 Save the code above as <tt>marble_control.cpp</tt> and compile it:
-<code>

 If things go fine, execute <tt>./marble_control</tt> and you end up with a map application that displays our globe with a zoom slider below:

 We'd like to add other widgets to our Marble window: A '''zoom slider''' and a '''label''' that shows the current mouse position in '''geodetic''' coordinates: ''longitude'' and ''latitude''.
-In order to achieve this we need to create a vertical layout. Once done we add the slider and the label that we created to the layout. Also we zoom the globe to the slider's default value using the [http://api.kde.org/4.x-api/kdeedu-apidocs/marble/html/classMarble_1_1MarbleWidget.html#d49d8ab0be0721c579bb511bdda45829 MarbleWidget::zoomView(int)] method.

 We want to center our globe onto South America. So we create a new [http://api.kde.org/4.x-api/kdeedu-apidocs/marble/html/classMarble_1_1GeoDataCoordinates.html GeoDataCoordinates] object that takes the longitude and the latitude as a parameter and we call [http://api.kde.org/4.x-api/kdeedu-apidocs/marble/html/classMarble_1_1MarbleWidget.html#7cda9942ead26d60c89a7b54a073a2fd MarbleWidget::centerOn].
