# Simple Treeview with traits

Since we are continuously receiving inquiries regarding the work with Rainbow5(TM) radar data, I will present here a nice way of visualizing the dictionary representation of an arbitrary Rainbow5 file.

This code snippet makes use of the python packages traits and traitsui.

Installing traits is as easy as:

    :::bash
    $ pip install traitsui

By adapting this gist a treeview representation of the loaded dictionary is given in a simple qt-gui:

<script src="https://gist.github.com/wradlib/9037b8a67dfbcff3b7de.js"></script>

Now you can browse the contents of your versatile Rainbow5 data file and examine the needed dictionary-keys to fit in your data loading routine.
