Retrieves a running object's current display size.
| DWORD dwDrawAspect,
||//Value indicating object aspect
| SIZEL *psizel
||//Pointer to storage of object size limit
[in] Describes the aspect of the object whose limit is to be retrieved; the
value is obtained from the enumeration DVASPECT
. The most common value for this method is DVASPECT_CONTENT, which specifies a
full rendering of the object within its container.
[out] Points to where the object's size is to be returned.
Extent information successfully returned.
Invalid value for dwAspect.
A container calls IOleObject::GetExtent
on a running object to retrieve its current display size. If the container
can accommodate that size, it will normally do so because the object, after all,
knows what size it should be better than the container does. A container
normally makes this call as part of initializing an object.
The display size returned by IOleObject::GetExtent
may differ from the size last set by IOleObject::SetExtent
because the latter method dictates the object's display space at the time the
method is called but does not necessarily change the object's native size, as
determined by its application.
Notes to Callers
Because a container can make this call only to a running object, the container
must instead call IViewObject2::GetExtent
if it wants to get the display size of a loaded object from its cache.
Notes to Implementors
Implementation consists of filling the sizel
structure with an object's height and width.
