- Jack,
-
- About one year ago, I had a long discussion in a restricted conf with
- J.Mackraz (sp?). It was 2.0 beta time, and appicons/menus/... was one
- of the topics.
-
- I complained that the Amiga system seemed to get all the new stuff in
- the wrong places: in this case, icon drag/drop being a Workbench feature
- rather than an Intuition feature. Another case was boopsi starting out
- as an object oriented USER INTERFACE and being within intuition rather
- then a basic system feature that new subsystems of any kind could be
- built upon.
-
- If I recall well, J.M. mantained that it would have been very hard, if
- not impossible, to provide secure arbitration of layers on public screens
- when multiple applications were involved in a drag-drop (which would
- typically imply dragging a BOB over windows).
-
- It seemed at that time that the basic stuff is indeed in place (layer
- locking IS there), but some othe parts of the system which would have
- been involved needed some major overhaul. This was the case with Workbench,
- which seemed to mess around with its screen a lot.
-
- If J.M. or any other CBM person can confirm or deny this (I have memory
- leaks...), please correct me.
-
- Now, we know that the Wbench HAS been re-written, and things may be
- different now. I also recall, a while back I read some more info about
- a forthcoming pair of boopsi classes for draggable objs and dropboxes,
- but I can't dig that out at this moment. Anyone has more on that?
-
- Andy.
