A small helper class which blocks an asynchronous operation (e.g. a KIO request)

so that it can be used in a synchronous environment.

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