nested function in uicontrol callback

Hi all,

nested functions do NOT work inside uicontrol callback.
Try this example as an m-file:
%%%%%%%%% start code: function file ttt.m %%%%%%%%%%%%%%%%

function ttt
uicontrol('Style', 'checkbox', 'Units','normalized', ...
'Position', [0.01 0.25 .08 .05],...
'Callback', ['mmm']);

function mmm
x=3
%%%%%% end of code %%%%%%%%%%%%%%%%
Any tip?
I do not want to create an extra m-file!
Thanx a lot ... Start a New Thread

Hello,
Well i guess you have to try to make it first working in a separate .m file
and then you try to make it as a nested function.

and remove [ ] from the function name .. and hit it a try again

Hello:
You can nest functions but when you use callbacks there is a trick.
Try this code:

/function ttt
uicontrol('Style', 'checkbox', 'Units','normalized', ...
'Position', [0.01 0.25 .08 .05],...
'Callback', @mmm);

function mmm(hObject,eventdata)
x=3
end
end/

Let me know how it works.
Best regards,
Juan
