signals emitted but slot dont call

[danics]

Hi,
i have a object in my UI thread and i send a pointer of this object to another thread then i emit a signal of object but connected slot don't called:

class MyObject : public QObject {
  ...
  void checkMyEvents() [
      ...
     emit processfinished();
     ...  
  }
 
 void start() {
  ...
   othread->start();
  ...
 }
signals:
  void processfinished();
private:
 MyThread* otherad;
}
 
class MyThread : public QThread
{
public:
 void run() {
    ...
    obj->checkMyEvents();
    ...
 }
 
 MyObject* obj;
}
 
main() {
 ....
 MyObject obj;
 QObject::connect(&obj, SIGNAL(processfinished()), &anotherObj, SLOT(showresults());
 ....
}

class MyObject : public QObject {
  ...
  void checkMyEvents() [
      ...
     emit processfinished();
     ...  
  }

 void start() {
  ...
   othread->start();
  ...
 }
signals:
  void processfinished();
private:
 MyThread* otherad;
}

class MyThread : public QThread
{
public:
 void run() {
    ...
    obj->checkMyEvents();
    ...
 }

 MyObject* obj;
}

main() {
 ....
 MyObject obj;
 QObject::connect(&obj, SIGNAL(processfinished()), &anotherObj, SLOT(showresults());
 ....
}

in debug mode i can see signals emitted but slot don't call
whats wrong in my code?
