+ \class QWindowsInternalMimeDataBase
+ \brief Base for implementations of QInternalMimeData using a IDataObject COM object.
+
+ In clipboard handling and Drag and drop, static instances
+ of QInternalMimeData implementations are kept and passed to the client.
+
+ QInternalMimeData provides virtuals that query the formats and retrieve
+ mime data on demand when the client invokes functions like QMimeData::hasHtml(),
+ QMimeData::html() on the instance returned. Otherwise, expensive
+ construction of a new QMimeData object containing all possible
+ formats would have to be done in each call to mimeData().
+
+ The base class introduces new virtuals to obtain and release
+ the instances IDataObject from the clipboard or Drag and Drop and
+ does conversion using QWindowsMime classes.
