Problem implementing runTaskWithProgressBar(te::ThreadPoolJobWithProgress& job)

[RolandMR]

You can’t call job.runJob() on the main thread, or your UI will not respond, as you are seeing. You need spawn a thread which calls job.runJob() in a loop.

Then runTaskWithProgressBar needs to wait until the thread is finished while pumping message loop.

Rough code to implement:

    void runTaskWithProgressBar (ThreadPoolJobWithProgress& t)
    {
        TaskRunner runner (t);

         while (runner.isThreadRunning())
             if (! MessageManager::getInstance()->runDispatchLoopUntil (10))
                 break;
    }

//==============================================================================
struct TaskRunner  : public Thread
{
    TaskRunner (ThreadPoolJobWithProgress& t) : Thread (t->getJobName()), task (*t)
    {
        startThread (4);
    }

    ~TaskRunner()
    {
        task.signalJobShouldExit();
        waitForThreadToExit (10000);
    }

    void run() override
    {
        while (! threadShouldExit())
            if (task.runJob() == ThreadPoolJob::jobHasFinished)
                break;
    }

    ThreadPoolJobWithProgress& task;
};

You’ll need to add whatever updates your UI.
