Bug ID: 14071
Summary: -platform linuxfb:fb=/dev/fb0:rotation=180 does not
rotate a Qt5 application
Product: buildroot
Version: 2021.05
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned@buildroot.uclibc.org
Reporter: sbartolett@thorlabs.com
CC: buildroot@uclibc.org
Target Milestone: ---
I am trying to rotate a Qt5 application 180 degrees using the linuxfb
rotation=180 setting but it seems to be ignored. I've tried other linuxfb
options such as offset but these also seems to be ignored. Are these options
supported under buildroot?
I've tried:
./test -platform linuxfb:fb=/dev/fb0:rotation=180
./test -platform linuxfb:rotation=180
./test -platform linuxfb:fb=/dev/fb0:rotation:180
I've also tried setting teh environment varaible QT_QPA_PLATFORM. But in all
case the application to runs normally (not rotated).
I did find this patch:
https://borkedlabs.com/blog/2015/06-01-qt5-linuxfb-rotation-for-lcds/, but it
is from 2015 so I would assunme this issue would have been fixed by now.
