+Qt supports native drag and drop on all platforms via an extensible
+MIME-based system that enables applications to send data to each other in the
+most appropriate formats.
+
+Drag and drop can also be implemented for internal use by applications.
+
+
+Documentation for these examples can be found via the Examples
+link in the main Qt documentation.
