Thanks Eric. I tried swapping the margin for border width and now I get
a warning for every item I add to the grid. Plus I don't want a wide
border all around the widget, I just want to add some space on the left.
I see that margin-left has been replaced by margin-start but I don't see
that in the version of Glade I'm using and I'm not convinced that it
would behave any differently.
The solution is to pack the grid into an alignment widget and set the
left padding.
Cheers,
