<p class="MsoNormal"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Century Gothic",sans-serif">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.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Century Gothic",sans-serif">I tried googleing, mapCanvas().waitWhileRendering() and whatnot, it just will not zoom. I am completely clueless now, so any hints are greatly appreciated.<o:p></o:p></span></p>
