I want to make a PyQt5 GUI software, which involves to the operation of the directory tree, I want it to be able to drag and drop within a directory tree, to change the location of the document. I use the QTreeView and QFileSystemModel realize this function, but found it can't drag and drop.
Code:

 
The class FileTreeView (QTreeView) : 
Def __init__ (self, parent=None) : 
Super () __init__ (parent) 
Self. SetDragEnabled (True) 
Self. SetAcceptDrops (True) 
Self. SetDragDropMode (QAbstractItemView. DragDrop) 
Self. SetDefaultDropAction (Qt. CopyAction) 

And then use this class behind:

 
The self. The UI. File_view=FileTreeView (self. UI. LayoutWidget) 
The self. The UI. File_view. SetObjectName (" file_view ") 
The self. The UI. The verticalLayout. AddWidget (self. UI. File_view) 

And then set the model:

 
The self. The model=QFileSystemModel (self) 
The self. The UI. File_view. SetModel (self. Model) 

But found to drag and drop.
Because can't screenshots when drag and drop, so can't let you see the effect of failure, as a general description is a red symbol is prohibited.
Does anyone know why?
