best practice to build a 2D vectorial map viewer with custom objects above.

[corrado1972]

Hello you all,
I'm delphi developer that decided to switching to QT. I'm using QT4.6.

I must create a customer application that load a 2D vectorial map and into the map shows some buildings with relevant data for the customers. This app doesnt requires 3D features.

I'm starting reading the QT documentation, in particular The Graphics View Framework.

I'm asking you which is the best practice to develop an application like that i described: I'm thinking that I have to load svg map into a scene, then I have to design customer buildings as widgets objects and put them into the scene at specific coordinates.
Is it the right way?

Please suggest me the right way to do this or, if you know any opensource project that do this job, give me the link so i can study source code.

thanks
