Status: RESOLVED EXPIRED

(Core :: DOM: Copy & Paste and Drag & Drop, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007

Mozilla drag and drop doesn't accept the UniformResourceLocator (CFSTR_SHELLURL)
drag and drop type under windows (at least windows XP). It does accept unicode
text which happens to be a url, and favorites files which contain urls. I've
attached a test C# application, with source, which demonstrates this: click and
drag from the "URL alone" label to drag & drop a UniformResourceLocator alone,
and click and drag the "URL with unicode text" label to also have the unicode
text filled in. Mozilla, however, does *generate* the UniformResourceLocator
type (you can verify this by dropping a url from mozilla on top of ClipSpy, at
http://home.inreach.com/mdunn/code/ClipSpy/clipspy.html). For the moment, I have
a workaround in our program that puts unicode text in with the url along with
the proper UniformResourceLocator, but that may have to change once we start
allowing people to drag & drop text with links as well (which would more or less
cripple people trying to use mozilla with our program).

Reproducible: Always

Steps to Reproduce:
1. run the DnD URL text.exe program I attached
2. click down on the "URL alone" label, drag, and release over a mozilla content
window.

Actual Results:  
The cursor did turn to the D&D "copy" icon, but nothing happened on release.

Expected Results:  
Gone to the dragged web page. To see that result, click down and drag from the
"URL with unicode text" label.

Oh, I forgot to mention: I did try to debug this a bit on the mozilla end. It
seems that nsClipboard::GetFormat, in widget/src/windows/nsClipboard.cpp tries
to translate text/x-moz-url to CF_UNICODE_TEXT, where it seems perhaps it ought
to use CFSTR_SHELLURL. Bug 71786, comment 16 mentions this change, but the later
discussion seems to imply that other things would also have to be changed for
this to work.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
