Hi all
I want to run a opengl program but not show any thing in main window(Qt Creator 4.3.1-Qt 5.9.0). I used to run this program in a old version Qt and run without any problem. I checked Qt +=opengl and add
LIBS += -LC:\Qt\Qt5.9.0\5.9\mingw53_32\lib -lglew32
LIBS += -lopengl32
but just show a white page.I try run other program with opengl but it had the same problem again.

Hi and welcome to devnet,
What old version of Qt is it working on ?
What version of Windows are you running ?
What's your graphic hardware ? -

Hi
Depending on how old the Qt where it used to work it,
maybe the openGL requirements have been
raised.Did you check with some other openGL application that
in fact the intel HD does work ?
