std::cout displaying a hex value instead of a string.

[johnny_sparx]

I wanted to dump some QStrings to the console. I am using the following code:

std::cout<<"#"<<Item_Parent->child(i)->data(DB_SERIES__PATH,Qt::DisplayRole).toString().constData()<<"\n";

std::cout<<"#"<<Item_Parent->child(i)->data(DB_SERIES__PATH,Qt::DisplayRole).toString().constData()<<"\n";

To copy to clipboard, switch view to plain text mode 

It seems fine but I get the following at the console:

#0x815b8aa
#0x816ee42
#0x8175eb2

#0x815b8aa
#0x816ee42
#0x8175eb2

To copy to clipboard, switch view to plain text mode 

I want to see the string. I thought constData() would work, but it seems like cout is not processing it right. Suggestions?

try toStdString()

Try this:

#include <QString>
#include <iostream>
int main() {
    const QString s("test 1234567890");
    std::cout << s.constData() << std::endl; // returns QChar *
    std::cout << s.toAscii().constData() << std::endl; // returns char *
}

#include <QString>
#include <iostream>
int main() {
    const QString s("test 1234567890");
    std::cout << s.constData() << std::endl; // returns QChar *
    std::cout << s.toAscii().constData() << std::endl; // returns char *
}

To copy to clipboard, switch view to plain text mode 

and have a look at QString::constData() vs. QByteArray::constData().
