[QGIS-Developer] PyQGIS zoom to layer not working

[Frank Broniewski]

Hi,
I am writing a plugin, in which I am loading a bunch of layers, and I want to zoom on one of them. Layers are loaded through an action (click).

def load_layer(self):

        self.project.addMapLayers(
            [
                self.addresses_layer.layer,
                self.adminunits_layer.layer,
                self.georecord_layer,
            ],
            addToLegend=False,
        )
        self.project.addMapLayers(
            [
                self.geolocation_point_layer.layer,
                self.geolocation_line_layer.layer,
                self.geolocation_poly_layer.layer,
                self.ortho_layer
            ]
        )
        self.iface.mapCanvas().setExtent(self.georecord_layer.layer.extent())
        self.iface.mapCanvas().refresh()

but unfortunately, that does not work as expected. QGIS zooms just on the ortho_layer in the end. I have the suspicion, that the extent I set, gets overwritten by another layer that loads in in a later stage. Layers are from a PostGIS, and the ortho_layer is a WMS layer.

I tried googleing, mapCanvas().waitWhileRendering() and whatnot, it just will not zoom. I am completely clueless now, so any hints are greatly appreciated.

This is on OSGeo4W, QGIS 3.28 and Python , for explanation, the .layer attribute is the actual QGIS layer …

Many thanks,
Frank
