Multi-row selection can be used with a DISPLAY ARRAY
controlling a TREE container. However, because of the
tree-view ergonomic differences with simple tables, the selection of tree
nodes follows some specific rules:
- When selecting a range of nodes, only visible nodes will get the
selection flag. For example, if you select all nodes with Ctrl-A,
and if the root node is collapsed, only the root node will be
selected. This applies also when selecting nodes by program with the
DIALOG.setSelectionRange().
- Collapsing a node will de-select all child nodes.
