Masking QLineEdit to accept white space.

[savaliya_ambani]

Hi, All,

I Have problem related to QLineEdit.

I am using 2 QLineEditne is User ID and Another is User Name.
I want to allow only digits 0-9 in User Id, and a-z,A-Z,0-9,and white space in User Name.

I have masked User Id with "000000" to accept only 6 digits.And works fine.
But, how can i mask User Name to allow a-z,A-Z,0-9,and white space in User Name.

how can i do this?

I want to allow only digits 0-9

Just use a QIntValidator.

and a-z,A-Z,0-9,and white space in User Name.

Use a QRegExpValidator

Thanks For this,

But i need to check the Validation every time some thing entered into the LineEdit Box.
And see if it returns a valid OR invalid.

cant it be automatic? Like if i mask User Id with "000000", Than i didnt have to check Any thing.It will just accepts Digits 0 to 9.

And i mask user name with "nnnnnnnnnnnnn", but this is not accepting white space.What should i Do?

The validation I suggested ARE automatic, and do exactly what you want.
Read their documentation.
