MATLAB: Non-existent handles field uitable1

guihandlesuitable

Im trying to display data on a previously empty uitable created in guide. But when i try to use

h=handles.uitable1;
set(h,'Data',handles.wide)

in its script, i get an error saying

 Reference to non-existent field 'uitable1'.

so i've inserted a test line

disp(handles)

which actually didn't show a part for uitable1 or any other gui elements. what should i do?

after some more research i've just found what's wrong.

its about the way i run it. i was double-clicking the .fig file in the current folder.(i thought 2 files were running together when i did this.)

writing the common name for .fig and .m file in the command window creates 'handles.uitable1'

thanks.

MATLAB: I need assistant making uitable

thx walter. I guess i have to show you the code. Do give some comments.

These are my button callback:

function add_pushbutton_Callback(hObject, eventdata, handles)

cost1 = cell2mat(get(handles.uitable1,'Data'));

mwlimits1 = cell2mat(get(handles.uitable2,'Data'));

Pdt = str2num(get(handles.input3_editText,'String'));

lambda1 = mat2cell(lambda);

set(handles.answer1_staticText,'Data', lambda1);

Pgg1 = mat2cell(Pgg);

set(handles.answer2_staticText,'Data', Pgg1);

totalcost1 = num2str(totalcost);

set(handles.answer3_staticText,'Data', totalcost1);

guidata(hObject, handles);

This are my uitable callback that you suggest:

handles.uitable1 = hObject;

guidata(hObject,handles);

These are my edit text callback:

function input1_editText_Callback(hObject, eventdata, handles)

input = str2num(get(hObject,'String'));

if (isempty(input))

    set(hObject,'String','0')

end

guidata(hObject, handles);

function input1_editText_CreateFcn(hObject, eventdata, handles)

if ispc && isequal(get(hObject,'BackgroundColor'),

get(0,'defaultUicontrolBackgroundColor'))

     set(hObject,'BackgroundColor','white');

end

So basically, i have a figure with 3 input from user which includes 2 uitables and 1 edit text. And i have to push buttons and i have to generate the answer into 3 which is lambda,pgg1 and totalcost. So what do you think.. Thank you again =)

MATLAB: Error using handle.handle/set Invalid or deleted object.

In your callback for edit1 you replace the handle with the value extracted from the handle. That is confusing at the very least.
