Methods
dragDataDelete
treeDragSourceDragDataDelete Source #
:: (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 #
:: (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 #
:: (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.
