Description
Slightly related to #1396 in that to do it now the ability to change a TreeNode.label
would be required. At the moment it is possible to use Tree.clear
to clear all the nodes under the root node, but there appears to be no public interface for totally clearing a Tree
and repopulating it from scratch -- other that performing a remove
on the widget itself and then a mount
of a fresh instance.
A use case for this would be if the Tree
is being used to view the content of a file in a structured way, and you want the user to be able to load in a new file.
