|Interfaces for drag-and-drop support in TreeView.
|TreeViews provide special support for
Drag-and-Drop such as hover-to-open-rows or autoscrolling. This module
implements two utility functions that set and get a path and a model in a
Selection structure. These functions
are thus useful to implement drag-and-drop functionality in a
TreeModel. In fact, they are used as part of
the default drag-and-drop interfaces of
TreeStore that allows to permute rows and move
them between hierarchy levels.
|treeModelEqual :: (TreeModelClass tm1, TreeModelClass tm2) => tm1 -> tm2 -> Bool|
|Compare two tree model for equality.
|treeGetRowDragData :: SelectionDataM (Maybe (TreeModel, TreePath))|
|Obtains a TreeModel and a path from SelectionDataM whenever the target name is
GTK_TREE_MODEL_ROW. Normally called from a treeDragDestDragDataReceived handler.
|treeSetRowDragData :: TreeModelClass treeModel => treeModel -> TreePath -> SelectionDataM Bool|
Sets selection data with the target name GTK_TREE_MODEL_ROW, consisting
of a TreeModel and a TreePath. Normally used in a
- Returns True if setting the data was successful.
