To write QGIS C++ plugin see : http://download.osgeo.org/qgis/doc/manual/qgis-1.1.0_coding-compilation_guide_en.pdf (2.2 Programming a QGIS C++ Plugin in four steps) And you can find some C++ plugin examples here: https://github.com/qgis/QGIS-Code-Examples and https://github.com/qgis/QGIS-Code-Examples/tree/master/4_adding_rasters_to_canvas

How are you initializing it? Or do you just declare it and add a raster layer directly? Because from that link, I see the addRasterLayer method is a pure virtual function and QgisInterface is abstract class. I want to add this layer into a QgsMapCanvas, how should I do that? Also, is it possible for you to test my code before to see if it works on your system?
