Hello Humberto,

I also tried two more examples of qt5_gui module (qtbase/examples/gui),
the rasterwindow and analogclock. To include these examples in the
compilation mechanism of Genode I relied on the example
"qt5_openglwindow". Both examples compiled correctly, but do not run as
they should. I tried it on Qemu with pbxa9 using the foc kernel.
could you provide a Genode branch on github or a patch with the changes
you made, so I can easily reproduce the problem?

First I want to explain that I am not an expert in application
development QT, nor do I have much experience in working with the
framework Genode, but I'm interested in checking the proper functioning
of Qt in Genode.
I continued examining the trace of the error in the execution of example
qt5_rasterwindow.
This is my partial conclusion of the problem:
When the rasterwindow application (defined in
qtbase/examples/gui/rasterwindow/rasterwindow.cpp) run the 108 line
(QPaintDevice *device = m_backingStore->paintDevice()), this ends
calling the function QPaintDevice
*QNitpickerWindowSurface::paintDevice() (defined in
repos/libports/src/lib/qt5/qtbase/src/plugins/platforms/nitpicker/qnitpickerwindowsurface.cpp).
This implementation of paintDevice() function fails in the 62 line
(QRect geo = _platform_window->geometry();).
I do not know much about the integration between Nitpicker of Genode and
Qt. I apologize for my lack of technical language.
Any idea what is happening?
Thank you for the cooperation.
Sincerely
Humberto.
