[Re-ReOpened) Easy input mask

[A Former User]

@VRonin Oh yes, right. Old habits die hard :-)

[yczo]

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->getLine->setMaxLength(sizeMSG);
  //  ui->lineEdit->setInputMask("nnn;A");
   // ui->lineEdit->setInputMask("nnn;");
  //  ui->lineEdit->adjustSize();

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);
 //   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);

    ui->lineEdit->setFixedWidth(600);
    ui->lineEdit->setCursorPosition(0);

don't works.

@yczo said:

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);

[yczo]

thank you that was great.

[yczo]

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

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

[yczo]

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);

[yczo]

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

[jsulm]

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

A[0-3][0-7]
