Visualizing TopoGeometry objects (topology layers) is supported by core QGIS (PostgreSQL provider) since version 2.0.0 (2012) --strk; ___ QGIS-Developer mailing list QGIS-Developer@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer

It's stable and it's maintained (by me). No other QGIS plugins that I know of do this. It would be nice to get the code ported to the browser so to show a tree node containing all the topologies defined in a database and load that layer tree upon double-clicking on them. --strk; ___ QGIS-Developer mailing list QGIS-Developer@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer

[QGIS-Developer] Writing a driver plugin for a custom vector format
Hi QGIS community,I am currently working with a custom file format that contains geometry information. The format contains mixed geometry types and some style and meta information.The geometry is simple to map onto WKT and I have a parser for Python. I would like to integrate this into a QGIS plugin. It seems however that writing drivers for file formats is not really documented in the PyQGIS Developer Cookbook.My questions are therefore:Is it possible to introduce support for a custom file format through a plugin?At what level should I integrate this? It seems that most formats are handled through GDAL, which has its own plugin system. I would rather have it installable through the QGIS interfaceAre there any examples of similar formats (KML/GML) that are handled this way?Kind regards,Martijn Reening___ QGIS-Developer mailing list QGIS-Developer@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer

Re: [QGIS-Developer] Problem with LIKE/ILIKE expressions and line breaks
Hi Felix, I can confim the issue is a regression, as the expression works correctly with QGIS 3.20.3 and previous versions, while it doesn't since QGIS 3.22.0. It seems to me this issue is a side effect of the "migration" from QRegExp to QRegularExpression. I've submitted the PR https://github.com/qgis/QGIS/pull/50124 which fixes this issue, according to my tests. Regards.
