GtkCTree::node_get_text
Returns the column text of a given row.
The column in which the expanders/lines are visible cannot use this
function (nTreeGraphic in the Constructor).
You have to use
node_get_pixtext
in this case.
Note that this function can also not be used if you used the functions
node_set_pixtext or
node_set_pixmap to
that column. You should use
node_get_pixtext
instead.
