Question

I have a code someone wrote and there

 this->llBankCode = new widgetLineEditWithLabel(tr("Bankleitzahl"), "", Qt::AlignTop, this);
 QRegExpValidator *validatorBLZ = new QRegExpValidator(this);
 validatorBLZ->setRegExp(QRegExp( "[0-9]*", Qt::CaseSensitive));
 this->llBankCode->lineEdit->setValidator(validatorBLZ);

as it can be seen from this code, is that validatorBLZ can accept only numbers between 0 and 9. I would like to change it, that validatorBLZ would be able to get as an input whitespace as well (but not to start with a whitespace), but it wont be shown.

Example:
if i try to copy & paste a string of the format ’22 34 44′, the result would be an empty field. What i would like to happen is that the string ’22 34 44′ will be shown in the field as ‘223444’.

How could i do it?

Answer 1

You could try using:

QString string = "22 34 44";
string.replace(QString(" "), QString(""));

That will replace any spaces with a non-space.
