Difference between "change" and "end" in VSlider

[juanprietob]

I have a series of VSlider defined as:

vuetify.VSlider(
    v_model=("tx", 0), 
    min=-1.0, max=1, step=0.01,
    hide_details=True, dense=True,
    change=OnTransformSliderChange, # <- the issue is that the change event is only executed after the slider is released
    # end=OnTransformSliderChange # The "change" slot behaves the same as the "end" slot
)

The sliders control the translation and rotation of an object. I want the object to update as I move the sliders. I have the following update function:

def OnTransformSliderChange():
    translation = np.array([state.tx, state.ty, state.tz])
    rotation_angles = np.array([state.rx, state.ry, state.rz])
    vc.OnTransformSliderChange(translation, rotation_angles)
    ctrl.view_update()

Why is the behavior similar to the "end" event?
Why is the "change" event only triggered when the slider is released?

That is what is described in the vuetify documentation for that component.

If you want constant update you need to use input=OnTransformSliderChange. But I would not recommend doing that.

Instead simply listen on "tx" change. That will happen continuously while not over subscribing the server.

@state.change("tx")
def OnTransformSliderChange(tx, **kwargs):
    ...
