GtkTreeView

[Calum Grant <calumg onetel com>]

I'm trying to

1) Put a vertical scroll bar in a GtkTreeView widget.  Surely a 
GtkScrolledWindow would also scroll the column headings, which is not 
what I want.

2) Allow a user to toggle a GtkCellRendererToggle.  This should update 
an underlying G_TYPE_BOOLEAN field in the GtkTreeStore.

Unfortunately I have got stuck on both of these.  Any help would be 
appreciated,
