InkPicture.MouseWheel event

Occurs when the mouse wheel moves while the InkPicture control has focus.

Syntax

void MouseWheel(
  [in]      InkMouseButton           Button,
  [in]      InkShiftKeyModifierFlags Shift,
  [in]      long                     Delta,
  [in]      long                     x,
  [in]      long                     y,
  [in, out] VARIANT_BOOL             *Cancel
);

Parameters

Button [in]

The button that was pressed.

Shift [in]

The state of the SHIFT key.

Delta [in]

The distance that the mouse wheel turned.

x [in]

The x-coordinate, in pixels, of the IInkCursor object.

y [in]

The y-coordinate, in pixels, of the IInkCursor object.

Cancel [in, out]

VARIANT_TRUE to cancel the MouseWheel event for the parent control; otherwise, VARIANT_FALSE.

Return value

This event does not return a value.

Remarks

Note

The parameters x and y are in pixels, and not the HIMETRIC units that are associated with the ink space coordinate system. This is because this event replaces the related mouse event of an application that is not pen-aware, and that type of application refers only to pixels.

This event method is defined in the _IInkPictureEvents interface. The _IInkPictureEvents interface implements the IDispatch interface with an identifier of DISPID_IPEMouseWheel.
