  - ScalingMouseWheelListener
```
public ScalingMouseWheelListener()
```
    Creates a new ScalingMouseWheelListener without an updater.
    Note:
    Without an updater manually registered painters will not be updated and therefore won't reflect the updated scaling. This only works in combination with theme styling, as the painter update is implemented in the themes internally.
  - ScalingMouseWheelListener
```
public ScalingMouseWheelListener(Consumer<IConfigRegistry> updater)
```
    Creates a new ScalingMouseWheelListener with the given updater.
    
    Parameters:
    
    updater - The updater that should be called on zoom operations. Needed to reflect the updated scaling. E.g. re-register ImagePainters like the CheckBoxPainter, otherwise the images will not be updated according to the scaling.
