[Vm-dev] [OpenSmalltalk/opensmalltalk-vm] sqUnixXdnd: Don't record SQDragLeave when XdndDrop is handled (#508)

[Vanessa Freudenberg]

Regarding code ownership - there currently is nobody specifically tending to the unix VM, or the X window display system. Most of the code is more than 15 years old, written by Ian Piumarta. Others and I contributed smaller parts over the years. That history got lost when switching from svn to git.

As for DND, at some point around 2007 it was working fully - you could drag pictures and rich text into Squeak (e.g. a paragraph from Wikipedia), and you could drag e.g. a morph out of Squeak into an office document (where it would appear as a bitmap image) or onto another Squeak (where it would appear as fully functioning object, all the scripts etc. were being serialized). The latter part might be why there are squeak-specific DnD events.

This was used for full interoperability inside of the Sugar OS on the OLPC laptop. E.g. you could drag a morph out of Etoys onto the Sugar Frame Clipboard, switch apps, and drag it into the other app. I used to be the maintainer of Squeak/Etoys for Sugar but haven’t touched it in years.
