[Qt-interest] QTableView Selection

[Kenneth Beck]

I have a very simple data model, amenable to showing in a table, I 
think, but the behavior of table view is not acting consistently, or at 
least not the way I expect. First, I set Behavior and Mode to only allow 
the user to select individual complete rows:
       periodsList->setSelectionBehavior(QTableView::SelectRows);
       periodsList->setSelectionMode(QTableView::SingleSelection);
Now, when the table appears, the only way to select whole rows is to 
mouse click on a tiny rectangle that appears to the left of the row. 
clicking on any one cell does NOT select the row (the behavior I want).
What am I doing wrong here?

Second, I need to operate on the selected row. I have tried both of the 
approaches below, they both return 0 for size of the returned list, when 
there is clearly an entire row selected:

QModelIndexList milst0=periodsList->selectionModel()->selectedRows(1);
QModelIndexList milst0=periodsList->selectionModel()->selection().indexes();

I have also tried
QModelIndex ndx=periodsList->selectionModel()->currentIndex();
which does return a valid index, but it may not be in my selected row, 
it may be in another cell that the user just clicked!

Anything obvious wrong here? Should I be using a TreeView?
