TreeStore.setColumnTypes

void setColumnTypes(gobject.types.GType[] types)

Sets the type of the columns in a tree store.

This function is meant primarily for types that inherit from gtk.tree_store.TreeStore, and should only be used when constructing a new gtk.tree_store.TreeStore.

This functions cannot be called after a row has been added, or a method on the gtk.tree_model.TreeModel interface is called on the tree store.
