ok, so we at least move forward. I will check this icon issue, how to
do it
in qt properly.

It's not the icon, it's the WM_CLASS. It should be enough to just override
the passed argv[0] to the QApplication constructor, restoring the
behaviour
before YaST launched with argv[0] == "ruby"

and that's the part that is not so easy, as libyui obtain it from /proc

see
https://github.com/libyui/libyui-qt/blob/
817ddbe637c98a54460b1152ec9d51e7f2d9422e/src/YQUI.cc#L126

in past it works due to this dirty hack, but we no longer want such nasty
hack. So we need find better way to pass it
https://github.com/libyui/libyui-qt/blob/
817ddbe637c98a54460b1152ec9d51e7f2d9422e/src/YQUI.cc#L141

Maybe QCoreApplication::setApplicationName("YaST2") works here. As YaST does
not use QSettings, that shouldn't have any ill side effects

that is what we already doing, so title is correct, but for not known reason
yet, no effect for icon

https://github.com/libyui/libyui-qt/blob/master/src/YQApplication.cc#L777

maybe we need to call also this
qApp->setWindowIcon ( QIcon ( pixmap ) );
to some predefined icon for yast, but I am not sure how it works with all
modules, as it probably have own icons.
