set_reorderable

Description:

public void set_reorderable (bool reorderable)

This function is a convenience function to allow you to reorder models that support the `GtkTreeDragSourceIface` and the `GtkTreeDragDestIface`.

Note:

Use [class@Gtk.ListView] or [class@Gtk.ColumnView] instead

Both `GtkTreeStore` and `GtkListStore` support these. If reorderable is true, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model’s `GtkTreeModel:GtkTreeView:row-inserted` and `GtkTreeModel:GtkTreeView:row-deleted` signals. The reordering is implemented by setting up the tree view as a drag source and destination. Therefore, drag and drop can not be used in a reorderable view for any other purpose.

This function does not give you any degree of control over the order -- any reordering is allowed. If more control is needed, you should probably handle drag and drop manually.

Parameters:

this	A `GtkTreeView`.
reorderable	true, if the tree can be reordered.
