[Scilab-users] Recognition of cursor key as input

[stephane.mottelet at utc.fr]

  Hello,

IMHO, the only way to trap a keypress and get the ascii (?) code is to use
the event_handler callback of a figure :

function handler(x,y,ibut)
//
endfunction

f=gcf();
f.event_handler='handler';
​f.event_handle_enable='on';

On my computer, I have the following mapping 

left arrow pressed : ibut=37 (released=-37)
up arrow : 38
right arrow 39
down arrow 40

The problem is that you need to have a figure opened, and that this figure
must have the focus.
