I'm working into implementing a virtual remote keyboard/touch pad
daemon for Linux, currently I'm dumping events into an uinput

in X, found XTestFakeKeyEvent and was wondering if I could make it
simpler and cross-platform using GDK3. I tried this attached code,
but it doesn't do anything. I was wondering if someone has done
this before and know what I'm doing wrong or if I should just give
up doing with GDK.
The context is a little different, but the attached function works,
given a pointers to an existing GtkWidget and GdkEvent.
Also, this is an extra, if I can't just fake key events, what
should I use to map unicode chars into linux/input.h event key
codes based on my keyboard layout on X? What about Wayland?
man xmodmap ?
