Hello everyone, I tryed to make a input mask kind "02-03-21". I searched on internet, but all examples are dificult for the first step. That is my idea, but don't works ui->lineEdit->setInputMask("nnn;"); ui->lineEdit->setCursorPosition(0); I would appreciate some help. Greetings

@ yczo said: is there a way to merge both? 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);

For your example (max A37) it should be like this:
```
A[0-3][0-7]
```
