Parent only select in tree controls

[miguelc]

Is it possible to set a tree control so that ONLY the parents are selectable and the children are disabled (i.e. a child tag will not be present in the output of the tree on the block diagram and the children won't highlight when a user tries to press them)?

You can use the Point To Row Column method along with the Mouse Down? filter event to determine the tag of the item that was clicked...and if it was a child, discard the click.  You would have to do something similar with the Key Down? filter event if you don't want people navigating to child items with the arrow keys as well:

The Point To Row Column method is only available in LabVIEW 8.0 and later.  If you are in LabVIEW 7.x, you need to use the Point to Row-Col.vi in vi.lib\tree.

Good luck,
