Constructors

seqStoreNew :: (Applicative m, MonadIO m) => [a] -> m (SeqStore a)

Create a new TreeModel that contains a list of elements.

Arguments

:: (Applicative m, MonadIO m)

=> [a]

the initial content of the model

-> Maybe (DragSourceIface SeqStore a)

an optional interface for drags

-> Maybe (DragDestIface SeqStore a)

an optional interface to handle drops

-> m (SeqStore 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

seqStoreDefaultDragSourceIface :: DragSourceIface SeqStore row

Default drag functions for SeqStore. 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.

seqStoreDefaultDragDestIface :: DragDestIface SeqStore row

Default drop functions for SeqStore. 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

seqStoreIterToIndex :: (Applicative m, MonadIO m) => TreeIter -> m Int32

Convert a TreeIterRaw to an an index into the SeqStore. Note that this function merely extracts the second element of the TreeIterRaw.

seqStoreGetValue :: (Applicative m, MonadIO m) => SeqStore a -> Int32 -> m a

Extract the value at the given index.

seqStoreSafeGetValue :: MonadIO m => SeqStore a -> Int32 -> m (Maybe a)

Extract the value at the given index.

seqStoreSetValue :: MonadIO m => SeqStore a -> Int32 -> a -> m ()

Update the value at the given index. The index must exist.

seqStoreToList :: (Applicative m, MonadIO m) => SeqStore a -> m [a]

Extract all data from the store.

seqStoreGetSize :: (Applicative m, MonadIO m) => SeqStore a -> m Int32

Query the number of elements in the store.

seqStoreInsert :: MonadIO m => SeqStore a -> Int32 -> a -> m ()

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.

seqStoreInsertBefore :: (Applicative m, MonadIO m) => SeqStore a -> TreeIter -> a -> m ()

Insert an element in front of the given element.

seqStoreInsertAfter :: (Applicative m, MonadIO m) => SeqStore a -> TreeIter -> a -> m ()

Insert an element after the given element.

seqStorePrepend :: (Applicative m, MonadIO m) => SeqStore a -> a -> m ()

Prepend the element to the store.

seqStoreAppend :: MonadIO m => SeqStore a -> a -> m Int32

Append an element to the store. Returns the index of the inserted element.

seqStoreRemove :: MonadIO m => SeqStore a -> Int32 -> m ()

Remove the element at the given index.

seqStoreClear :: MonadIO m => SeqStore a -> m ()

Empty the store.
