Did it display any errors or any messages in your output-box? Could you post them in that case?

Hi,

What is your operating system?

Are you using a physical machine or a virtual machine?

What is your graphics card?

Windows 7
physical machine
I no have graphics card, just on-borard video

Well, i would say the problem is that you've got no graphics-card, but i could be wrong.

JKSH

Qt requires support for OpenGL 2 or higher. If you only have an onboard graphics chip, then you probably don't have this OpenGL support.

Try using the non-OpenGL version of Qt instead: Go to http://qt-project.org/downloads and download a package that doesn't contain "OpenGL" in its name.

Thanks by all answer, i will do some tests.....all answer was of great help...

This is very common trouble with computers of little quality( in Brazil exists many )

If you guys find more answers, please inform me

Thanks....

You're welcome. I'll see what i can find but the problem is probably the non-opengl support. Just try it out without open-gl and it should work out fine. Otherwise you still can use QtQuick 1.0 which doesn't support OpenGL by itself.

This problem was corrected in Qt 5.4
