Methods
Overloaded methods
dragDataDelete
treeDragSourceDragDataDelete Source #
Arguments
| :: (HasCallStack, MonadIO m, IsTreeDragSource a) | |
| => a |
|
| -> TreePath |
|
| -> m Bool | Returns: |
Asks the TreeDragSource to delete the row at path, because
it was moved somewhere else via drag-and-drop. Returns False
if the deletion fails because path no longer exists, or for
some model-specific reason. Should robustly handle a path no
longer found in the model!
dragDataGet
treeDragSourceDragDataGet Source #
Arguments
| :: (HasCallStack, MonadIO m, IsTreeDragSource a) | |
| => a |
|
| -> TreePath |
|
| -> SelectionData |
|
| -> m Bool | Returns: |
Asks the TreeDragSource to fill in selectionData with a
representation of the row at path. selectionData->target gives
the required type of the data. Should robustly handle a path no
longer found in the model!
rowDraggable
treeDragSourceRowDraggable Source #
Arguments
| :: (HasCallStack, MonadIO m, IsTreeDragSource a) | |
| => a |
|
| -> TreePath |
|
| -> m Bool | Returns: |
Asks the TreeDragSource whether a particular row can be used as
the source of a DND operation. If the source doesn’t implement
this interface, the row is assumed draggable.
