QListWidget accessing item info (listWidget->setItemWidget)

[Archa4]

I want to get information from the item in the QListWidget. The item is set using setItemWidget.
I got an answer, that i should use cast on widget and get info that way.
I have no idea what did that mean, but i tried some things - nothing worked.
My list item contains few labels with text and some pictures. I need to get the text that is in the labels.
My last thought was:

QWidget *widget = qobject_cast<QWidget *>(Custom_Widget);

QWidget *widget = qobject_cast<QWidget *>(Custom_Widget);

To copy to clipboard, switch view to plain text mode 

But i think that is completely wrong...
Also i tried

QWidget *widget = static_cast<QListWidgetItem *>(listWidget->item(0));

QWidget *widget = static_cast<QListWidgetItem *>(listWidget->item(0));

To copy to clipboard, switch view to plain text mode 

But this is still wrong... Can someone help?
