Re: Using different signals depending on which row of of a treeview

[Mike Martin <mike redtux plus com>]

This is more or less what I did except I added a signal_connect separately
to the visibilty (which is in a cell_data_function on first renderer)

ie: (perl)
my @cells=Treeview->get_column(n)->get_cells;
then
$cells[n]->signal_connect(blah
}
);
(where n is the appropriate number of column/renderer)
