bool Gtk::TreeDragSource::drag_data_delete | ( | const TreeModel::Path& | path | ) |
Asks the Gtk::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!
- Parameters
-
path Row that was being dragged.
- Returns
true
if the row was successfully deleted.

Glib::RefPtr<Gdk::ContentProvider> Gtk::TreeDragSource::drag_data_get | ( | const TreeModel::Path& | path | ) | const |
Asks the Gtk::TreeDragSource to return a Gdk::ContentProvider representing the row at path.
Should robustly handle a path no longer found in the model!
- Parameters
-
path Row that was dragged.
- Returns
- A Gdk::ContentProvider for the given path or
nullptr
if none exists.

bool Gtk::TreeDragSource::row_draggable | ( | const TreeModel::Path& | path | ) | const |
Asks the Gtk::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.
- Parameters
-
path Row on which user is initiating a drag.
- Returns
true
if the row can be dragged.

object The C instance. take_copy False if the result should take ownership of the C instance. True if it should take a new copy or ref.
- Returns
- A C++ instance that wraps this C instance.
