IOleInPlaceObject::SetObjectRects method

Specifies how much of the in-place object is to be visible.

Syntax


HRESULT SetObjectRects(
  [in]  LPCRECT lprcPosRect,
  [in]  LPCRECT lprcClipRect
);

Parameters

lprcPosRect [in]

A pointer to the RECT structure containing the position of the in-place object using the client coordinates of its parent window.

lprcClipRect [in]

A pointer to the outer rectangle containing the in-place object's position rectangle (lprcPosRect). This rectangle is relative to the client area of the object's parent window.

Return value

This method returns S_OK on success. Other possible return values include the following.

Return codeDescription
E_INVALIDARG

The specified pointer is invalid.

E_OUTOFMEMORY

There is insufficient memory available for the operation.

E_UNEXPECTED

An unexpected error has occurred.

 

Remarks

It is possible for lprcClipRect to change without lprcPosRect changing.

The size of an in-place object's rectangle is always calculated in pixels. This is different from other OLE object's visualizations, which are in HIMETRIC.

Note  While executing IOleInPlaceObject::SetObjectRects, do not make calls to the PeekMessage or GetMessage functions, or a dialog box. Doing so may cause the system to deadlock. There are further restrictions on which OLE interface methods and functions can be called from within IOleInPlaceObject::SetObjectRects.

Notes to Callers

The container should call IOleInPlaceObject::SetObjectRects whenever the window position of the in-place object and/or the visible part of the in-place object changes.

Notes to Implementers

The object must size its in-place window to match the intersection of lprcPosRect and lprcClipRect. The object must also draw its contents into the object's in-place window so that proper clipping takes place.

The object should compare its width and height with those provided by its container (conveyed through lprcPosRect). If the comparison does not result in a match, the container is applying scaling to the object. The object must then decide whether it should continue the in-place editing in the scale/zoom mode or deactivate.
