How to start a function in parent with QItemDelegate

[aekilic]

Hello all

We have QItemDelegate like this.

if(index.column() == 12)
	{
        QLineEdit *editor = new QLineEdit(parent);
	connect(editor, SIGNAL(returnPressed()), parent, SLOT(x_x()));
        return editor;
	}

if(index.column() == 12)
	{
        QLineEdit *editor = new QLineEdit(parent);
	connect(editor, SIGNAL(returnPressed()), parent, SLOT(x_x()));
        return editor;
	}

To copy to clipboard, switch view to plain text mode 

I would like to start x_x function from the parent, but I was not able to do it? Do you have any idea?

pass pointer to needed object trought ctor of delegate and then use it in connect.

void MyDelegate::setCustomHandler(QWidget *handler)
{
       m_handler = handler;
}
....
if(index.column() == 12)  {
       QLineEdit *editor = new QLineEdit(parent);
       connect(editor, SIGNAL(returnPressed()), m_handler, SLOT(x_x()));
       return editor;
} 
....
MyDelegate *delegate = new MyDelegate();
delegate->setCustomHandler(this);
....

void MyDelegate::setCustomHandler(QWidget *handler)
{
       m_handler = handler;
}
....
if(index.column() == 12)  {
       QLineEdit *editor = new QLineEdit(parent);
       connect(editor, SIGNAL(returnPressed()), m_handler, SLOT(x_x()));
       return editor;
} 
....
MyDelegate *delegate = new MyDelegate();
delegate->setCustomHandler(this);

I get a error like this.

m_handler' undeclared (first use
this function)

[spirit]

you have to declare it like a class member, i.e.

class MyDeleaget: public QItemDelegate
{
.....
private:
       QWidget *m_handler;
};

class MyDeleaget: public QItemDelegate
{
.....
private:
       QWidget *m_handler;
};
