Thread Subject: Get selected cells in a table

Hello,
Anybody knows how to get selected cells (row and column indices) in a uitable? Thanks.

Anyone has an idea? When a number of cells in a uitable are selected, how do I get their row and column indices in my program?

Thanks.

I have the same question. Is there anyone out there with a solution? Thank you in advance.

First you download findjobj from the file exchange. Then...

figure
u=uitable('data',magic(10))
uu=findjobj(u)
rows=uu.getComponent(0).getComponent(0).getSelectedRows+1
cols=uu.getComponent(0).getComponent(0).getSelectedColumns+1

A little hack not needing findjobj:
The problem is that the only time the selection indices are available is in the "CellSelectionCallback" function, which only gets triggered when the selection was originally made. All I do is re-route that callback to store the result in "UserData" as follows:

f = figure('Position', [100 100 752 350]);
t = uitable('Parent', f, 'Data', cell(3,5), 'Position', [25 25 700 200],'CellSelectionCallback',@(src,evnt)set(src,'UserData',evnt.Indices))

>> get(t,'UserData')

ans =

     []

% Make a table selection...

>> get(t,'UserData')

ans =

     1 2
     2 2
     2 4

Thanks,
Sven.
