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.

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.

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.
