QLineEdit with inputmask 9999;0
I am currently looking into a QLineEdit behaviour if I have a input maks set to a lineEdit file which shall be used for a PIN entry.
The problem is if the user only changes 2 digits out of the 4 the lineEdit->text() only returns the changed values and not the full string.
How can I achieve it that i get the full string back also if nothing changed?
So default value is 0000 but if I do a linEdit->text() it just returns a empty string.
Am I missing something?
Yes, you missed a key point from the doc:
The blank characters are always removed from the text after editing.
You should add a validator to enforce the number of character entered before going further.
Thank you SGaist, poining to it ;)
You're welcome !
I'd also recommend using _ as placeholder char rather than 0, otherwise people will think there's a default PIN or maybe no protection at all.
