- listStoreNewDND :: [a] -> Maybe (DragSourceIface ListStore a) -> Maybe (DragDestIface ListStore a) -> IO (ListStore a)
- listStoreDefaultDragSourceIface :: DragSourceIface ListStore row
- listStoreDefaultDragDestIface :: DragDestIface ListStore row
- listStoreIterToIndex :: TreeIter -> Int
- listStoreGetValue :: ListStore a -> Int -> IO a
- listStoreSafeGetValue :: ListStore a -> Int -> IO (Maybe a)
- listStoreSetValue :: ListStore a -> Int -> a -> IO ()
- listStoreToList :: ListStore a -> IO [a]
- listStoreGetSize :: ListStore a -> IO Int
- listStoreInsert :: ListStore a -> Int -> a -> IO ()

- listStoreClear :: ListStore a -> IO ()
Types

Constructors
listStoreNew :: [a] -> IO (ListStore a) Source #
Create a new TreeModel that contains a list of elements.
Arguments
| :: [a] | the initial content of the model |
| -> Maybe (DragSourceIface ListStore a) | an optional interface for drags |
| -> Maybe (DragDestIface ListStore a) | an optional interface to handle drops |
| -> IO (ListStore a) | the new model |
Create a new TreeModel that contains a list of elements. In addition, specify two
interfaces for drag and drop.
Implementation of Interfaces
listStoreDefaultDragSourceIface :: DragSourceIface ListStore row Source #
Default drag functions for ListStore. These
functions allow the rows of the model to serve as drag source. Any row is
allowed to be dragged and the data set in the SelectionDataM object is
set with treeSetRowDragData, i.e. it contains the model and the
TreePath to the row.
listStoreDefaultDragDestIface :: DragDestIface ListStore row Source #
Default drop functions for ListStore. These
functions accept a row and insert the row into the new location if it is
dragged into a tree view
that uses the same model.
Methods
listStoreIterToIndex :: TreeIter -> Int Source #
listStoreSafeGetValue :: ListStore a -> Int -> IO (Maybe a) Source #
Extract the value at the given index.
listStoreSetValue :: ListStore a -> Int -> a -> IO () Source #
Update the value at the given index. The index must exist.
listStoreToList :: ListStore a -> IO [a] Source #
Extract all data from the store.
listStoreInsert :: ListStore a -> Int -> a -> IO () Source #
Insert an element in front of the given element. The element is appended if the index is greater or equal to the size of the list.
listStorePrepend :: ListStore a -> a -> IO () Source #
Prepend the element to the store.
listStoreAppend :: ListStore a -> a -> IO Int Source #
Append an element to the store. Returns the index of the inserted element.
listStoreClear :: ListStore a -> IO () Source #
Empty the store.
