QSignalAggregator

Barrier for Qt signals.

Usage

QSimpleSignalAggregator *aggregator = new QSimpleSignalAggregator(this);
QObject::connect(aggregator, SIGNAL(done()), this, SLOT(allSignalsInvoked()));
aggregator->aggregate(foo, SIGNAL(done()));
aggregator->aggregate(bar, SIGNAL(done()));

As soon as foo::done() and bar::done() are emitted, aggregator::done() is emitted.

API

aggregate(sender, signal)

Add the sender's specified signal to the list of monitored signals.

gate(sender, signal)

Emit the specified object's signal when all monitored signals have been witnessed (rather than the default done() from the QSignalAggregator object).

reset()

Forget about witnessed signals and start monitoring for all aggregated signals again.
