Signals

void done(QtTaskTree::DoneResult result)

Detailed Description

QBarrier waits for subsequent calls to advance() to reach the barrier's limit (1 by default). It finishes with DoneResult::Success.

It's often used in QTaskTree recipes to hold the execution of subsequent sequential tasks until some other running task delivers some data which are needed to setup the subsequent tasks.

[private signal] void QBarrier::done(QtTaskTree::DoneResult result)

Note: This is a private signal. It can be used in signal connections but cannot be emitted by the user.
