The problem is this: I like having my Browser remember its place, more
or less, when things disappear. Say I have two Browsers open. I want to move a class between system categories so I click on my victim and drag it to the other Browser's system category list. I drop it there, and the move takes place. But I lose my place in the source Browser. I want the source Browser to select the class either immediately before the removed class or immediately after. Not fussed which. Now the process starts in #dragFromClassList: in the source Browser and ends in #dropOnSystemCategories:at: in the target Browser. Calling #selectClassNamed: in the source Browser in #dragFromClassList: is premature because the drag hasn't happened yet, and things get weird. But how can I tell the source Browser "ok, the drag's done; select the class next to where the moved class was" ? frank |
I hate to ask, but could the old selection _index_ have help here?
Besides that, I don't know whether something could be done in TransferMorph>>#justDroppedInto:event:. TransferMorph knows his "source" is that the source browser? If so, maybe it could be told to do some kind of post-op?

For once, yes, the no-semantic-info-just-ui-info index would have been
handy here :) OK, so a TransferMorph is that blue labelled rectangle that appears during the drag part of the operation? I'll take a look at that and see if I can join the post-drag dots there.
