IOleInPlaceSite::Scroll

Tells the container to scroll the view of the object by a specified number of pixels.

HRESULT Scroll(

SIZE scrollExtent	//Number of pixels
);

Parameter

scrollExtent

[in] Contains the number of pixels by which to scroll in the X and Y directions.

Return Values

S_OK

The method successfully executed the view scroll instruction.

E_INVALIDARG

An invalid argument.

E_UNEXPECTED

An unexpected error occurred.

Comments

As a result of scrolling, the object's visible rectangle can change. If that happens, the container should give the new ClipRect to the object by calling IOleInPlaceObject::SetObjectRects. The intersection of the ClipRect and PosRect rectangles gives the new visible rectangle. See IOleInPlaceSite::GetWindowContext for a discussion of ClipRect and PosRect.

Notes to Callers

Called by an active, in-place object when it is asking the container to scroll.
