Drag and Drop library error ("NameError: Name draggable not found")

[Clavier]

Hi, 

I encountered an error while using the drag and drop library. I tested the DND test example (https://github.com/pyjs/pyjs/tree/master/examples/dnd), and the same error was raised:

Traceback (most recent call last):

NameError: Name draggable not found

This error appears only in pyjd, but not in a webbrower version. Is the drag and drop library not matured enough? Please let me know if you have an idea about how to fix the error.

Thanks in advance.

pyjd for win is setup here:

https://github.com/pyjs/pyjs/blob/master/pyjs/runners/mshtml.py#L407

...and here:

https://github.com/pyjs/pyjs/blob/master/pyjs/runners/mshtml.py#L270

...and is mostly just sets up a pass through to a comtypes library object (as evidenced by traceback) . The problem seems the target object (IWebBrowser2?) does not implement draggable, or, at the very least, does not have said attribute.

You'd need to review the appropriate interfaces in MS docs, or explore the API from an interactive session (if possible), for possible workarounds/alternatives.
