I think you are blurring two meanings of "copy", and probably everyone was expecting within qgis. Also, you say "instances" and there's a difference between two project windows in one process and two processes. (I don't know if qgis can operate two project windows.) I suspect that "copy from one QGIS instance to another" is an X11 (or perhaps other window system) operation. As I understand it, the X11 clipboard is simply text. I have never contemplated copying features via the X11 instance, or expected that features could be pasted between instances. You might try pasting into a text editor and understand the encoding. Probably WKT2 or something like that. When you copy/paste within QGIS, I would expect what is copied to be richer, with columns having names. I see this as the normal approach. You might be able to understand this by reading the code, and seeing what the copy operation does in terms of storing a feature within qgis, and how that feature is mapped to text for the clipboard, and similarly for paste. If you are transferring features between datasets, I'd recommend having both datasets in the same project, at least temporarily, to avoid using the X11 clipboard. _______________________________________________ QGIS-User mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
