gtk-combo-box-text-insert-text (combo position text)

combo -- a gtk-combo-box-text widget
position -- an integer with an index to insert text
text -- a string with the text

Inserts text at the given position in the list of strings stored in the combo box.

If position is negative then the text is appended.
