The event handling function works asynchronously (may be during the
execution of another function....)
instruction like res=return (x*2) will store the result in the current
execution context which unknown if Scilab is not at prompt level when
the handling function is executed
It is better to use global variable:
function myEventHandler(win,x,y,ibut)
global res
res=x*2
endfunction
You can then recover the value everywhere by
global res;disp(res)
or to store the result into the user data field of the figure in which
the evenet handler has been called
function myEventHandler(win,x,y,ibut)
fig=get_figure_handle(win)
set(fig, "user_data", struct("myres",x*2))
endfunction
You can then recover the value everywhere using
fig=get_figure_handle(win)
disp(fig.user_data.myres)

how can i return the a value from an event handling function
ie:
seteventhandler('myEventHandler(win,x,y,ibut)')
function val=myEventHandler(win,x,y,ibut)
return x*2
endfunction
where should i find "val" to use it later in the code ?
