Hey guys , I've been searching for a solution:
it works " this is an example " but I still can insert values greater than 100!!
I searched and found this won't limit the line edit ,because the user can still enter a " . " to set the value , so what can I do to change this the user can only insert values between 0.0 to 100.0 ?
VALID_DOUBLE = new QDoubleValidator;
it doesn't really lets the max limit 100 or under but still better since you can't really go above 999 which is nice
