I am working in c++/qt4.8.5 with qgis api 2.8.2 For my application I had to load a raster in a mapcanvas, then with different action I had to add pint , line or polygon
Is there a simply way to do that, i have idée on how to start, for the moment i can load a raster, but now I had to add point but I wonderif I had to do that in the same way for adding vectorlayer to a mapcanvas without raster or there is something special.
