sourcefn drag_data_delete(&self, path: &TreePath) -> bool
👎Deprecated: Since 4.10
fn drag_data_delete(&self, path: &TreePath) -> bool
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!
§Deprecated since 4.10
Use list models instead
§path
row that was being dragged
§Returns
true
if the row was successfully deleted
sourcefn drag_data_get(&self, path: &TreePath) -> Option<ContentProvider>
👎Deprecated: Since 4.10
fn drag_data_get(&self, path: &TreePath) -> Option<ContentProvider>
Asks the TreeDragSource
to return a gdk::ContentProvider
representing
the row at @path. Should robustly handle a @path no
longer found in the model!
§Deprecated since 4.10
Use list models instead
§path
row that was dragged
§Returns
a gdk::ContentProvider
for the
given @path
sourcefn row_draggable(&self, path: &TreePath) -> bool
👎Deprecated: Since 4.10
fn row_draggable(&self, path: &TreePath) -> bool
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.
§Deprecated since 4.10
Use list models instead
§path
row on which user is initiating a drag
§Returns
true
if the row can be dragged
