Tree control how to add custom icon to column

[Vandy_Gan]

Hello everyone,

I want to implement a similar function in the image. You can add or set icons in other columns of the tree control. How should I do this function?

thanks a lot.

You've probably already found some stuff but here is an old thread that talks a bit about it.  It is an unofficial feature that NI seemingly never finished, or never documented.

INI keys can help you, or I think you can copy a MCLB that has the feature enabled. Another solution I've done in the past is to have a 2D picture box on top of the control, then having that be an image that you can set. This gets way more complicated with scrolling, and resizing windows, but it allows you to have glyphs that aren't the default size which is also what I wanted.
