           Summary: Ability to drag&drop images from digikam to
                    chrome/google+
           Product: digikam
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR

Version:           unspecified (using KDE 4.7.0)
OS:                Linux

Hello,

I miss an ability to drag & drop photos from digikam window to chrome window to
upload to server (i.e. google+). I don't know the chrome version this is
possible from, but in ver.11 it is. It also is possible drag & drop from
gwenview window, but it is too complicated to make some filtered photo group in
digikam, tag it with some temp tag, then open gwenview and show pics with the
tag and then d&d to the chrome.

Is this feature possible?

Reproducible: Always

Steps to Reproduce:
drag and drop pics from digikam to chrome window


Expected Results:  
possibility of drag & drop pics from digikam to chrome window

Fully reproducible here.

I need to use gwenview instead. Drag and drop work fine.

Note: With Dolphin, it doesn't work. digiKam and Dolphin use same component for
icon-view, which include D&D implementation if i'm not too wrong.

It can be something to improve in KDELibs. Marcel, i'm not sure. Your viewpoint
?

We have our own d&d implemtation in ddragobjects.cpp. We have some internal
mimetypes, but also add the interoperable mime data (file URLs) through the
kdelibs method KUrl::List::populateMimeData. This is why you can drag from
digikam to e.g. dolphin.

I was searching for "QMimeData" in gwenview's source and did not find anything
special except for using the populdateMimeData method as well.

There is an easy way to debug dropped mime data. Add the two lines to
dragdrop/imagedragdrop.cpp, 598:

Qt::DropAction ImageDragDropHandler::accepts(const QDropEvent* e, const
QModelIndex& /*dropIndex*/)
{
    kDebug() << "Dropped mimetypes:" << e->mimeData()->formats();
    return false;
    if (albumModel() && !albumModel()->currentAlbum())

Then drop from dolphin, chrome, gwenview, and digikam to the digikam icon view.
There should be a line output with the offered mimetypes each time. Then we can
see if gwenview adds some magic to the drag.

Certainly not wanting to make this a "me too" comment fest, just noticed not
much chatter on this issue.  I'm not in a position to alter and compile the
above, but can confirm that I cannot drag and drop files from Dolphin to Chrome
(i.e. GMail attachments).  Works ok with Firefox or with Chrome and any other
file browser (Krusader, or a Gnome file browser).

I'm GMail + Chromium user, and D&D work fine here with digiKam to attach photo
to mail.

I made a test with the "dropsite" Qt-example application. Dnd from gwenview
results in these mime-types:

text/uri-list
text/x-moz-url
text/plain
UTF8_STRING
STRING
TEXT
COMPOUND_TEXT
application/x-qiconlist

whereas Dnd from digikam results in

digikam/item-ids
digikam/digikamalbums
digikam/album-ids
digikam/image-ids-long
text/uri-list
text/x-moz-url
text/plain
UTF8_STRING
STRING
TEXT
COMPOUND_TEXT

The additional mime-types (digikam/*) should not trigger different behaviour
IMHO.

A quick test in firefox shows that DND is working from gwenview and from
digikam. Seems to be a bug on the chrome-side of things... Perhaps it gets
confused by the  digikam-specific mime-types.

Yes, it's sound like a bug in Chrome. We respect DND standard provided by Qt.
Chreme must be able to ignore digikam* type mime used for intenal DND purpose
and use standarized one that we provide.

Please report this problem to Chrome bugzilla. Thanks in advance.
