gtk:tree-store-set-column-types (store types)

store -- a gtk:tree-store object
types -- a list with the g:type-t type IDs, one for each column

This function is meant primarily for GObjects that inherit from the gtk:tree-store class, and should only be used when constructing a new gtk:tree-store object. It will not function after a row has been added, or a method on a gtk:tree-model object is called. The gtk:tree-store implementation is deprecated since 4.10. Use the gtk:tree-list-model object instead.
