| Synopsis |
|
|
|
|
| Detail
|
|
| A RowReference is an index into a
Graphics.UI.Gtk.ModelView.TreeModel.TreeModel that is persistent even if
rows are inserted, deleted or reordered.
|
|
| Types
|
|
| data TreeRowReference |
| Tree Row Reference : like a TreePath it points to a subtree or node, but
it is persistent. It identifies the same node (so long as it exists) even
when items are added, removed, or reordered.
|
|
|
| Constructors
|
|
| treeRowReferenceNew :: TreeModelClass self => self -> TreePath -> IO (Maybe TreeRowReference) |
| Creates a row reference based on a path. This reference will keep pointing
to the node pointed to by the given path, so long as it exists. Returns Nothing if there is no node at the given path.
|
|
| Methods
|
|
| treeRowReferenceGetPath :: TreeRowReference -> IO TreePath |
Returns a path that the row reference currently points to.
- The returned path may be the empty list if the reference was invalid.
|
|
| treeRowReferenceValid :: TreeRowReference -> IO Bool |
| Returns True if the reference refers to a current valid path.
