I am trying to create my own interactorStyle and I need to be able to change the camera pitch by clicking on the left mouse button **while** moving the mouse horizontally. Can anyone indicate how to achieve this or point towards an example where this or similar is accomplished. Thanks

I think you should use in internal flag toggled by the button pressed and then use a `if` statement in the mouse move handler.

Take a look at this [https://kitware.github.io/vtk-examples/site/Python/Interaction/MouseEvents/](https://kitware.github.io/vtk-examples/site/Python/Interaction/MouseEvents/)
