<span lang="EN-US">I’d like to develop a standalone application for air pollution modeling based on pyqgis. I installed QGIs version 2.2 on windows 7 64bits from osgeo installer and my development platform is Eclispe/pydev.</span></p>
<p class="MsoNormal"><span lang="EN-US">As a first step, I’m trying to load a shapefile and plot it on a qgsmapcanvas (see attached python code) : the shapefile is properly loaded but I can see it plotted only after minimizing the window and restoring it. I have tried to add repaint(), refresh() calls on the qgsmapcanvas or the window without any success. I must surely miss something simple and would appreciate some help if possible.</span></p>
<p class="MsoNormal"><span lang="EN-US">Thank you in advanced and best regards,</span></p><p class="MsoNormal"><span lang="EN-US"> </span></p><p class="MsoNormal"><span style>Sylvie</span></p><p class="MsoNormal"> </p></div>
