Graphics.UI.Gtk.ModelView.CustomStore

A CustomTreeModel is backed by a Gtk2HsStore which is an instance of the GtkTreeModel GInterface it also stores some extra per-model-type private data

Instances

GObjectClass (CustomTreeModel private row)

TreeModelClass (CustomTreeModel private row)

data TreeModelFlags

These flags indicate various properties of a TreeModel.

If a model has TreeModelItersPersist set, iterators remain valid after a TreeModel signal was emitted.
The TreeModelListOnly flag is set if the rows are arranged in a simple flat list. This is set in the ListStore implementation.

Constructors

TreeModelItersPersist
TreeModelListOnly

Instances

Bounded TreeModelFlags

Enum TreeModelFlags

Flags TreeModelFlags

data DragSourceIface model row

Constructors

DragSourceIface

treeDragSourceRowDraggable :: (model row -> TreePath -> IO Bool)
treeDragSourceDragDataGet :: (model row -> TreePath -> SelectionDataM Bool)
treeDragSourceDragDataDelete :: (model row -> TreePath -> IO Bool)

data DragDestIface model row

Constructors

DragDestIface

treeDragDestRowDropPossible :: (model row -> TreePath -> SelectionDataM Bool)
treeDragDestDragDataReceived :: (model row -> TreePath -> SelectionDataM Bool)

customTreeModelNew

:: (TreeModelClass (model row), TypedTreeModelClass model)
=> private	Any private data the store needs to store. Usually an IORef.
-> (CustomTreeModel private row -> model row)
-> TreeModelIface row	Functions necessary to implement the `TreeModel` interface.
-> Maybe (DragSourceIface model row)	Functions to enable this store to generate drag events.
-> Maybe (DragDestIface model row)	Functions to enable this store to receive drag events.
-> IO (model row)
Create a new store that implements the `TreeModelIface` interface and optionally the `DragSourceIface` and the `DragDestIface`. If the latter two are set to `Nothing` a dummy interface is substituted that rejects every drag and drop.

treeModelGetRow :: TypedTreeModelClass model => model row -> TreeIter -> IO row

customTreeModelGetPrivate :: CustomTreeModel private row -> private

customTreeModelGetStamp :: CustomTreeModel private row -> IO CInt

customTreeModelInvalidateIters :: CustomTreeModel private row -> IO ()

Extracting a specific datum from the row-oriented store for

data ColumnId row ty

The type of a tree column.

Instances

Eq (ColumnId row ty)

Show (ColumnId row ty)

makeColumnIdInt :: Int -> ColumnId row Int

Create a ColumnId to extract an integer.

makeColumnIdBool :: Int -> ColumnId row Bool

Create a ColumnId to extract an Boolean.

makeColumnIdString :: Int -> ColumnId row String

Create a ColumnId to extract an string.

makeColumnIdPixbuf :: Int -> ColumnId row Pixbuf

Create a ColumnId to extract an Pixbuf.

columnIdToNumber :: ColumnId row ty -> Int

Convert a ColumnId to a bare number.

invalidColumnId :: ColumnId row ty

The invalid ColumnId. Widgets use this value if no column id has been set.

treeModelSetColumn

:: TypedTreeModelClass model
=> model row	the store in which to allocate a new column
-> ColumnId row ty	the column that should be set
-> (row -> ty)	the function that sets the property
-> IO ()	returns the newly assigned column
Set or update a column mapping.
