How can I create a button to return the indices of a uitable selection?

Hello,

I have created a simple uitable to display the contents of an N x 1 array, A: g=uitable(f,'Data',A, ....). In essence it is a menu of things to choose from. I would like to select values from the uitable and create a uicontrol button to return the indices of my selection.

I have seen multiple entries for things like event.Indices, CellSelectionCallback, etc. but I am having a hard time understanding it.

Thank you in advance

Hi,

Here is an example script that creates an 'uitable' with a 'CellSelectionCallback' that retrieves the indices of the selected cells. Further, on the callback for the pushbutton, the values are displayed on the screen.

 %function example
%Doc example for uitable
f = figure('Position',[100 100 400 150]);
dat =  {6.125, 456.3457;...
        6.75,  510.2342;...   
        7,     658.2;};
columnname =   {'Rate', 'Amount'};
columnformat = {'numeric', 'bank'};
columneditable =  [false false]; 
t = uitable('Units','normalized','Position',...
            [0.1 0.1 0.9 0.9], 'Data', dat,... 
            'ColumnName', columnname,...
            'ColumnFormat', columnformat,...
            'ColumnEditable', columneditable,...
            'RowName',[],...
            'CellSelectionCallback',@mycb); %Add cellselectioncallback
%Add pushbutton        
uicontrol('style','pushbutton','callback',@(~,~)pbcb(t),... %give handle to table
    'units','normalized','position',[0 0 0.4 0.2],'string','Return Selection');
end
function mycb(src,evt)
    set(src,'UserData',evt.Indices); %Make indices available to everyone through the UITABLE's userdata
end             
function pbcb(t)
    for i=1:size(t.UserData,1)
        x(i)=t.Data(t.UserData(i,1),t.UserData(i,2));
    end
    if size(x,1)==0
        error('Please select the Data');
    else
        disp(x);
    end
end
