First, I'm wondering what are the FNCTreeView properties that are referring to "Title" such as
There is nothing about that in the documentation. What is the Title used for ?
There is an example in the documentation for adding a custom editor with a TTrackBar.
Is it the same mechanism if I want to add a button in one of the columns ?
Is there another way as this is not really an editor but just allowing an action for each TreeView node ?
What is your recommendation here ?
