How to save data from a GUI edit box to table using push button?

I am trying to figure out a way to import data from 3 edit boxes using 1 push button to a table. Please help me with that. I want to say thank you in advance!

Dang - use the handles structure that is passed in as the third parameter to the push button callback to get the handles to the three edit text controls. If the table is part of your GUI (i.e. an uitable) then you would again use the handles structure to get the table handle and use that to update the table. For example,

 function pushbutton1_Callback(hObject, eventdata, handles)

 % get the string data from the three edit controls
 str1 = char(get(handles.edit1,'String'));
 str2 = char(get(handles.edit2,'String'));
 str3 = char(get(handles.edit3,'String'));

 % do some work 

 % update the table
 set(handles.uitable1,'Data',data);

where data is an mxn cell array of data that you wish to display within your table.

Thank you Geoff Hayes. One more question is that: for each time I add a group of data into the table, there will be one more slot for the next time to add new data, and the old data is saved. How to do that?

Hi Dang - you will want to update the existing data (within the table) with the new row (or rows) of data. For example, suppose I want to add two random integers to my table whenever I press a push button. I could do something like

function pushbutton1_Callback(hObject, eventdata, handles)

% create the random numbers
x = {randi(42,1,1)  randi(42,1,1)};

% get the current table data
data = get(handles.uitable1,'Data');
if isempty(data)
    data = x;
else
    % append the new row
    data = [data ; x];
end

% update the table
set(handles.uitable1,'Data',data);

That works effectively. Thanks a lot :D
