Is there a way to only allow certain characters to be entered into a QEntryElement? For example, say I have the following string of characters "ABCDefgh1234". Is there a way to only allow those 12 characters to be entered? Note, lowercase abcd will not be allowed and uppercase EFGH will not be allowed.
Hopefully I'm posting this in the right section.
