Window lost her window focus,Unigine can't update the engine system.

But I want Unigine always update,swap,render the window also lost her focus.

Other wise ,when I drop grag a other window on Unigine Window,the Unigine Window became a big cat face..

So,how to force update it?

Forget my poor English,thank you.

call engine.app.setUpdate(1)from world/system init() function

Thank you,but I try C++ source code:

engine.app->setUpdate(1);

It's did not work.

By the way,this Unigine Render Window in a Qt QWidget.

I set a QTimer,It is done now.

Thank you very much.
