[GIS] Zooming to selected feature using PyQGIS

Question

I want to create a function that selects a feature and zooms to it (similar in QGIS). Therefore there is following function:

QgsMapLayerRegistry.instance().addMapLayer(self.vlayer)

def zoomTo(self):
    layer = self.vlayer
    atable = self.ui.table
        
    selectList=[]
    for i in atable.selectionModel().selectedRows():
        ID = atable.item(i.row(),0).text()
        selectList.append(int(ID))
  
    layer.setSelectedFeatures(selectList)

The selected features are highlighted on the map. But I have no idea how to make a "zoom" to the selected features or some kind of focus them in the middle of the map.

Answer 1

You need to set the extents of the map canvas to the extents of the selections:

box = layer.boundingBoxOfSelected()
iface.mapCanvas().setExtent(box)
iface.mapCanvas().refresh()
