A way to code a HUD in Linux?

[Javier V.]

I want to code some sort of HUD, this is, a transparent desktop layer
that will react when some hotkeys are pressed, just like those notebooks
special keys that draw volumen icons on the desktop.

Would you use gtk for this? SDL?

Any idea?

XOSD should do the job?

well, I thought using Xlib and checking xosd sourcecode, but then found
that ruby xlib wrappers are really outdated.

i think xlib will be the only way for this
