UItable CellSelectionCallback

How do I get the position of a call when I select it in a uitable? I know you can associate a CellSelectionCallback with a table, but what is the property to pull? A similar question two years ago said the proper field is Indices but this doesn't seem to work for me (Note, I am using R2008a). I would be expecting get(t,'Indices') to do the trick for me (t is the table), but such a field isn't recognized.

The CellSelectionCallback will be passed a minimum of two parameters, the first of which will be the uitable handle, and the second of which is the event data, which people commonly program to be received into the variable named "event". For CellSelectionCallback, event will be a structure which will have one field named "Indices" and it is that you want to look at.

For example,

function GasPricesTable_Selection_CB(src, event)
  selected_cells = event.Indices;

Sorry, but what is the event data and how do you grab it?

Hello, can anyone clarify this eventdata point? Still haven't been able to get it implemented.

Who did bump this thread and why? Is the question still open?

Not sure, Eugene might simply have Accepted the answer: that bumps it.

This solves my problem.... maybe it'll help some of you guys..

1) right click on the table, select 'CellSelectionCallback'. An automated function will be generated for you (displayed in the property Inspector - also right click the table to select).

E.g mine is "@(hObject,eventdata)NmodeDataRead_v10('data_uitable_CellSelectionCallback',hObject,eventdata,guidata(hObject))'"

2) This function will be added to your codes.

function data_uitable_CellSelectionCallback(hObject, eventdata, handles)
% hObject    handle to data_uitable (see GCBO)
% eventdata  structure with the following fields (see MATLAB.UI.CONTROL.TABLE)
%  Indices: row and column indices of the cell(s) currently selecteds
% handles    structure with handles and user data (see GUIDATA)
% disp(eventdata)
handles.datatable_row = eventdata.Indices(1);
handles.datatable_col = eventdata.Indices(2);
guidata(hObject, handles);

Just add the lines of codes above to get the indices...

hope this helps.
