Using Qt 4.4.3

I have a Qtablewidget which is in a .ui file, and is used to make a list of files. In designer I have enabled drop to this widget, however I am not totally sure what signal is triggered on drop, nor how to get the mime information. My goal is to be able to drag a file from outside of my program on to the QTableWidget which is defined in the .ui file, and have the mime data returned upon that event, so I can do something with it.

I have looked do far in the forums and on the "Drop Site Example" which seems to be the closest thing to what I need. However, none of the examples that I have found show using drag and drop into a widget that was placed with designer (the interface is getting kindof complex, so being able to keep it all within the .ui file helps a lot).

How can I enable the QTableWidget within my .ui file to work with a drop from an external source?
