Searching and deleting strings



  • Hello, I've recently joined this group and used Qt for 3 months.
    I have been coding an address book. I store data in a file and use QTreeview to display them.
    My current problem is how to search a string in a file, find it and then delete it.
    Please I need help.
    Sorry for mistake!!! English is not my mother tongue.
    Have a nice day.



  • hi!
    you might be looking for this:

    @QByteArray textData;
    QFile file(myFile);
    file.open(QFile::ReadWrite|QFile::Text);
    textData= myFile.readAll();
    QString strText(textData);

    @

    and then use a :
    QString & QString::remove(const QString & str, Qt::CaseSensitivity cs = Qt::CaseSensitive)

    //check out QString docs



  • Thank you a lot, I am going to try it...



  • :) sure
