+ so that it can be used in a synchronous environment.

+ Example:
+
+ ...
+
+ Synchronizer mSynchronizer;
+
+ ...
+
+ job = KIO::file_copy( url, file, -1, true );
+ connect( job, SIGNAL( result( KIO::Job * ) ),
+ SLOT( slotResult( KIO::Job * ) ) );
+
+ mSynchronizer.start(); // will block here until the slot was called
+ ...
+
+
+ void slotResult( KIO::Job* )
+ {
+ mSynchronizer.stop();
+ }
