[Scilab-users] problem with GUI pushbutton callback

[Dang, Christophe]

Hello,

I had a small example that used to work,
and does not anylonger.

// Example

// ********************

f = scf(0);

e = uicontrol(f, "style", "edit", ...
    "position", [0 0 100 20]);

t = uicontrol(f, 'style', 'text',...
    "position", [200 0 100 20], ...
    "string", "...");

b = uicontrol(f, "string", "$x^2$",...
    "position", [100 0 100 20], ...
    "callback", "x = eval(e.string);...
        y = x^2;...
        t.string = string(y);...
        plot2d(x, y, style = -1);");

// ********************

when I try to use it, I get a

%_h = 
      !--error 2 
Facteur invalide.
at line       2 of function %eval called by :  
at line      19 of function eval called by :  
:13e35c75130:-7b0f");x = eval(e.string); y = x^2; t.string = stri
while executing a callback.

Has anything changed in the GUI that makes my code obsolete?

Regards
