gtk:combo-box-text-insert-text (combo pos text)

combo -- a gtk:combo-box-text widget
pos -- 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 the pos argument is negative then the text is appended. This is the same as calling the gtk:combo-box-text-insert function with a nil ID string. The gtk:combo-box-text implementation is deprecated since 4.10. Use the gtk:drop-down widget instead.
