Current qualitative deepening pass for the FROG Tree widget family
FROG — Free Open Graphical Language
The Tree family now has a fuller public surface for hierarchical navigation and structured selection:
- structured
frog.treevalue model, - node id and node path posture,
- selection and active node posture,
- expansion state,
- optional checkbox / tri-state posture,
- viewport, search, and filter posture,
- editing posture,
- optional drag/drop posture,
- node row, expander, connector, icon, label, selection, active-node, edit, drag, and drop parts.
Tree remains a finite hierarchical widget family. Filesystem APIs, database browsers, object reflection, scene graphs, and IDE-private navigators remain downstream integrations unless explicitly standardized elsewhere.
