interface is implemented by container applications and used by object
applications to negotiate border space on the document or frame window. The container
provides a RECT
structure in which the object can place toolbars and other similar controls,
determines if tools can in fact be installed around the object's window frame,
allocates space for the border, and establishes a communication channel between
the object and each frame and document window.
The document window may not exist in all applications. When this is the case, IOleInPlaceSite::GetWindowContext
returns NULL for IOleInPlaceUIWindow
When to Implement
You must implement this interface if you are writing a container application
that will participate in-place activation.
When to Use
Used by object applications to negotiate border space on the document or frame
window when one of its objects is being activated or to renegotiate border
space if the size of the object changes.
