Solved QML window is always empty
-
@bronstein87 - sorry, silly question, re: "what's the problem?", you had already stated as much.
I'm using Windows 7 Ultimate x64 with QtCreator 4.11.1 (MSVC 2017, 32bit) and your code works when all backend related stuff is removed.
Could it be a Windows10 problem I wonder?, I don't know what else to say, sorry.
-
@bronstein87 - I suggest scrapping the current project and starting again. looking at your screenshot, I see remains of 'backend' files, perhaps this is causing problems?, admittedly, this is all guess work on my behalf.
For what it is worth, here is a screenshot of my set up running your code; -
@Markkyboy no, i tried many different projects and configurations of current project, result is the same.
I think something is missing in the system, maybe some libraries or paths are missing. or some wrong settings in qt itself -
@bronstein87 Do you see any warning in the console when running your app?
-
@jsulm Hi. I made clean and rebuilt project. And how you can see there is no any warnings or unusual messages...
-
@bronstein87 might be a driver / open gl issue
what os do you use and what graphic-card and are those drivers up to date?
-
@J-Hilk Hi. I also thought about that, but drivers up to date (i have just checked).
OS - win10 x64, graphic-card - GeForce RTX 2060 SUPER. -
@J-Hilk I added this attribute and now everything works
QCoreApplication::setAttribute(Qt::AA_UseSoftwareOpenGL );
But it seems to me that usage of software opengl is not a good idea in terms of performance. Do you have any thoughts about how to force it to work with Qt::AA_UseDesktopOpenGL ?

@bronstein87 Are you working per remote session (TeamViewer) or directly on PC? I've got troubles with QML/OpenGL and TeamViewer and often only got an empty view.
If you are using TeamViewer, take at look at this thread: https://community.teamviewer.com/t5/General-Questions/Some-applications-does-not-show-content-white-window-Windows-10/td-p/10718

@KroMignon Yes, i'm working per remote session. Thank you, this seems to be the reason, i'll check tomorrow.
-
@KroMignon You was right. Thank you.

@bronstein87 Your welcome
