Drag and drop midi file to host

Hi there, what I want to do is exactly the same with this topic http://www.juce.com/forum/topic/drag-and-drop-function . But that's a pretty old topic and PlatformUtilities class has been removed since Jun 29, 2011. I checked the commit 94a0bf1af15baf015f650bff0f24c52f8868affe where PlatformUtilities was removed and I found some functions were moved to DynamicLibrary and WindowsRegistry,  but I could not find where PlatformUtilities::canDropFilesAtMousePosition() and dropFilesAtMousePosition()  have gone. Can anyone help?

See DragAndDropContainer::performExternalDragDropOfFiles

Thanks a lot. It is very handy to use.
