Constructors
seqStoreNew :: (Applicative m, MonadIO m) => [a] -> m (SeqStore a) Source #
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 Source #
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 Source #
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 Source #
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 Source #
Extract the value at the given index.
seqStoreSafeGetValue :: MonadIO m => SeqStore a -> Int32 -> m (Maybe a) Source #
Extract the value at the given index.
seqStoreSetValue :: MonadIO m => SeqStore a -> Int32 -> a -> m () Source #
Update the value at the given index. The index must exist.
seqStoreToList :: (Applicative m, MonadIO m) => SeqStore a -> m [a] Source #
Extract all data from the store.
seqStoreGetSize :: (Applicative m, MonadIO m) => SeqStore a -> m Int32 Source #
Query the number of elements in the store.
seqStoreInsert :: MonadIO m => SeqStore a -> Int32 -> a -> m () 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.
seqStoreInsertBefore :: (Applicative m, MonadIO m) => SeqStore a -> TreeIter -> a -> m () Source #
Insert an element in front of the given element.
seqStoreInsertAfter :: (Applicative m, MonadIO m) => SeqStore a -> TreeIter -> a -> m () Source #
Insert an element after the given element.
seqStorePrepend :: (Applicative m, MonadIO m) => SeqStore a -> a -> m () Source #
Prepend the element to the store.
seqStoreAppend :: MonadIO m => SeqStore a -> a -> m Int32 Source #
Append an element to the store. Returns the index of the inserted element.
seqStoreRemove :: MonadIO m => SeqStore a -> Int32 -> m () Source #
Remove the element at the given index.
seqStoreClear :: MonadIO m => SeqStore a -> m () Source #
Empty the store.
