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.

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.

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.
