nanogui: Thread: GrGetFocus only if keyboard is available?

Hi again,

I tried to get the wid of the actual displayed window with GrGetFocus(). 
Without success. Is that, because I switched the keyboard device (in config) 
to No Keyboard? How can I get the actual displayed window ID without setting 
a keybord?

Besides, if I use a PC Keyboerd, which one do I have to choose? It isn't the 
scankeyboard, isn't it?

Thank you,
Olaf

You can't use GrGetFocus() to get the ID of any displayed window, 
since there may be many windows displayed.  Perhaps we need to
have a routine to get the ID of the "active" window, but this is a little
more complicated.  You can use GrSetFocus() even if you don't have
a keyboard, but the focus only applies to a single window, not the
window's parents, or frame.

Normally, the TTYSCAN keyboard should be used for Linux, since it
returns scancodes.  It will work with any keyboard that Linux allows
for its internal tty driver.
