[Scilab-users] xclick with output argument cdmenu

[Jens Simon Strom]

Hello Rafael,
getcolor( ) was the best source. It led to

xdel()
x=[-1  +1];
winnum=1;   win=string(winnum);
cf=figure(winnum);
plot(x,x)
C=["Green"  "Red"  "Abort"];//case name strings
addmenu(winnum,  C(1));  C1="execstr("+C(1)+"_"+win+"(1))";    
addmenu(winnum,  C(2));  C2="execstr("+C(2)+"_"+win+"(1))";
addmenu(winnum,  C(3));  C3="execstr("+C(3)+"_"+win+"(1))";
while  %t
   [!,!,!,!,cbmenu]=xclick();
   //Get the clicked option by cbmenu
   if  cbmenu==C1,  cf.background=3;  end
   if  cbmenu==C2,  cf.background=5;  end
   if  cbmenu==C3,  break,  end
end

where the necessity of execstr( ) is quite unintuitive to me.

Using uimenu( ) in the alternate script

xdel()
x=[-1  +1];
winnum=1;   win=string(winnum);
cf=figure(winnum);
plot(x,x)
C=["Green"  "Red"  "Abort"];//case name strings
uimenu('label',C(1),'callback','t1=%t');
uimenu('label',C(2),'callback','t2=%t');
uimenu('label',C(3),'callback','t3=%t');
while  1
   t1=%f;t2=%f;t3=%f;
   sleep(100)
   if  t1,  cf.background=3;  end
   if  t2,  cf.background=5;  end
   if  t3==%t,  break,  end
end

does the same andis easier to understand. However it needs the sleep. I could not adapt the uimenu( ) approach to xclick in order to avoid the hectic loop.

Kind regards
Jens
