133963 - Scroll window properly when dragging items to window boundary

Status: NEW

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

Description

[The Cunctator]

Build 2002031005

To reproduce:
1. open Bookmarks > Manage Bookmarks...
2. Make sure you have more bookmarks than can be seen in the window (so that
scrollbar appears)
3. Select a bookmark and drag to top/bottom edge of bookmarks (e.g. select
bottom-most bookmark and drag towards top of list)

Expected behavior:
(as in Finder)
When the bookmark ghost touches the vertical edge of the Manage Bookmarks
window, the window should start scrolling continuously. The window will scroll
as long as any part of the bookmark ghost touches the vertical edge and the
cursor hotpoint is within the window. The rate of scrolling is fastest when the
cursor hotpoint is directly within the vertical edge.


Actual behavior:
1. The Manage Bookmarks window only scrolls if the cursor is being moved. This
is a major usability bug.

2. On top, the window scrolls when the cursor is within the Name/Location bar as
well as the window.

3. There does not seem to be any scrolling acceleration/deceleration
functionality, but that's difficult to test, because of actual behavior #1.

Confirmed using FizzillaCFM/2002041712 (RC1). This occurs in any Mozilla window
where an item is dragged to the window border to effect scrolling, such as
dragging an e-mail message to a mail folder visible only after scrolling of the
folder pane.

we need the event for trees, textareas and iframes. this is also expected
behavior on windows. <bug has been hijacked.>

I do not see either of these two behaviors.  When the cursor is on the boundary 
but not moving, scrolling continues; when the cursor is moved into the column 
headers, scrolling stops.

This does appear to be the case.
