My app keeps crashing and i've never used the Debugger befor!

@Kris-Revi
Yes but it didnt show anything interesting.
Do you call FullScreen any where ?
seems to start there.

Also, does other examples work ?
Could be openGL setup that is messed up.

[Kris Revi]

@mrjj weird hmmm so i found the bit of code that was the cause!

    const QScreen* screen = qApp->primaryScreen();
    w.setGeometry( QRect(QPoint(0,0), screen->geometry().size()) );
    w.setWindowFlag(Qt::MaximizeUsingFullscreenGeometryHint,true);

    w.showFullScreen();

but when i now run my App it's loading and "running" but no window comes up :S

[mrjj]

@Kris-Revi
Did you remove the fullscreen or how did you make it run ?

Try with
w.show()

[Kris Revi]

@mrjj so i added w.show(); and ran the debugger again and got this

[mrjj]

@Kris-Revi

Ok so it is when it tries to show the render surface.

You have to try some of the openGl examples and see.

I guess its your openGL since it seems to crash on showing.

https://doc.qt.io/qt-5/qtopengl-hellogl2-example.html

They are available directly in creator.

@mrjj so i just ran that example and it worked without problems

[Kris Revi]

@mrjj i just noticed this

QQuickWidget is only supported on OpenGL. Use QQuickWindow::setGraphicsApi() to override the default.

could this be it?

@Kris-Revi

Hi
yes it could very well as normally Desktop is using openGl and mobile some other ES? but
normally it's automatic.

This is a Desktop pc windows right ?

Did you compile Qt your self ?

Maybe its a Qt6 thing. try setting it to openGl via the setGraphicsApi as it says and then see.

[Kris Revi]

@mrjj yea it's for desktop now :) 6.2.0 but im compiling for both Android and Desktop in same project! and wanted to test the App on the Desktop

[mrjj]

@Kris-Revi

Can it be that on startup some other API is set ?
Or you added some defines to .pro so it thinks its Android ?

[Kris Revi]

@mrjj so the App works perfectly with QQuickWindow::setGraphicsApi(QSGRendererInterface::OpenGL); weird why i would need to set that tho :S hmmm

[Kris Revi]

@mrjj question in the pro file can't i do this

win32
{
    CONFIG(release, debug|release): LIBS += -LC:\QMsgPack\bin -lqmsgpack
    INCLUDEPATH += C:\QMsgPack\bin
    DEPENDPATH += C:\QMsgPack\bin
}

win32
{
    CONFIG(debug, debug|release): LIBS += -LC:\QMsgPack\bin -lqmsgpack
    INCLUDEPATH += C:\QMsgPack\bin
    DEPENDPATH += C:\QMsgPack\bin
}
unix
{
    contains(ANDROID_TARGET_ARCH,arm64-v8a)
    {
        ANDROID_PACKAGE_SOURCE_DIR = \
           $$PWD/android

        ANDROID_EXTRA_LIBS = \
            $$PWD/android/libs/libqmsgpack_arm64-v8a.so
    }
    LIBS += -L$$PWD/android/libs/ -lqmsgpack_arm64-v8a

    INCLUDEPATH += $$PWD/android/libs
    DEPENDPATH += $$PWD/android/libs
}

? :S

[mrjj]

@Kris-Revi
Yes that seems perfect. should not interfere with which backend is used.

I cant tell either. Did you use any new Qt6 things ?
Could be fun to see if it does the same say in 5.12

[Kris Revi]

@mrjj for some reason with the code above it does this

i've selected the Desktop but it is trying to find the "arm / android" version :S
