Getting default symbol bmp's from Listboxes/Tree controls

[Mellroth]

Hi,

I'd like to be able to get the current symbol from a selected item in a Tree-control or Listbox control.

It is possible to do this for custom symbols, but I'd like to be able to do this for the built in symbols as well.

Does anyone know if this is possible, or do I have to create bmp's of all built in symbols from Screenshots?

I seem to remember that the built in symbols were accessible just like the custom symbols, but with indexes of 0-39 (0 being blank)..as long as you didn't over-write them with your own symbols at runtime. Is this not the case?

See here.

Thanks Orko,

I was probably a bit unclear in my first post.

Built in symbols are accessible for usage, but in my case I'd like to be able to retrieve the actual pictures being used, regardless if it is a custom symbol or a built in symbol.

From the link you posted;

You can use the Custom Item Symbols:Get Symbol and Custom Item Symbols:Get Symbol Array methods only to retrieve custom symbols. If you use these methods with symbols of indexes 1 through 40, these methods return images only for any custom symbols that overwrite the built-in defaults.

The question is whether there is a way around this to actually get the pictures representing the built in symbols?

Ah. I see. Well, in that case... nope.

Custom symbols in Tree controls and MCLs? And this feature has been in LabVIEW since 8.0? How did I miss this feature?

What don't you do it programatically, this is pretty easy.

Note: While writing a quick example for you I found a LV bug, so look at this http://forums.lavag.org/Buffer-reuse-gone-wrong-t12015.html' target="_blank">thread for the VI. This should be good enough (bug or no bug) for your use case.

I had a look at the other thread, very nice little VI :thumbup: Thanks!

I first tried to go for a built in method to access the bmp's, but as I realized it could not be done, I also decided to get the images programmatically.

So far I haven't got the time to do it, and now you spoil all my fun

so look at this

for the VI.

Oh yeah...that's where I remembered it from! :-) Thanks for the link, PJM.
