Developing MVC academic application with Qt 4.8

Hi there, im a CS student and im new with Qt, i’ve to develop a chart visualizer application using g++ and Qt 4.8 (not 5). The target is to use the object oriented properties to plot many kinds of charts (histogram, pie, lines, e.g .) and load/store/modify datas using xml. I’m trying to understand which class hierarchy to use but i’d like to use MVC model but i cant understand/find what to do. For plotting i can choose if develop myself an appropriate class drawing “by pixels” or use some Qt’s classes like Plotter widget. But i’d like to understand which class plays MVC roles: – Model: i fetch datas via xml using Qt’s classes – View: Plotter or something similar – Control/delegate: for handling the view’s data? I’m supposed to keep them separately to follow mvc model…is it correct or im missing something?! thanks Enrico
