Hmm. This is the default behavior of the treeview widget, and Gtk
deliberately makes style decisions very hard to override, since
people all have different themes and it's best to let them choose.

One close thing I could do is set the "hover-selection" property,
which would actually select the item the mouse is on. This would
be a nightmare, I imagine, for people who bat their mice haphazardly
to the left to get their cursor out of the way.


Another, more sensible thing I can do is to change the rendering
of the color swatch when the mouse is on the row. Can you think
of a good "highlighted" cue that only affects the swatch?

Ditto -- this is the default behavior of the treeview. I'm catching
mouse clicks anyway so that visibility works without selecting each
row, so it wouldn't be hard to throw away non-left-clicks.

I think I'll do this - right-clicking also selects the row, which
will probably irritate people expecting a popup menu. Best to make
selection a left-click-only action.
