[Editable uitable] Calculate result based on user input

Hi there,

I have created a uitable in GUI. Consists on a nx3 table. The first two columns (A,B) are user input. The third should be the result of a computation (C=A*B). How can I manage to achieve this? This is my current code, in which I initialy input random values.

Thanks a lot,

Filipe

function MyTable
f = figure('Position',[300 300 3000 400]);
% Column names and column format
columnname = {'A','B','C'};
columnformat = {'bank','bank','bank'}; 
% Define the initial displayed data
d =  {randi([0 10],1,1) randi([0 10],1,1) randi([0 10],1,1);}; % I guess this is my first mistake because the third column should be already the result of a computation but I don't know how to do it
% Create the uitable
hTable = uitable(f,'Position',[0 0 3000 400],'Data', d,... 
            'ColumnName', columnname,...
            'ColumnFormat', columnformat,...
            'ColumnEditable', [true true false],... % I set the last to false since it is not supposed to be editable.
            'RowName',[]);      
get(hTable,'Data')        
end

d =  {randi([0 10],1,1) randi([0 10],1,1)};
d{3} = d{1} .* d{2};

Beyond that, you need a CellEditCallbackFcn parameter in the uitable() call to update d{3} based upont he current d{1} and d{2}

Thanks for your answer Walter. I was already able to solve the first part fo my problem. However, I'm quite new to GUI's and the uitable function. Could you tell me how to implement a CellEditCallbackFcn parameter in the uitable()? Maybe with a simple example? Thanks once again,

Filipe

Right click on your table, --> Callbacks --> Add CellEditCallback

This will create a subsection in your app code. Whenever a cell is edited by the user, this function will run.

So you can use this Callback to calculate the result of the table inputs and update the table accordingly.

Thanks a lot. I think it's solved!
