## Member Function Documentation

static void Gtk::TreeDragDest::add_interface | ( | GType | gtype_implementer | ) | `[static]`

bool Gtk::TreeDragDest::drag_data_received | ( | const TreeModel::Path& | dest,
|  | const SelectionData& | selection_data |
| ) |  |  |

Asks the Gtk::TreeDragDest to insert a row before the path dest, deriving the contents of the row from selection_data.

If dest is outside the tree so that inserting before it is impossible, `false` will be returned. Also, `false` may be returned if the new row is not created for some model-specific reason. Should robustly handle a dest no longer found in the model!

Parameters:

  | dest | Row to drop in front of.
  | selection_data | Data to drop.

Returns:
  Whether a new row was created before position dest.

GtkTreeDragDest* Gtk::TreeDragDest::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Gtk::ListStore, and Gtk::TreeStore.

bool Gtk::TreeDragDest::row_drop_possible | ( | const TreeModel::Path& | dest_path,
|  | const SelectionData& | selection_data |
| ) |  |  | const

Determines whether a drop is possible before the given dest_path, at the same depth as dest_path.

i.e., can we drop the data in selection_data at that location. dest_path does not have to exist; the return value will almost certainly be `false` if the parent of dest_path doesn't exist, though.

Parameters:

  | dest_path | Destination row.
  | selection_data | The data being dragged.

Returns:
  `true` if a drop is possible before dest_path.

## Friends And Related Function Documentation

Glib::RefPtr< Gtk::TreeDragDest > wrap | ( | GtkTreeDragDest * | 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.
