0001 See https://techbase.kde.org/Marble/MarbleMarbleWidget for the online
0002 version of this example.

0004 We'd like to display a small weather map. So we need to modify the map. And we
0005 need to turn on the satellite view, enable the clouds and enable the country
0006 border lines.
0007 Again MarbleWidget provides a convenient way to make these changes to the
0008 overall look and feel of the map.
0009 By default Marble shows a few info boxes: Overview Map, Compass and ScaleBar.
0010 But the size for the widget is very limited. Therefore we want to shrink the
0011 compass. And we want to get rid of all the clutter, so we turn off the Overview
0012 Map and the ScaleBar. In the source code the class AbstractFloatItem is used to
0013 display all kinds of Info Boxes. All the Info Boxes are derived from the
0014 AbstractFloatItem class. Now we get a list of all the float items that are
0015 known to MarbleWidget and we go through it. Once we reach the float item which
0016 has got the name id "compass" we make all the changes we want to it (this has
0017 been simplified in Marble 0.11.0 where you can access AbstractFloatItems
0018 directly via their nameId)
