Update the Rectangle of a Newly Inserted Object

As a user-interface design decision in Container, the rectangle of a newly inserted object is updated to reflect its natural extent, as determined by the server. A container application can ignore the natural extent if, for example, you prefer to clip the object in the rectangle.

To update the rectangle of a newly inserted object to its natural extent

• Use ClassView to jump to CContainerView::OnInsertObject, just before the comment lines beginning with:

      // If item created from class list...
  

  insert this code:

      pItem->UpdateLink(); 
      pItem->UpdateFromServerExtent();
  

COleClientItem::UpdateLink is called so that if the server is fully open, Container has a visual representation of the newly created item, even though the item hasn’t been changed by the user yet.

To implement smart invalidation of the newly inserted item

• In the same OnInsertObject function, replace the following code:

      // TODO: reimplement selection as appropriate 
      // for your application
      m_pSelection = pItem;
      pDoc->UpdateAllViews(NULL);
  

  with this code:

      SetSelection(pItem);
      pItem->InvalidateItem();
