Dear all, I would like to display only say the 50 most important features of a layer in a QGIS project when I zoom out and in. Almost all features have an attribute qrank starting at NULL or 1, and the larger qrank is, the more "important" the object is. Here is a demo of the web app https://castle-map.infs.ch/
You can set a filter by right-clicking on the layer, e.g. as follows: SELECT * FROM “castles_etc_ranked_osm_2025” ORDER BY qrank DESC LIMIT 50; The problem is that QGIS only applies this filter (and SQL) once (when setting up the filter). However, I want QGIS to update this filter and reapply it every time someone's zooming or panning. I have looked in vain at the options for “Update Layer with notify” in the layer menu in the “Display” tab. I also tried it with a view and the file manager, but without success. 1. Can QGIS be configured this way? E.g. with Dynamic Provider Filter Plugin? 2. I think a small Python script (QGIS Python Console) could be another solutions. But which signals would I need to intercept?
