Constructors
listStoreNew :: [a] -> IO (ListStore a)
Create a new TreeModel that contains a list of elements.
listStoreNewDND
::
=> [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
Default drag functions for Graphics.UI.Gtk.ModelView.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
Default drop functions for Graphics.UI.Gtk.ModelView.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
Convert a TreeIter to an an index into the ListStore. Note that this function merely extracts the second element of the TreeIter.
listStoreGetValue :: ListStore a -> Int -> IO a
Extract the value at the given index.
listStoreSetValue :: ListStore a -> Int -> a -> IO ()
Update the value at the given index. The index must exist.
listStoreToList :: ListStore a -> IO [a]
Extract all data from the store.
listStoreGetSize :: ListStore a -> IO Int
Query the number of elements in the store.
listStoreInsert :: ListStore a -> Int -> a -> IO ()
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 ()
Prepend the element to the store.
listStoreAppend :: ListStore a -> a -> IO Int
Append an element to the store. Returns the index of the inserted element.
listStoreRemove :: ListStore a -> Int -> IO ()
Remove the element at the given index.
listStoreClear :: ListStore a -> IO ()
Empty the store.
