I have a paraview plugin that generates a mesh, the user can manually go to into the pipeline and hit refresh to view the mesh. I am wondering if there is a way to automatically refresh the filter’s parent file in the pipeline or refresh the entire pipeline all from within the plugin? I would like the mesh to automatically refresh when it is created or transformed from the plugin.

Are there any c++ functions that would auto-refresh if it is not a built in function? Auto-apply setting takes care of half the problem

Hi,

You may consider to take a look at this answer:

> Hi, In the code of [VeloView](https://github.com/Kitware/VeloView) (which basically is a bundled ParaView+LidarPlugin), the timesteps of ParaView is changed by the main code, not the Lidar Plugin. We advice you to start from VeloView code, which is much closer to your goal. If you really want to start from scratch within ParaView, you need to increment this requested timestep yourself. Newest version of VeloView (unreleased) uses the same mechanism as ParaView “LiveSource” plugin (available in 5.6+), where the plugin tells ParaVi…

HTH.
