Contents

Description

Standard model to store list data.

Synopsis

Types

Constructors

listStoreNew :: [a] -> IO (ListStore a) Source #

Create a new TreeModel that contains a list of elements.

listStoreNewDND Source #

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 #

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 Source #

Extract the value at the given index.

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.

listStoreGetSize :: ListStore a -> IO Int Source #

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 Int Source #

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.
