Hello, can you add a callback function that sets the hierarchical expansion and shrinkage icons of the tree widget?

I've seen several UI libraries that provide this feature, can you support it? If you're busy dealing with other issues, I can try PR

Yes, it would be good to support this. I will get to this eventually, but you can do a PR if you want to speed things up. I would recommend adding the same three icon fields that are on switch to treeview (IconOn, IconOff, IconUnk), and then passing them when the switch icons are set (currently on line 363 of treeview.go). Also, for future reference, it would be better to file bugs and feature requests as issues instead of discussions if possible.
