GtkTreeItem Constructor
GtkTreeItem
(string
node_text
);
Creates a new instance of GtkTreeItem with node_text as the node label. The new item should be added to a GtkTree using append() , prepend() , or insert() .
Strictly speaking node_text is optional. That is, you will not get a run time error if you do not supply the text, but if no text is given the node will not display.
