LabVIEW Tree Control - Setting Item symbol to 41 programmatically (Break or horizontal line)

[PMN1966]

Hi 

How to set the Tree control Item Symbol to 41 programmatically?

Its possible to do it when the VI is not running.

Please see attached example.

Hi PMN,

there are several methods available for Tree controls, one of them is called "Custom Item Symbols.Set Symbol": you can always add your own symbols and decide their index in the symbols array…

Hi GerdW

I know, but the Custom Item Symbol will only set the Item symbol in Column number 1 and not the horizontal line through ALL column

as shown at the picture on the VI.

The Symbol 41 will also clear all other text at the line. (like a new page brake)

Hi PMN,

well, that's some special feature and is not "symbol 41".

With my LV2017 installation the line break is shown in a different position to indicate it is not a default "symbol"…

Hi GerdW

Ok but is it possible to set it programmatically?

Hi PMN,

I haven't found a (programmatic) way to insert that linebreak in a tree so far. But I don't use treee controls often…

Set the value to -1.

I found it by manually inserting the break.  Then running the property node to tell me the value of the item symbol for that item.
