Dear Azrael,

Thanks for the response.

Correct assumption.

Either the entire cell is selected, or none of the cell is selected (unless the
cell is editable).  I can connect callbacks on a mouse click and release, but I
don't think that the position of the cursor within the cell is available. Also,
the entire cell is highlighted, not just the selected text.

I'm thinking of doing something with an editable cell, in which the selected
text is highlighted.  Maybe I can connect a callback to the renderer on the
"edited" signal.  The callback can figure out which row was edited, and can
refresh the text, making it look like the text cannot be altered.  I'm not
sure what the "edited" signal means; if it isn't appropriate, I'll check
out "columns-changed" for GtkTreeView.

Thanks for the help,
Alban
