/**
|
||
|
|
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, SIGNAL( result( KIO::Job * ) ),
|
||
|
|
SLOT( slotResult( KIO::Job * ) ) );
|
||
|
|
|
||
|
|
mSynchronizer.start(); // will block here until the slot was called
|
||
|
|
...
|
||
|
|
|
||
|
|
|
||
|
|
void slotResult( KIO::Job* )
|
||
|
|
{
|
||
|
|
mSynchronizer.stop();
|
||
|
|
}
|
