+ * #GtkToolItem<!-- -->s cannot be added directly to an #GtkToolPalette, instead they

+ * The easiest way to use drag and drop with GtkToolPalette is to call gtk_tool_palette_add_drag_dest()
+ * with the desired drag source @palette and the desired drag target @widget. Than gtk_tool_palette_get_drag_item()
+ * can be used to get the dragged item in the #GtkWidget::drag-data-received signal handler of the drag target.
