QTableWidget and DoubleClicked(QtableWidgetItem *) problem

[skrzypu]

Hi,

When I doubleclick in item of QTableWidget it connect with given slot.
This slot for end of it functionality send signal, there is nothing after this signal.
Siganal run method which delete current class in center of MainWidget and show another.
But my program don't show this another, program close.

When I use button to emit these same signal everythink is ok.

Everything is in deleted widget.

Anybody knows why is that??

Seeing some code would indeed help in understanding the problem. Sounds like QObject::deleteLater() might be required.

Important code:

class1 
{
   class1
  {
     ...
     connect(this->ui.List,SIGNAL(itemDoubleClicked(QTableWidgetItem *)),this,SLOT(slot1(QTableWidgetItem *)));
     ...less important things
  }
 
  ...
   slot1
   {
       emit this->anotherView();
   }
}

class1 
{
   class1
  {
     ...
     connect(this->ui.List,SIGNAL(itemDoubleClicked(QTableWidgetItem *)),this,SLOT(slot1(QTableWidgetItem *)));
     ...less important things
  }
  
  ...
   slot1
   {
       emit this->anotherView();
   }
}

To copy to clipboard, switch view to plain text mode 

and in main class:

MainClass
{
   ...
   //anotherView run this method:
   void changeanotherWidget(){
	QWidget *buffor;
	buffor = this->centralWidget();
	if(buffor)
		delete buffor;
 
	this->anotherWidget= new AnotherWidget();
	this->setCentralWidget(viewPatient);
 
	...
        //some connections
        ...
     }
}

MainClass
{
   ...
   //anotherView run this method:
   void changeanotherWidget(){
	QWidget *buffor;
	buffor = this->centralWidget();
	if(buffor)
		delete buffor;
	
	this->anotherWidget= new AnotherWidget();
	this->setCentralWidget(viewPatient);
	
	...
        //some connections
        ...
     }
}

To copy to clipboard, switch view to plain text mode 

there is no more, i connect to signal anotherView only this slot

QObject::deleteLater -- don't help
