QT 多线程事件通讯

include

static const QEvent::Type MyEventType = (QEvent::Type)QEvent::registerEventType(QEvent::User+100);

class MyClass: public QThread

{

public:

MyClass();

~MyClass();

bool event(QEvent *event);

private:

class dd: public QThread

{

public:

dd();

~dd();

void wo();

virtual void run();

MyClass *mm ;

private:

};

dd::dd()

{

mm = NULL;

}

dd::~dd()

{

}

void dd::run()

{

wo();

}

void dd::wo()

{

//可以采用外部注入

if (mm == NULL)

{

mm = new MyClass();

static QThread *ee = new QThread();

mm->moveToThread(ee);

ee->start();

}

QCoreApplication::postEvent(mm,new QEvent(MyEventType));

}

MyClass::MyClass()

{

}

MyClass::~MyClass()

{

}

bool MyClass::event(QEvent *event)

{

if (event->type() == MyEventType)

{

int fddd = 34;

}

return 0;

}

其他线程地方定义

dd *ii= new dd();

ii->wo();
