GIS design pattern

[olosie]

I need create simple GIS software (show and manipulate map). Is there any design pattern for this?
my question is how should this be done?
Graphics View Framework is the right way?

Hi,

I am looking around the web for quite a while to find some examples how to use QGraphics in a simple GIS application. None of the Qt apps I know use this approach afaik (maybe I am not up-to-date): QMapControl, Merkaartor, QGis ... . If you are using Qt GPL it might be interesting to learn what you are planning to do.
