Function gtk::tree_get_row_drag_data[][src]

pub fn tree_get_row_drag_data(
    selection_data: &SelectionData
) -> Option<(Option<TreeModel>, Option<TreePath>)>
Expand description

Obtains a tree_model and path from selection data of target type GTK_TREE_MODEL_ROW. Normally called from a drag_data_received handler. This function can only be used if selection_data originates from the same process that’s calling this function, because a pointer to the tree model is being passed around. If you aren’t in the same process, then you’ll get memory corruption. In the TreeDragDest drag_data_received handler, you can assume that selection data of type GTK_TREE_MODEL_ROW is in from the current process. The returned path must be freed with gtk_tree_path_free().
