void	reportDone(QtTaskTree::DoneResult result)

Detailed Description

The custom Adapter type of the QCustomTask<Task, Adapter, Deleter> template is expected to have the following form, when adapting Worker task:

 class WorkerTaskAdapter
 {
 public:
     void operator()(Worker *task, QTaskInterface *iface) { ... }
 };

 using WorkerTask = QCustomTask<Worker, WorkerTaskAdapter>;

Member Function Documentation

void QTaskInterface::reportDone(QtTaskTree::DoneResult result)

This method should be called when the task adapted via custom adapter is finished, passing the result of the task execution.

Assuming the Worker emits a finished(bool) signal, the adapter may look like:

 class WorkerTaskAdapter
 {
 public:
     void operator()(Worker *task, QTaskInterface *iface) {
         connect(task, &Worker::finished, iface, [iface](bool success) {
             iface->reportDone(QtTaskTree::toDoneResult(success));
         });
         task->execute();
     }
 };

 using WorkerTask = QCustomTask<Worker, WorkerTaskAdapter>;
