QDataWidgetMapper and QLineEdit with validator

[jarda]

Hello all,

I have form with several QLineEdit widgets managed by QDataWidgetMapper.
QLineEdit has assigned QRegExpValidator with pattern "[A-Z]{4}" - (four characters must be filled).
QDataWidgetMapper is set to manual submit policy.
But if I enter only two characters and call submit() on QDataWidgetMapper, it still save data into the model.

Do I do something wrong way or how to ensure valid input?
Thanks in advance,
Jaroslav

Hi Jaroslav

1. I assume from your post that you want to actually match ANY four characters. If this is correct, then your expression should be "[A-Z | a-z]{4}" or else you'll only match CAPITALS.
2. To solve your problem regarding the validation, you should implement something along the lines of:
   @myLineEdit->setValidator(validator)

if(myLineEdit->hasAcceptableInput()) {
//capture data
}@

Hope that helps!
