Detailed Description

Iterator class for looping over all entries in a Map type Config Node.

Typical usage:

Config config; display->save( config ); // Write display's data into config. for( Config::MapIterator iter = config.mapIterator(); iter.isValid(); iter.advance() ) { QString key = iter.currentKey(); Config child = iter.currentChild(); printf( "key %s has value %s.\n", qPrintable( key ), qPrintable( child.getValue().toString() )); }

Maps are stored in alphabetical order of their keys, and MapIterator uses this same order.
