Hi ,

I have project made in QT 4.7.
Now i see that QT 5 is released and have installed it.
I noticed that a lot of clases has changed.A lot of them now are in QtWidgets/ i changed my code in accordance with this change.
Now i have only one problem before run my code.

The error:
ui_mainwindow.h file not found

I didn't change nothing in the mainwindow.ui file neither in mainwindow.

PLEASE HELP!
