Using symbols in a multicolumn listbox

[DougFerguson]

I can't seem to show symbols in the second column of a multicolumn listbox. I tried some example code I found on NI.com and there seems to be something unique about the multicolumn list box they used in the example. If I put down a new one it doesn't work. What's the trick?

Can you show us what is the code you are using and also your work? (2009 version please)

Did the example use Row Headers?  That's the only thing that makes sense to me.

Hi Doug,

did you enable symbols at all?

Here are my findings from my quick playing around.

• The symbols have to be made visible (right-click, Visible menu).
• Only the first colum of data can have symbols.  The property is a 1D array.  Doesn't make much sense to me, but whatever.
• You can have Row Headers (also in right-click, Visible menu).  You can then color these headers to make them look like actual data.  This will make it look like the second colum has the symbols.  You also have to write to the row headers via another property (Row Header Strings).

The following statement was copied from the LabVIEW Help topic "Adding Symbols to Listboxes and Tree Controls":

Note  In a multicolumn listbox, LabVIEW adds the symbol to the first column.

In my own experimentation, I havent found a way to add symbols to the other columns. Is it possible that the examples you've found are really just adding symbols into the text itself? I agree with the previous post, we'll need to see the code you're working with.

I am assuming you are referring to this example: Inserting Images in a Multicolumn Listbox in LabVIEW 8.x. For a multicolumn listbox, that only works for the first column. If you want symbols on other columns, then one way to do this is to set that column to a font that uses symbols, like the example for showing folders that I showed.

Nope, I am using this example.

I edited this code and added symbols to a third column and it only shows up in the control 'MC Listbox'.

That example appears to use a custom control, rather than a standard multicolumn listbox. Without investigating it, I'm not sure how it was done.

Hi Doug,

Can you clarify what you are trying to do?  You mentioned that you modified the example.  What modifications were made? Can you please attach your code?

Thanks,
