GtkCList::set_column_resizeable
Lets you specify whether a specified column should be resizeable by the user. Note that turning on resizeability for the column will automatically shut off auto-resizing, but turning off resizeability will NOT turn on auto-resizing. This must be done manually via a call to set_column_auto_resize.
