Create a connection for the parent class

[maratk1n]

Hi all!
I have a class for the main window, class A and class B, which inherits from class A:

MainWindow::MainWindow(){
	...
	A a;
	connect(&a, SIGNAL(remoteSignal(bool)), this, SLOT(updateStates(bool)));
	a.start();
	B b;
	connect(&b, SIGNAL(remoteSignal(bool)), this, SLOT(updateStates(bool)));
}
 
A::A()
{
 
}
void A::start(){
	emit remoteSignal(true)
}
 
B::B()
{
	A::start();
}

MainWindow::MainWindow(){
	...
	A a;
	connect(&a, SIGNAL(remoteSignal(bool)), this, SLOT(updateStates(bool)));
	a.start();
	B b;
	connect(&b, SIGNAL(remoteSignal(bool)), this, SLOT(updateStates(bool)));
}

A::A()
{
	
}
void A::start(){
	emit remoteSignal(true)
}

B::B()
{
	A::start();
}

To copy to clipboard, switch view to plain text mode 

If I call the start method from object b for the parent class, there will not be any connections configured. How can I customize them?
Thanks!
