Qml contents doesn't appear under Windows
-
Hello,
QML contents doesn't appear under Windows for a fresh project, that was generated by QtCreator.
Here is what I did :
- l have generated a project using QtCreator => New project... => Application (Qt Quick) => Qt Quick Application - Scroll => using CMake as the build system
- Using QtCreator I have built the app in Release build configuration.
- I have moved the built *.exe to a freshly created, empty folder.
- I called
C:/Qt/5.12.2/msvc2017_64/bin/windeployqt.exe QtCreatorScrollProject.exe --release --qmldir=c:\Users\<myUserName>\Documents\QtCreatorScrollProject
to deploy the Qt dependencies next to the project.
When I run this build on my development machine, it works fine :
When I try to run the exact same app on a fresh virtual machine, the window appears, but the QML contents inside of the window are not visible ( == the scrollable list doesn't appear ) :
I guessed that it is a deployment issue, so I tried to follow this guide : https://wiki.qt.io/Deploy_an_Application_on_Windows . I followed these steps :
"
Copy the following into C:\Deployment
The release version of MyApp.exe
All the .dll files from C:\Qt\5.2.1\mingw48_32\bin
All the folders from C:\Qt\5.2.1\mingw48_32\plugins
(If you used QML) All the folders from C:\Qt\5.2.1\mingw48_32\qml
"
which I actually had to translate to these steps for myself :
"
Copy the following into C:\Deployment
The release version of QtCreatorScrollProject.exe
All the .dll files from C:\Qt\5.12.2\msvc2017_64\bin
All the folders from C:\Qt\5.12.2\msvc2017_64\plugins
(If you used QML) All the folders from C:\Qt\5.12.2\msvc2017_64\qml
"
But even after having done this, the app doesn't show the QML contents.What could I do to fix this issue?
Thank you for your help in advance!

OK : I got the fix : it is a rendering issue.
When I force rendering via ANGLE, it works : Options for forcing rendering via ANGLE :
1.: setting theQT_OPENGLenvironment variable toangle. (I only tested this solution, and it works well.)
2.: compile Qt withconfigure ... -angle.
3.: callQCoreApplication::setAttribute(Qt::AA_UseOpenGLES);before creating theQApplicationobject .There is still an interesting thing : based on Qt's documentation, Qt libraries are compiled with
-opengl dynamicwhich means that Qt should fallback to using the ANGLE renderer by itself (without me having to forcefully ask it to do that).
Ref.: https://doc.qt.io/qt-5/windows-requirements.html#graphics-drivers
Ref2.: https://doc.qt.io/qt-5/configure-options.html#opengl-options-for-windowsSo it seems like that this fallback mechanism is broken.
( A bit more info about the different renderers : https://wiki.qt.io/Qt_5_on_Windows_ANGLE_and_OpenGL )

@just_a_developer do you have your qml files inside your
qrcresources ? Or do you load them from the filesystem -
@J-Hilk :
QtCreator generates a project which has QML in qrc resources :

@J-Hilk :

your argument for windeployqt seems to be wrong
you have
--qmldir=c:\Users<myUserName>\Documents\QtCreatorScrollProjectand it probably should be
--qmldir c:\Users<myUserName>\Documents\QtCreatorScrollProject -
@just_a_developer do you have your qml files inside your

I just tried with :
--qmldir c:\Users<myUserName>\Documents\QtCreatorScrollProject, and I got the same results : QML contents still don't appear.
Just for the reference : here is the full project :
https://github.com/szigetics/QtCreatorScrollProject
( This is actually exactly what QtCreator gives you when you create a new project. ) -
I wonder if this is a case of needing "the common hack" of passing all of the Qt framework
qmlas theqmldir.My build script (yes, I run bash on windows) does it like so:
windeployqt "${FLAVOR}" --qmldir "${WINALLQML}" app.exeWhere WINALLQML is something like
C:/my_third_party_sources/Qt_desktop/5.15.0/msvc2019_64/qml -
You'll really want to see what the STDOUT/STDERR (console output) is printing when you launch the
exe.There should definitely be a warning or an error printed that would clarify what exactly is going wrong.
I don't often work on windows, so my knowledge of how exactly to see all the output is "spotty", but if you aren't seeing any output then I think you need to add
CONFIG+=CONSOLE, as in...qmake.exe CONFIG+=CONSOLE path/to/project -

Thank you for your reply.I have added
--qmldir "${WINALLQML}"to the windeployqt call, so the whole call looks like this :
C:/Qt/5.12.2/msvc2017_64/bin/windeployqt.exe QtCreatorScrollProject.exe --release --qmldir c:\\Users\\<myUserName>\\Documents\\QtCreatorScrollProject --qmldir c:\\Qt\\5.12.2\\msvc2017_64\\qmlbut I still got the same result (empty window - QML contents doesn't appear).

@just_a_developer Sorry tweaking the arguments didn't help.
What about watching what Qt is printing when you launch the exe?
I would still expect there is a warning or an error printed that would clarify what exactly is going wrong.

Wow! Bravo to "Accessibility Insights for Windows" . That's an amazing trick.
I noticed that earlier you mentioned that the machine where the problem occurs is a VM. I wonder if there is just an OpenGL problem/glitch due to the virtualization. Are there VM options/settings you can play with, like assigning your GPU, or toggling through various graphics acceleration options?

"Are there VM options/settings you can play with, like assigning your GPU, or toggling through various graphics acceleration options?"
I am not sure if there is anything that I could do... It is a machine in vSphere and I don't really see any options that I could change which could be relevant...But : here is a bit more info :
- the app works well under a Windows7 VM (everything appears, including QML contents)
- the app doesn't show the QML contents under Windows8 and Windows10 VMs (empty window - QML contents doesn't appear)
Here is the context of the Windows7 VM (as shown by OpenGL Extension Viewer), where the QML contents does appear :
Here is the context of the Windows10 VM (as shown by OpenGL Extension Viewer), where the QML contents doesn't appear :

OK : I got the fix : it is a rendering issue.
When I force rendering via ANGLE, it works : Options for forcing rendering via ANGLE :
1.: setting theQT_OPENGLenvironment variable toangle. (I only tested this solution, and it works well.)
2.: compile Qt withconfigure ... -angle.
3.: callQCoreApplication::setAttribute(Qt::AA_UseOpenGLES);before creating theQApplicationobject .There is still an interesting thing : based on Qt's documentation, Qt libraries are compiled with
-opengl dynamicwhich means that Qt should fallback to using the ANGLE renderer by itself (without me having to forcefully ask it to do that).
Ref.: https://doc.qt.io/qt-5/windows-requirements.html#graphics-drivers
Ref2.: https://doc.qt.io/qt-5/configure-options.html#opengl-options-for-windowsSo it seems like that this fallback mechanism is broken.
( A bit more info about the different renderers : https://wiki.qt.io/Qt_5_on_Windows_ANGLE_and_OpenGL )
