| 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!
Deprecated: 4.10: Use list models instead
| path | Row that was being dragged. |
true if the row was successfully deleted.
|
protectedvirtual |
| 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!
Deprecated: 4.10: Use list models instead
| path | Row that was dragged. |
Gdk::ContentProvider for the given path.

| 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.
Deprecated: 4.10: Use list models instead
| path | Row on which user is initiating a drag. |
true if the row can be dragged.
