Status: RESOLVED WORKSFORME

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

Description

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:0.9.5) Gecko/20011015
BuildID:    2001101516

Mozilla's drag+drop support is lacking and contains curious non-standard data.

Reproducible: Always
Steps to Reproduce:
1.Drag an image link from Mozilla to another app. Examine the data which was
dragged.

Actual Results:  Drag contains non-standard data like 'MZ ' 'utxt' and 'MOZm'.
The only standard data it contains is 'url'.

Expected Results:  This drag should contain three standard data types:

url: the url
plain text: the alt= if present
picture: the image

Non-standard data types shouldn't be there unless it's being dragged to another
Mozilla window (which is known by the host of a drag). 

A standard link drag ought to contain the title (styled text) and the url. A
standard text drag should contain styled text.

Explorer's (mac version) drag+drop support is superb and could be considered as
a model to build on.

Reporter, you need to be specific. What is the problem, and what should happen instead?

For instance, "I dragged a link to an image file to the desktop. It created a text file. It 
should have saved the image to the desktop."

reporter: if you're going to file a bug complaining about backend os api
calls/data formats please provide the equivalent formats you want and preferably
the api's we should be using.

There are some apps which will store all data dragged whether they are
reconigzed or not, like Drop Drawers. 

I was very specific. Perhaps you wanted a more concrete example?

Reporter, when I drag an image link from Mozilla to the Finder, a "Web Page
Location" file is created there that contains several resources, including MOZm
and MZ as you mentioned, as well as the .

However, you mentioned that you're dragging the link "to another app." Which
application, in particular, are you dragging to?

"another app" can be any app other than Mozilla, like the Finder or Drop
Drawers. It's not significant

Marking WorksForMe. Dragging an image link to the Finder results in a perfectly
usable Web Location file.
