I have a plugin that creates a toolbar using the cmake function paraview\_plugin\_add\_toolbar(). Is there a way that other code in my plugin can access and call methods on the toolbar instance that gets created by paraview?

Qt has API to get access to the `QMainWindow` instances in the application and then you can get access to QToolBar instances in each of those windows.
see `pqCoreUtilities::findMainWindow`, `pqCoreUtilities::mainWidget` for how to access the main window.
