- 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
- listStoreSetValue :: ListStore a -> Int -> a -> IO ()
- listStoreToList :: ListStore a -> IO [a]
- listStoreGetSize :: ListStore a -> IO Int
- listStoreInsert :: ListStore a -> Int -> a -> IO ()
- listStorePrepend :: ListStore a -> a -> IO ()

- listStoreClear :: ListStore a -> IO ()
Types
Instances
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 rowSource
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 rowSource
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
listStoreGetValue :: ListStore a -> Int -> IO aSource
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.
listStoreGetSize :: ListStore a -> IO IntSource
Query the number of elements in 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 IntSource
Append an element to the store. Returns the index of the inserted element.
listStoreRemove :: ListStore a -> Int -> IO ()Source
Remove the element at the given index.
listStoreClear :: ListStore a -> IO ()Source
Empty the store.
