hi and welcome
Did you try one of the examples ?
If you click on Welcome and then Examples, and then type opengl in the search box, there should be some
samples. Like "Boxes". Please See if those works.

I try to build "Boxes"!

But error occred
":-1: error: This example requires Qt to be configured with -opengl desktop"

.. :(

@Mue22
Hi how did you get Qt in win 8 ?
Seems that you somehow did not get the opengl version.

Thank you!!:)

Um, Qt version is 5.5 Community V, In Qt homepage.

Did I download the wrong version? :(

@Mue22
Hi for 5.5 it should be dynamic so it should be included.. by default,
so im not sure what is going on.

Hi,

https://www.qt.io/download-open-source/#section-2

in above page,

Qt 5.5.0 for Windows 64-bit (VS 2013, 650 MB) (info) <<< downloaded this. and install include all option (all check-box true).

Thanks!!!!!:)

In that case, do you have VS2013 installed on your computer ?

FYI - I found the same thing:

Qt 5.5 commercial, MSVS2010 : Try and compile "boxes" demo and get a ton of OpenGL errors (e.g. "unresolved symbol __imp_glEnable"). The other OpenGL demos that use the newer modules work OK, but not the original stuff.

When using Qt 5.2 MSVC2010 32bit OpenGL commercial "boxes" compiles fine.

I don't see any option for an "OpenGL" version of Qt 5.5 for Windows.
Any suggestions?

So the solution to this is to add the following line to the .pro file:

win32 {
   LIBS += -lopengl32
}

That solves all of the unresolved symbol errors with Qt 5.5.
