QIntValidator not Working as Im expecting

QIntValidator not Working as Im expecting
Im set the validation on LineFdit like this

intValidator = new QIntValidator(1,999, this);
intValidator->setTop(999);
intValidator->setBottom(1);
uiPoMo->lineEdit_stId1->setValidator(intValidator);

but still LineEdit field accepting '0' and '+' ..?

I want to accept only 1 to 999 integer value.

Thanks in Advance.

@Pranit-Patil
set an Input mask as well, something like:

...
uiPoMo->lineEdit_stId1->setInputMask("00D");
uiPoMo->lineEdit_stId1->setValidator(intValidator);

You might want to take a look at this:

https://www.ics.com/blog/qt-support-input-masks-and-validators

The article is QML based, but the principles are the same and its a pretty good explanation.

Or just use uiPoMo->lineEdit_stId1->setValidator(new QRegularExpressionValidator(QRegularExpression("\\d{1,3}"),this));

@VRonin But your validator would still allow 0 to be inserted, right?

[VRonin]

uiPoMo->lineEdit_stId1->setValidator(new QRegularExpressionValidator(QRegularExpression("[1-9]\\d{0,2}"),this));

@VRonin said in QIntValidator not Working as Im expecting:

uiPoMo->lineEdit_stId1->setValidator(new QRegularExpressionValidator(QRegularExpression("[1-9]\d{0,2}"),this));

Its works for me

Thank you so much to all.
