[Scilab-users] uicontrol & wiki

[paul.carrico at free.fr]

Hi

I've been looking to the wiki and an interesting article speaking about
GUI developments
(https://fr.wikibooks.org/wiki/Découvrir_Scilab/Créer_une_interface_graphique_GUI
- in French language). 

I've a naive question on the code hereafter: why is it possible to
implement several values? no loop is needed nor any breack condition ...
surprising but I do not understand :-) (naive question I confess) 

Thanks 

Paul 

ps: implement a value in the bottom left box and  click on the
pushbutton x^2

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