Run qt example is not warning and error but nothing is displayed (exception window)

[longhoangdev]

Hello everbody,
I have a trouble with qt creator 4.14.1 when i run qt example is not warning and error but nothing is displayed (exception window white screen) ( below the image). I have already installed window 10 and installed qt creator .Example I run that is qmlchart and i use mingw 8.1 64 bit

So do i install missing file ? I guess issue belongs to graphics ( because nothing is display example color , rectangle, v.. v....) and i checked my computer is using directX 12

Could anyone please help me?

Thank you,

@longhoangdev Did you try other examples? Do those work?

@longhoangdev well, if you do not explicitly tell it to, Qml will still use OpenGL for qml rendering

IIRC, setting qputenv("QSG_RHI", "1"); should remedy that...

You can check if it helps

@J-Hilk
where can I find IIRC, setting qputenv("QSG_RHI", "1") ? I don't understand it

@longhoangdev
More information here:
https://doc.qt.io/qt-5/qtquick-visualcanvas-scenegraph-renderer.html#rendering-via-the-qt-rendering-hardware-interface

qputenv is the Qt- way (notice the q before putenv ?) of setting an environment variable
