Drag and drop files

Post by NotNull » Mon Oct 07, 2019 11:02 pm

The file manager I use the most - Q-Dir - does not function as a drop target when Everything is the source.
That is hardly Everything's fault; Q-Dir has trouble with multiple file managers (see screenshot)

Before reporting this issue with it's developer, I would like to know what API / method / ... Everything uses for dragging files.
That way it would be much easier to find a solution (at least that is what I hope).

Everything uses the IDropSource interface.

Everything implements its own IDropSource interface.
An IDataObject is created with CF_HDROP data of all the source files and folders.
DoDragDrop is called to begin the drag drop operation.
The default IDragSourceHelper is used to create the drag image.

(Does Q-Dir author actually make substantive changes [or even evolutionary changes] to [any of] his programs?
[I don't pay too much attention but] generally all I see are bug fixes, typically for things broken by Win10 "feature" updates.)

The author is very active, but his communication and the website are quite - let's call it - unstructured ( that's the moment when you realize that we, the Everything community, are terribly spoiled :))

Every week or so there is an update for Q-Dir. Most with a cryptic description "general improvements".
I posted quite a few suggestions and the ones that were honored (thus far) also ended up as "general improvements"
That is to say: the ones that I noticed; communication is minimal.


Semi on topic: I also suggested integrating Everything as he is experimenting with search functionality. Who knows what will happen in the future ...

And off topic: What happened to your Altap Salamander? :o

Nothing.
Except now free.
IOW (mostly) the same as it ever was.

Possible no future updates?
But here's hoping :-).

Doesn't change its' usefulness.

Ah, all right; I thought you were looking for a different file manager ...
