    I need a custom mask, for example "0000 : 000 /234 1230 - 1234" to take different characters (numbers as characters too) and store all in a unique string.

    Greetings

      Hi you must define your input using the below symbols.
      "9999:9999/999 999 - 9999" for "0000 : 000 /234 1230 - 1234"
      But might need to use N also etc.
      So first you should think about what your format really is. the rules
      of it.

      Character	Meaning
      A	ASCII alphabetic character required. A-Z, a-z.
      a	ASCII alphabetic character permitted but not required.
      N	ASCII alphanumeric character required. A-Z, a-z, 0-9.
      n	ASCII alphanumeric character permitted but not required.
      X	Any character required.
      x	Any character permitted but not required.
      9	ASCII digit required. 0-9.
      0	ASCII digit permitted but not required.
      D	ASCII digit required. 1-9.
      d	ASCII digit permitted but not required (1-9).
      #	ASCII digit or plus/minus sign permitted but not required.
      H	Hexadecimal character required. A-F, a-f, 0-9.
      h	Hexadecimal character permitted but not required.
      B	Binary character required. 0-1.
      b	Binary character permitted but not required.
      >	All following alphabetic characters are uppercased.
      <	All following alphabetic characters are lowercased.
      !	Switch off case conversion.
      \	Use \ to escape the special characters listed above to use them as separators.

        you can use a QRegularExpressionValidator

        ui->lineEdit->setValidator(
        new QRegularExpressionValidator(
        QRegularExpression(
        // put here the regular expression that matches the valid input
        )
        ,ui->lineEdit
        )
        );

          ... numbers and characters:

          ui->lineEdit->setInputMask("NNNN : NNNN /NNN NNN - NNNN");

            ...or as suggested by @VRonin :

            const QString a4 = "[0-9A-Za-Z]{4}";
            const QString a3 = "[0-9A-Za-Z]{3}";
            const QString expression = QString("%1\\s\\:\\s%1\\s\\/%2\\s%2\\s\\-\\s%1").arg(a4).arg(a3); 
            QRegExp rx(expression);
            QValidator *validator = new QRegExpValidator(rx, this);
            ui->lineEdit->setValidator(validator);

              Wow, that was great, thank you very much for your help. Have you not thought about doing a book with small examples of c ++ with qt and sell it on amazon.

              Thank you very much

                @Wieland QRegExp should be banished from new code. The only place I still use it over QRegularExpression is QSortFilterProxyModel::filterRegExp just because I don't have a choice. see http://doc.qt.io/qt-5/qregularexpression.html#notes-for-qregexp-users

                @yczo you might be interested in: http://www.bogotobogo.com/cplusplus/files/c-gui-programming-with-qt-4-2ndedition.pdf

                    hello un thank you, A question more...

                    But with this code some fails. I can only the first validator a4 write, a3 don't work. The expresion dont work, only a4. Why might it be?

                    /    const QString a4 = "[0-9A-Za-Z]{4}";
                        const QString a3 = "[0-9A-Za-Z]{3}";
                        const QString expression = QString("%1\\s\\:\\s%1\\s\\/%2\\s%2\\s\\-\\s%1").arg(a4).arg(a3);
                        QRegExp rx(expression);
                        QValidator *validator = new QRegExpValidator(rx, this);
                        ui->lineEdit->setValidator(validator);
                    /your code here
                    

                    Thanks in advance

                      @yczo You also need to enter the spaces, the colon, the slash and the dash.

                        Upssss....thank you very much, as could not see the extra characters, like in ui->lineEdit->setInputMask("NNN:NNNN /NNN NNN - NNNN;X");

                        is there a way to merge both? Because

                            ui->setupUi(this);
                           // ui->lineEdit->inputMask ;

                        ui->lineEdit->setInputMask("NNN:NNN/NNN;X");
                        const QString a0 = "[0-9A-Za-Z]{3}";
                        const QString a1 = "[0-9A-Za-Z]{3}";
                        const QString a2 = "[0-9A-Za-Z]{3}";
                        const QString expression = QString("%1\\:\\%2\\/\\%3").arg(a0).arg(a1).arg(a2);
                        //ui->lineEdit->setCursorPosition(0);

                            ui->lineEdit->setCursorPosition(0);
                        

                        don't works.

                          Yes, just make the parts of the input optional, like this:

                              ui->setupUi(this);
                              ui->lineEdit->setInputMask("NNN : NNN");
                          
                              const QString a0 = "[ 0-9A-Za-z]{3}"; // space before 0
                              const QString space = "\\s";
                              const QString colon = "\\:";
                              const QString expression = QString("%1%2%3%2%1").arg(a0).arg(space).arg(colon);
                              QRegExp rx(expression);
                              QValidator *validator = new QRegExpValidator(rx, this);
                              ui->lineEdit->setValidator(validator);

                              The last question, ist posible set a max int value in the string (after other characters)?

                              for example A37 (37 is the max),We could write from A00, A01.., to A37

                                The last question, ist posible set a max int value in the string (after other characters)?

                                for example A37 (37 is the max),We could write from A00, A01.., to A37

                                Greetings

                                @yczo Yes, you can do this by adjusting the regular expression.

                                  Please, can you show me how to make it? Because I tried several options but, I have not luck.

                                  That is my idea

                                      ui->leStr->setInputMask("A99");
                                  
                                                                          //el conjunto para tanto espacios
                                      const QString id ="[ (A,M,O)]{1}";  //espacio delante para poder editar
                                      const QString cm ="[ 0-9]{2}";
                                  
                                      //const QString sl ="[0-50]{2}";
                                      const QString expr = QString("%1%2").arg(id).arg(cm);
                                      QRegExp cmp(expr);
                                      QValidator *vld = new QRegExpValidator(cmp,this);
                                      ui->leStr->setValidator(vld);
                                      ui->leStr->setCursorPosition(0);

                                    That is another idea, but don't work too

                                    ui->le1->setInputMask("99");
                                    ui->le1->setValidator(new QDoubleValidator(01,10,1,this));
                                    ui->le1->setCursorPosition(0);
                                    

                                    or

                                    ui->le1->setInputMask("99");
                                    ui->le1->setValidator(new QIntValidator(1,10,this));
                                    ui->le1->setCursorPosition(0);
                                    

                                    i don't understand what I make wrong,

                                    Greetings

                                    Edit---
                                    ok i discovered that,

                                    ui->le1->setValidator(new QIntValidator(1,10,this));

                                    work good for integers, but, only in a separate field. how to make all together, that is another story und not idea XDD

                                      For your example (max A37) it should be like this:

                                      A[0-3][0-7]
