Validating filename including predefined tags using QRegExp
In my application I have line edit where user can enter a file name which will be used as the file name to save image while archiving with FTP.
I have a combo box from which user can also select some predefined tags for the file name which is enclosed in . Eg:
<TIME> <DATE> <HOUR> <YEAR> <COUNTER> <XXCOUNTER> -> This tag user can edit to replace XX with 00..09
I want to allow user to manually enter these tags also. When user starts entering name the validation should be done and if found invalid then I will display the name in red color else in green color.
Also I will not allow user to enter special characters which cannot be used in file name like |, /, ?, , ", :, *
Example: Image_<COUNTER> - Valid Image_<COUNTER>< - Invalid Name<12COUNTER> - Invalid
How I can achieve validating the name which including the tags[<>] by using RegExpression[QRegExp]?
