    The icons in the control can be any icons, the snapshots only happen to contain such Mac oriented icons.


    To install the TreeView plugin you have to create a folder called Plugins in the same folder as your Xojo or Real Studio application is located in and drop the TreeView plugin and the CoreClasses plugin into it.

    (Please note that we no longer test for Real Studio if for some reason something does not work for you on Real Studio then please request older version of the TreeView plugin).

    In this documentation you will notice that there are two types of indexes and it varies from functions and context which index you are working on. It is very important to understand the indexes well.
