-Marble uses so-called runners to calculate routes, do reverse geocoding, parse files and search for placemarks (cities, addresses, points of interest, ...). This tutorial shows how to use the <tt>[http://api.kde.org/4.x-api/kdeedu-apidocs/marble/html/classMarble_1_1MarbleRunnerManager.html MarbleRunnerManager]</tt> class to open a .kml (or .gpx, .osm, ...) file and display it into the Marble Widget.

-If things go fine, execute <tt>./my_marble some-file.kml</tt> and you get a Marble Widget which displays your KML file. For example, download and unpack [[File:Bucharest.kml.gz]] (a [http://api.kde.org/4.x-api/kdeedu-apidocs/marble/html/classMarble_1_1GeoDataLinearRing.html LinearRing] representing Bucharest's city boundaries), place it in the same folder as your <tt>my_marble.cpp</tt> file and run <tt>./my_marble bucharest.kml</tt>.
