The y-coordinate, in pixels, of a mouse click.

Remarks
Note
The properties pX and pY are in pixels, and not the HIMETRIC units that are associated with the ink space. This is because this event replaces the related mouse event of a pen-unaware application and this type of application understands only pixels.
This event method is defined in the _IInkCollectorEvents, _IInkOverlayEvents, and _IInkPictureEvents dispatch-only interfaces (dispinterfaces) with an ID of DISPID_IPEMouseWheel.
