If you want to achieve drag from the program to the desktop, create a file on the surface of the table (don't know if this meaning), you can use the following method,
Create a temporary file, the file is you want to drag to create a file on the desktop, and then set a QMimeData QDrag, type of text/uri - list, value is the path of the temporary file, and then the operating system in the treatment of the drop automatically realize file copying,
The following code:

 
QMimeData * mimeData=https://bbs.csdn.net/topics/new QMimeData; 
MimeData - & gt; SetData (" text/uri - list ", "file:///D:/abc/test"); 

Drag QDrag *=new QDrag; 
Drag - & gt; SetMimeData (mimeData); 
Drag - & gt; SetPixmap (XXX); 
Drag - & gt; The exec (Qt: : CopyAction | Qt: : MoveAction, Qt: : CopyAction);
