Thread Subject: Problems with checkbox

Hi all,

I'm having an issue with the 'checkbox' in a GUI I'm working on. The problem is that regardless if the checkbox is marked or not, the handle always has the same value. The handle hcheckhold is always 4.0248... I need to have 2 different values! here's the code


hcheckhold = uicontrol('Style','checkbox','String','Hold',...
    'Min',0,'Max',1,...
    'Position',[10,10,10,10],...
    'FontSize',10,'Callback',{@checkbox_Callback})

function checkbox_Callback(source,eventdata)
        hcheckhold
end

Any help?

get(hcheckhold,'Value')

Thanks Walter,

I pasted it inside the function and it worked perfectly,

Thanks again

Dear Matthias,

The problem is solved already.
Did it get clear, that the handle itself must not change its value? The handle is a unique pointer to the object, while the property 'Value' of the object can change its value.

Kind regards, Jan
