| 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:
trueif the row was successfully deleted.

| bool Gtk::TreeDragSource::drag_data_get | ( | const TreeModel::Path& | path, | |
| SelectionData& | selection_data | |||
| ) |
Asks the Gtk::TreeDragSource to fill in selection_data with a representation of the row at path.
selection_data->target gives the required type of the data. Should robustly handle a path no longer found in the model!
- Parameters:
-
path Row that was dragged. selection_data A Gtk::SelectionData to fill with data from the dragged row.
- Returns:
trueif data of the required type was provided.

| 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:
trueif the row can be dragged.

| Glib::RefPtr< Gtk::TreeDragSource > wrap | ( | GtkTreeDragSource * | object, | |
| bool | take_copy = false | |||
| ) | [related] |
A Glib::wrap() method for this object.
- Parameters:
-
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.
