[Jsynthlib-devel] Fixing drag-n-drop

[Joe E. <jo...@em...>]

I noticed that drag-n-drop is enabled for the JTables in
AbstractLibraryFrame. However, it seems to be fairly broken.

Specifically:
1 - I wasn't able to drag from one library to another
2 - If I start to drag a patch and then place it back where I picked it
up from.... and *then* double-click anywhere in the table, the patch
that I had started to drag is pasted to the end of the library.
3 - Dragging a patch from one row in a library to another row fails to
overwrite the target row... *and* a double-click in the table pastes a
copy to the end of the table (like in item 2).

These all seem like broken behaviors to me. The correct behaviors, in my
opinion, would be:
2 - Draggin a patch and then placing it back where it came from should
remove the patch from the clipboard entirely. Also, double-clicking a
patch should never cause a paste.
3 - Dragging from one row to another should overwrite the target row.
Additionally, dragging from one row to a place off the end of the table
should create a new table entry with a copy.
1 - Dragging from one library/scene into another library/scene should
work, and the behaviors (in regards to replacement or appending of
patches) should be the same as the behavior mentioned for item 3.

Can anyone:
 1 - Confirm that I'm fairly correct in assessing the *current* behavior
of drag-n-drop in JSL, and
 2 - Offer their opinion on the bahvior changes I've proposed?
