Hi lists, Just reporting in the conclusion of the grant work: "Rework handling of multi-layer, mixed-format datasets". You can read more about the motivation behind this work at https://github.com/qgis/QGIS-Enhancement-Proposals/issues/216
While the work was partly motivated as an opportunity to clean up some older parts of the QGIS codebase which were fragile and had low test coverage, it has also resulted in many improvements and polish in the QGIS user interface. Specifically: - There's a much improved dialog shown when a user has to pick from multiple layers from a dataset dropped onto QGIS. The dialog will populate in a background thread, avoiding the UI hangs older QGIS versions experience when scanning for layers in large files. The dialog shows a unified view of all layers in the dataset, regardless of whether they are vector, raster or mesh layers. There's also a new "filter" widget allowing users to quickly find matching layers in larger datasets. - The browser view of files and file-based datasources has been reworked. You'll no longer see duplicate entries for the same files when these files can be read as either raster/vector/mesh layers (e.g. for netcdf files, geopdf files and other mixed-format types). A lot of consistency has been added to the right click actions you see when interacting with file based items, with many bugs fixed along the way. Under the hood, we've now got a flexible API for querying sublayers of a dataset which can be easily extended to new providers so that they automatically participate in the unified sublayers dialog and browser items. It's all protected by a huge number of new unit tests, the majority of which cover critical functionality which was previously not being tested. Thanks for funding this work!
