Hi,
I'm working into implementing a virtual remote keyboard/touch pad daemon for
Linux, currently I'm dumping events into an uinput device, but that is giving
me some trouble with my keyboard layout (which is brazillian, br-abnt2). I was
looking for a way to this 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.
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?
Thank you!
