or here: https://forum.qt.io/topic/61899/qt5-embedded-framebuffer-poor-gui/4 .... and than in stack : https://stackoverflow.com/questions/50236156/making-a-qt-gui-application-run-on-a-framebuffer-in-linux ....
never interested first on these framebuffer .... but seems quite old type and not very interesting because if you use qt on old pc or xxxxxxPI and other project, you can use QT framework as windows manager without all SO and drive Lcnc from these point, without start a complete linux SO. I think these way perform same result than use framebuffer (on same hardware) but with more feature. New version of QT like 12 or 14 is focused on embedded linux system ... so better is use it. regards Il giorno dom 22 mar 2020 alle ore 11:54 theman whosoldtheworld <bleachk...@gmail.com> ha scritto: > > But you use qtquick framebuffer? ... because is only for media.Any ho > have you see on qt fortum? for example here: > https://forum.qt.io/topic/63561/qt-qml-on-linux-framebuffer ?? > > regards > > Il giorno dom 22 mar 2020 alle ore 08:18 Thomas J Powderly > <tjt...@gmail.com> ha scritto: > > > > @ Frank Tkalcevic > > Hello > > > > Could you tell more about how you got QT to output to /dev/fb0? > > > > > > I installed Qt Creator > > > > (Qt Creator 4.2.0 Based on Qt 5.7.1 (GCC 6.3.0 20170415, 64 bit) > > and followed tutorial to produce a small app, > > it has a window, 3 buttons and an icon . > > > > > > Code moves the icon into the rect clicked on.
