pthread instead QThread

[spirit]

yes, you can't call GUI methods in another thread. use signals/slots or custom event for communication between main and worker thread.

Ok

I've implemented custom signal/slots:

#ifndef PORTA_H
#define PORTA_H
 
#include <QObject>
 
class Porta : public QObject{
 
	public:
		static const int DISCRETE=0;
		static const int BINARY=1;
 
		Porta ();
		int getValue ();
		virtual void setType (int t);
 
	protected:
		int value;
		pthread_t thread;
		int type;
 
		int createThread ();
		static void *startThread (void *obj);
		virtual void threadFunction(void)=0;
 
	signals:
		void valueChanged();
 
};
 
#endif

#ifndef PORTA_H
#define PORTA_H

#include <QObject>

class Porta : public QObject{

	public:
		static const int DISCRETE=0;
		static const int BINARY=1;

		Porta ();
		int getValue ();
		virtual void setType (int t);

	protected:
		int value;
		pthread_t thread;
		int type;

		int createThread ();
		static void *startThread (void *obj);
		virtual void threadFunction(void)=0;

	signals:
		void valueChanged();

};

#endif

How can I connect this custom signal with my custom slot??

Class Porta is missing the required Q_OBJECT macro.
