i need assistant making uitable

Guyz.. I need assistant about making GUI in matlab.. I wan to make 2 tables n 1 pushbutton. My prob is i cannot callback the data from the table to the pushbuttons.. These are my callback data for uitable1 n uitable2:

*table = get(hObject,'Data');

handles = guidata(hObject);

handles.table = table;

guidata(hObject, handles);**BOLD TEXT*

And then i put these coding into pushbuttons:

*handles = guidata(hObject);

table = handles.table;

table = cell2mat(table);

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

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

Pdt1 = get(handles.input3_editText,'String');

guidata(hObject, handles);

cost = cell2mat(cost1);

mwlimits = cell2mat(mwlimits1);

Pdt = str2num(Pdt1);**BOLD TEXT*

Can anyone help me pls~~

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 =)

* lambda is not defined at the time it is used in add_pushbutton_Callback

* There is no Data property for any uicontrol Style, or for text boxes. If you want to set the text displayed for handles.answer1_staticText then you should set the String property, and it should be set to a character array or a cell string array, not a numeric array.

* Pgg is not defined in add_pushbutton_Callback at the time it is used.

* 'String' vs 'Data' for handles.answer2_staticText and handles.answer3_staticText. Setting Data would be okay if answer1_staticText and answer2_staticText were uitable but then they would be badly misnamed.

* as you do not modify the handles structure itself any of the callbacks, you do not need to

guidata(hObject, handles);

in them.

thx again walter.. i think i have to compkete the data first. One anothere question.

I want the data table will be 3 by 3 matrix but when i make a table figure, it is automatically 4 by 2 table. When i change the row at the property inspector, i delete the 4th row but when i apply, the row does not delete. Why is this happen? How i can make it become 3 by 3 table?

[Walter Roberson]

Sorry no idea on changing the table size in Guide or through the property inspector.

[slumberk]

owh.. ok.. thx again

[Walter Roberson]

Your callback for uitable1 should be

handles.uitable1 = hObject;
guidata(hObject,handles);

Likewise for uitable2 except setting handles.uitable2

Then your callback for the pushbutton would be like,

cost1 = cell2mat(get(handles.uitable1,'Data'));
mwlimits1 = cell2mat(get(handles.uitable2,'Data'));
Pdt = str2num(get(handles.input3_editText,'String'));

but you haven't shown any code for actually doing anything with these matrices and number once you have them, so I cannot advise past this point.

The rest of the code you show for your callbacks appears to be unnecessary if you are working in Guide -- though starting with

handles = guidata(hObject);

would be needed if you were doing your own callback programming instead of having the callbacks generated by GUIDE.

This appears to be a continuation of your previous question, #924 and should probably have been posted as part of that.
