Simple QObject::connect question

[Bryku]

Hi. I'm new to QT and I have a good-programming-style-type problem. I want to connect 2 objects. Until now , i wrote some simple applications , and connected objects that one contains another. For example:

class c : public QWidget
{
private:
	QPushButton *button;
public:
	c() 
	{
		...
		connect(button,SIGNAL(signal()),this,SLOT(slot()));
		...
	}
};

class c : public QWidget
{
private:
	QPushButton *button;
public:
	c() 
	{
		...
		connect(button,SIGNAL(signal()),this,SLOT(slot()));
		...
	}
};

To copy to clipboard, switch view to plain text mode 

And it was simple and easy.

But what if i want to connect to objects that none of them is containing another ? In "connect" i have to pass pointers to sender and reciever. Should I pass the pointer to another object in a constructor ? For example:

class ObjectA : public QWidget
{
	...
public slots:
	void slot();
	...
};
 
class ObjectB : public QWidget
{
	...
signals:
	void signal();
public:
	ObjectB(ObjectA *p)
	{
		...
		connect(this,SIGNAL(signal()),p,SLOT(slot()));
		...
	}
};

class ObjectA : public QWidget
{
	...
public slots:
	void slot();
	...
};

class ObjectB : public QWidget
{
	...
signals:
	void signal();
public:
	ObjectB(ObjectA *p)
	{
		...
		connect(this,SIGNAL(signal()),p,SLOT(slot()));
		...
	}
};

To copy to clipboard, switch view to plain text mode 

Is that a good way to do that ? It works, but I believe something is wrong with that. What if i want to connect one object with twenty anothers , so i neet do pass 20 pointers in a constructor ?
