    Default Retrieve userData of a comboBox item

    The manual says:

    Qt Code:
    1. void QComboBox::addItem ( const QString & text, const QVariant & userData = QVariant() )
    2. //Adds an item to the combobox with the given text, and containing the specified userData. The item is appended to the list of existing items.
    To copy to clipboard, switch view to plain text mode 

    but how can i get the userData of a given item?

    And what/how did you add as user data? May we see the addItem() statement?

    sample code:

    Qt Code:
    1. QString bookTitle = "Beginning Joomla!";
    2. QString isbn13String = "978-1590598481";
    3. titleComboBox->addItem(bookTitle, isbn13String);
    To copy to clipboard, switch view to plain text mode 

    Thanks

    In this case use :
    Qt Code:
    1. QString data = titleComboBox->itemData(0).toString();
    To copy to clipboard, switch view to plain text mode
