strange phenomenon when use QFile with character ~

i want to create a file in /home/username/ so i write some codes like this

    #define CONFIG_FILE_PATH "~/.config/xmlfile

    QFile file(CONFIG_FILE_PATH);
    if (!file.open(QFile:ReadOnly | QFile::Text))
    {
        if (!file.open(QFile::WriteOnly | QFile::Text))
        {
        //print error message
        }
        else
        {
        //dosomething
        file.close();
        }
    }

but when i run the program, i cannot find "xmlfile" i tried

    sudo find / -name *xmlfile*

but found nothing and the program do not show any error messages.

is there some rules with the character ~ when using QFile?

Thanks in advance.

In my experience with QFile it doesn't like any 'special' characters within the file path such as tilde, you're best off using relative or full paths. If you use QDir::homePath() it'll return a string to the current user home directory (see the documentation here: QDir special paths.
