QObjects 被移动到 QThreads 后信号不再工作

基本上，标题...如果没有QThread(或者只是注释(，我得到以下结果：

LOG> Log working!
LOG> PRODUCER: sent resource address: 29980624
PRODUCER: sent resource address: 29980624
CONSUMER: received resource address: 29980624

29980624，或任何相关的内存位置。

但是，当取消评论时，只是

LOG> Log working!

主窗口.h

class MainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
public slots:
void slot_log(QString str);
signals:
void signal_log(QString str);
private:
void createConsumer( void );
void deleteConsumer( void );
void createProducer( void );
void deleteProducer( void );
void createConnections( void );
SingleConsumer *consumer;
QThread *thread_consumer;
SingleProducer *producer;
QThread *thread_producer;
};

主窗口.cpp

#include "mainwindow.h"
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent)
{
createConsumer();
createProducer();
createConnections();
QTimer::singleShot(1000, producer, SLOT(slot_publishResourceAddress()) );
}
void MainWindow::slot_log(QString str)
{
qWarning( QString("LOG> %1").arg(str).toUtf8() );
}
void MainWindow::createConnections( void )
{
connect(this, SIGNAL(signal_log(QString)), this, SLOT(slot_log(QString)));
emit signal_log(QString("Log working!"));
connect(producer, SIGNAL(signal_resourceAddress(uint_fast8_t*)), consumer, SLOT(slot_resource(uint_fast8_t*)));
}
void MainWindow::createProducer( void )
{
producer = new SingleProducer();
thread_producer = new QThread();
producer->moveToThread(thread_producer); // THIS LINE DESERVES ATTENTION
connect(producer, SIGNAL(signal_log(QString)), this, SLOT(slot_log(QString)));
}

单身制片人

#ifndef SINGLEPRODUCER_H
#define SINGLEPRODUCER_H

编辑器不让我发布更多代码...但我认为这是最相关的部分...如果没有，请告诉我。但我在 pastebin 分享了它

我的错误在哪里？
