===================
Activate the picker
===================

This example shows how to activate the picker, which is the tool that you
use to select an object in the plotter and get its name.

Relate ``CustomObject`` class with a PyVista mesh
=================================================

.. GENERATED FROM PYTHON SOURCE LINES 38-64

.. code-block:: Python


    import pyvista as pv

    # Note that the ``CustomObject`` class must have a way to get the mesh
    # and a name or ID.

            self.name = "CustomObject"
