Dave Pearson	728acc27c0	Introduce an exception specific to handling an unknown node ID ... See https://github.com/Textualize/textual/pull/1535#discussion_r1065873649	2023-01-10 14:57:35 +00:00
Dave Pearson	6ea68cc112	Add Tree.get_node_by_id ... The thinking here is that a user of a Tree may want to relate notes to other parts of their UI, or other data in their application. While this could be done by keeping a reference to the node itself, it could also be beneficial to just track the ID. Given that ID is a public property of a TreeNode, but given it doesn't currently have any other (public) purpose, this seems to add some useful symmetry.	2023-01-10 10:42:07 +00:00
