I fumbled my way through building a very simple Gtk2 app which did recognize the event. But that little test app had a Gtk window, and I want to get away from having any window.X applications cannot receive events unless they have an X window, because it is the X window that receives the event. the gtk+ equivalent is a GdkWindow (the GdkWindow is an abstraction for a windowing system's lowlevel window object, and is an X window in the X11 target). getting keyboard events also requires keyboard focus, so using a hidden window will be tricky magic at best.
It is not true, actualy. Any application may capture events on any window. That is particularly true for the root window. And since all other windows are BELOW the root window, each keypress can be captured on the root window. After all, that's exactly how the window manager keybindings work.
so, if you're wanting to capture the Ctrl key in a terminal app, Gtk2 will not help you at all.
Gtk2 won't. I am not sure how much Gdk would, though. Anyway, the Gnome
Panel installs global keybindings. You can have a look at how it does
that (As far as I recall, it used a key grab, but I am not sure whether
it was a gdk call or a direct X call).
