createListDisplay :: Eq a => Behavior [a] -> (forall store. (TreeModelClass (store a), TypedTreeModelClass store) => ReaderT (TreeView, store a) IO b) -> Now (TreeView, Behavior (Maybe a))

Creates a TreeView displauying a dynamic list. The columns and cell renderers are defined using reader monads built from the other functions in this module.In this casem the cells must be polymorphic in the type of store they accept so as to ensure read-only behavior. Returns the TreeView and the curently-selected item.

tvColumn :: Text -> ReaderT (TreeViewColumn, store) IO b -> ReaderT (TreeView, store) IO TreeViewColumn

Add a column with the given title and renderers to the enclosing TreeView.

tvTextDisplay :: (CellLayoutClass col, TreeModelClass (store a), TypedTreeModelClass store) => (a -> Text) -> ReaderT (col, store a) IO CellRendererText

Add a cell renderer diaplaying a text-valued function of a row to a column.

tvShowDisplay :: (CellLayoutClass col, TreeModelClass (store a), TypedTreeModelClass store, Show b) => (a -> b) -> ReaderT (col, store a) IO CellRendererText

Add a cell renderer diaplaying a s function of a row using Show. Useful for Int values.
