Hi Daniel
Thanks for your help. I tried nasa server within my app without success, rlayer is still invalid. I also tried within the QGis app, the server returned "this server no longer provide full WMS services!"... I also notice that my app starts immediatly, I'm not sure wether it should take some seconds or not.... Anyway, I added some paths in my app (defaultsvg and plugins), and now my wms server is "Valid'. But there's still nothing displayed in my map. Here's the current code regardings layers : QgsMapLayerRegistry::instance()->addMapLayer(rlayer); QList <QgsMapCanvasLayer> myLayerSet; myLayerSet.append(QgsMapCanvasLayer(rlayer, TRUE)); mapCanvas->setLayerSet(myLayerSet); mapCanvas->zoomScale(1/10000); mapCanvas->centerOn(5.7, 45.2); mapCanvas->update(); mapCanvas->refresh(); ________________________________ De : Daniel <[email protected]> À : "[email protected]" <[email protected]> Cc : "[email protected]" <[email protected]> Envoyé le : Dimanche 6 octobre 2013 21h06 Objet : Re: [Qgis-developer] New QGis project, application : version is empty and wms layer invalid I don't know if you should receive "2.0" as output of applicationVersion() method. It's because setApplicationVersion() and setApplicationName() are called from src/core/main.cpp (QGIS code). The class QgsApplication don't call setter methods, so I don't know what are the supposed behavior when I call these methods. It works for me QString uri= "url=http://wms.jpl.nasa.gov/wms.cgi&crs=EPSG:4326&format=image/jpeg&layers=global_mosaic&styles=pseudo";; qDebug() << "uri" << uri; QgsRasterLayer *rlayer = new QgsRasterLayer(uri, "layer_name", "wms", false); qDebug() << rlayer->isValid(); Hope it helps you On Sun, Oct 6, 2013 at 2:32 PM, [email protected] <[email protected]> wrote: > >Hi > > >This is my first attemp with QGIS.
