Hi,
You can find it simply with a little help from google/qwant/duckduckgo/ect.
* https://stackoverflow.com/questions/56601993/how-to-rotate-a-qt5-application-using-the-linux-framebuffer
To summarize:
1. Without changing code :
QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0:rotation=180
1. With using QGraphicsScene and QGraphicsView::rotate()
Regards
Fabrice

Betreff: [Interest] LinuxFB rotation configuration
Hi,
As there is an environment variable QT_QPA_EGLFS_ROTATION to specify the rotation applied to software rendered content in QWidget based applications.
Can you let me know if we have similar environment variable for LinuxFB to rotate Qt5 widget applications?
Thanks and Regards,
Ramakanth
