[Vm-dev] Extended Clipboard

Sat Mar 25 17:09:11 UTC 2023

The undefined symbol errors might just be something in the build
or makefiles. For the oscog build, I see console errors like
undefined symbol: sqPasteboardPutItemFlavordatalengthformatType.

The actual code is present in both the generated ./src file and
the ./platforms source. I'm probably overlooking something obvious.

And sqUnixXdnd.c was modified to handle multiple data types. When drag event with image type is come, sqUnixXdnd.c generate DropFileEvent with zero file count. Then, system will retrieve data from getSelectionData() with XdndSqueakSelection.
