Yes it's required:

While you're at it, write yourself another little function to call your
other little function ( above ) when the focus leaves the Combo's entry,
because Combo's don't automatically detect if someone types a string
into their entry that matches an item in their model ( ie the correct
iter is only set as 'active' if you use the *mouse* to select an item
... any keyboard input is ignored ! ):

And look out if you try to get a value out of a CellRendererCombo in a
TreeView:

IMHO there are *far* too many combo-related bugs in gtk+ :( Don't the
developers use combos?
