You’ll want to use the ‘setSelectionRows()’ method of the underlying tree component. Here is a little code snippet that I set on a button to select a couple items on a default Vision Tree View component.

```auto
from javax.swing.tree import TreeSelectionModel

# get the underlying tree component
tree_component = event.source.parent.getComponent('Tree View').getComponent(0).getComponent(0)

#set our selection model to allow discontiguous selection (e.g., select rows 1 and 3 but not 2)
tree_component.getSelectionModel().setSelectionMode(TreeSelectionModel.DISCONTIGUOUS_TREE_SELECTION)

# the rows we want to select
selected_rows = [2,4]

# now apply the selection to the component
tree_component.setSelectionRows(selected_rows)
```

You’ll just need to work your selection logic into populating a list like ‘selection\_rows’. Hope this helps!
