[digiKam-users] Copy file path and name to clipboard from thumbs view

I just tested using Notepad++ and The Gimp. Copy / Paste does not do 
anything. I tried using Ctrl+C, Ctrl+Ins and the "Copy" option in the 
thumbnail's contextual menu, same results.

Notepad++ reacts as if there was no text to paste :

and Gimp does the same :

The Gimp's message seems a little more informative, but unfortunately 
the message is the same if the clipboard is empty or if it contains no 
image data.

Drag & Drop works fine both with Notepad++ and with The Gimp.

Gilles, I was a little surprised that you expected Copy to copy the name 
of the image instead of it's contents. From your answer, I later 
realized that you expected Copy to work on both.

Using Nirsoft's InsideClipboard tool, I found that DK did indeed put 
something in the clipboard, but that Notepad++ and The Gimp could not 
understand it. So I checked copying from different tools as a source (an 
image viewer, Windows Explorer and so on). The image viewer I checked 
copies the image contents, and works only with The Gimp. Windows 
Explorer and another file manager don't work with Notepad++ or with The 
Gimp, just like DigiKam. I could not find any tool which would copy both 
the contents and the path in such a way that it worked with Notepad++ 
and The Gimp. OTOH, copying from DK towards Windows Explorer or another 
file manager works.

My conclusion is that the Windows clipboard is much less tolerant than 
the Linux clipboard, the Windows clipboard contains either a file 
(actually not the file itself, but data allowing to identify it), text, 
image (or probably music and so on) but not several types of data at 
once. So that copying from DK can either work with a file manager, a 
text editor or a graphics software but not with all at once. Currently, 
DK places file data. I have no idea why software aren't as smart with 
the clipboard as with Drag & Drop. Maybe some other text editor is smart 
enough to parse the clipboard and fetch the file path from what DK 
places there?

Note that DK does not always copy file data to the clipboard. If you 
edit an image and select some part of it, DK copies image data instead, 
which makes perfect sense IMO, so that you can then paste to The Gimp.

InsideClipboard can save a digest of the clipboard contents. I you find 
it useful, I can post digests taken in different situations.

>> Hey Robert ,
>> I was interested in seeing how people might respond to this question. I was surprised at Gilles's answer as I've never seen an option to copy an image file path in my older v7.3.0,  wondering if it was a feature added in a newer build. I'm running it in Windows 7 and that 'Copy' menu option does just copy the image as would be expected. When I want to get the actual path to a file, I right-click a thumbnail and select the 'Open In File Manager' menu option which brings up Windows Explorer at the folder that contains the file. I would think Linux would bring up whatever file manager you have installed.
