[gtkmm] refTreeSelection->select(iter);

hello all,

does selecting a row in a treeview really work? I can scroll to a row, but 
selecting it just doesn't work...

I have a treeview in which each row can have children that refer to another 
row. Can anyone point to what I'm doing wrong when trying to scroll to the 
referenced row when double clicked:

//////////////////////////////////////////////////
refTreeSelection = gui_tv->get_selection();

// which row was double clicked?
iter = refTreeSelection->get_selected();

if (!iter) {return;} // If nothing is selected

row = *iter;

//some code that finds which row we want to scroll to
...
i = row[gui_dc->col_offset];
...


// the row that contains the reference is the beginpoint of the search // 
for the referenced row
iter = row.parent();
row = *iter;

// code that finds the row pointed to

while ((... some condition with regard to i...))
{ iter++; row = *iter; }

p = gui_ts->get_path(iter);

// this works
gui_tv->scroll_to_row(p, 0.5);


// but this doesn't, either with or without the first line
refTreeSelection = gui_tv->get_selection();
refTreeSelection->select(iter);

/////////////////////////////////////////////////////////

thanks in advance!
Danny.
