List of all members.

## Public Member Functions
bool | 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.
bool | 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 .
const GtkTreeDragSource* | gobj () const
| Provides access to the underlying C GObject.
GtkTreeDragSource* | gobj ()
| Provides access to the underlying C GObject.
bool | 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.

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.

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: `true` if data of the required type was provided.

const GtkTreeDragSource* Gtk::TreeDragSource::gobj | ( |  | ) | const`[inline]`

| Provides access to the underlying C GObject. Reimplemented from Glib::Interface. Reimplemented in Gtk::ListStore, and Gtk::TreeStore.

GtkTreeDragSource* Gtk::TreeDragSource::gobj | ( |  | ) | `[inline]`

| Provides access to the underlying C GObject. Reimplemented from Glib::Interface. Reimplemented in Gtk::ListStore, and Gtk::TreeStore.

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.

## Friends And Related Function Documentation

Glib::RefPtr<Gtk::TreeDragSource> wrap | ( | GtkTreeDragSource* | object,
|  | bool | take_copy = `false`
| ) | `[related]`

  | 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.
