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.

TreeDragDest& Gtk::TreeDragDest::operator= ( TreeDragDest&& src )

noexcept

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`
	)

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.
