Members

dragDataReceived bool dragDataReceived(TreePath dest, Value value): Asks the #GtkTreeDragDest to insert a row before the path @dest, deriving the contents of the row from @value. 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!
getTreeDragDestStruct GtkTreeDragDest* getTreeDragDestStruct(bool transferOwnership): Get the main Gtk struct
rowDropPossible bool rowDropPossible(TreePath destPath, Value value): 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 @value 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.
