: 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?
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.

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