Drag-and-drop of files from file browser to a jupyterlab notebook widget

[Christian Schafmeister]

Is there any way to drag-and-drop files from the file browser to a jupyterlab notebook widget?  Specifically - the FileUpload widget?

1. I can't drag and drop from the Jupyterlab file browser to the FileUpload widget - I find that surprising.

2. I can't drag and drop from the system file browser (Finder on macOS) to a FileUpload widget.

3. I can click on the FileUpload widget and then navigate to any folder and select a file - is that the only thing I can do?

Is there any way that the files in the Jupyterlab file browser can be connected to a jupyter notebook widget?

I could type the name of a file into a TextInput widget but is that it?
