A Demoapplication


QMapControl is a Qt/Qtopia widget which enables your (mobile) applications to use map data. Simply add the widget to your application, have a look at the API and start developing a fancy geospatial (mobile) application.

With QMapControl you can use different map providers, like OpenStreetMap or several WMS-Server. Then you can modify the view of your QMapControl, writing a location based application when having a GPS receiver or just browse the maps. It is possible to have more than one layers, so you can mix maps from different servers. To enrich the maps you can draw your own object to coordinates.
