May-be you’d better show first the window, load the layer and refresh the canvas NOT the window

I installed QGIs version 2.2 on windows 7 64bits from osgeo installer and my development platform is Eclispe/pydev. 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. Thank you in advanced and best regards, Sylvie
