About the mouse move event

The example provides an example about how to implement user-self mouse event:

from vedo import *


def onLeftClick(mesh):
    printc("Left   button pressed on", [mesh], c="g")


def onMiddleClick(mesh):
    printc("Middle button pressed on", [mesh], c="y")


def onRightClick(mesh):
    printc("Right  button pressed on", [mesh], c="r")


vp = Plotter()

vp.load(datadir+"teapot.vtk").c("gold")

vp.mouseLeftClickFunction   = onLeftClick
vp.mouseMiddleClickFunction = onMiddleClick
vp.mouseRightClickFunction  = onRightClick

printc("Click object to trigger function call", invert=1, box="-")

vp += __doc__
vp.show()

The above code shows the left/middle/right click event. I wonder how to implement the mouse move event?

In addition, the onLeftClick is called by:

        plotter::_mouseleft(self, iren, event):
             ...vedo code
             if self.mouseLeftClickFunction:
                 self.mouseLeftClickFunction(clickedActor)

Actually, the vedo will finish some code, and then call self.mouseLeftClickFunction(clickedActor). If I don’t need the ...vedo code, I want vedo can directly call my-self onLeftClick, how can I achieve this purpose? Thank you in advance.

@marcomusy Really thank you for your very nice reply.

@marcomusy Thank you very much. vp.interactor.RemoveAllObservers() is what I want. I can remove all observers, and add what I want. In this way, I can control all the event call back funtion.
