    Hola! How I can import words from file called test.txt? For example I want import words "a dog", " a cat", "a car" and "a boy". Words are separated from other files with %% or with anything sign, because I want they individually. @a dog %% a cat %% a car %% a boy@
    Do you understand? If you don't, I can explain.
    Thank you!

      You can use QTextStream, QTextStrem::readLine() and QString::split().

        Could you write example how to use those. I'm beginner, so I don't understand yet everything in the docs.

          May be you should try reading the doc again. Example is already given "there":http://doc.qt.nokia.com/latest/qstring.html#split

          bq. QString str = "a,,b,c";
          QStringList list1 = str.split(",");
          // list1: [ "a", "", "b", "c" ]

            Ok. Now I can split them, but still, how I can use them alone?

              What do you mean by use them alone?
              QStringList is a list with strings. You can access each item seperatly.

                you may use "at()":http://doc.qt.nokia.com/stable/qlist.html#, first(), last()... etc

                  I mean that I want add each of them one at time to listWidget when I click pushButton.
                  @char* word1 = first // first should be" a dog"
                  char* word2 = second // second should be "a cat"
                  static int Time = 1;
                  if (Time == 1)
                  {
                  ui->listWidget->addItem(word1)
                  }
                  if (Time == 2)
                  {
                  ui->listWidget->addItem(word2)
                  }
                  Time == Time + 1;@
                  Do you understand now?

                    @QString str = " a dog %% a cat %% a car %% a boy";
                    QStringList list1 = str.split("%%");

                    for (int i = 0; i < list1.size(); ++i)
                    ui->listWidget->addItem(list1.at(i));@

                    Note : just wrote roughly here, not tested. :)

                    OR if you want to add one item per click,

                    in the slot for button,
                    @static int i = 0;
                    if(i < list1.size())
                    ui->listWidget->addItem(list1.at(i));
                    i++;@

                      Thanks! I was just stupid and I didn't understand how I must use "list1.at(i)" command. Now I can make my application! THANK YOU!
