*** *** gtkwidgexts::GtkxEntryMask GtkxEntryMask is a widget based upon the GtkEntry widget, which extends adding a type to the text. Once the type is set, the widget only allows valid characters to be typed. These are the main features: - The supported types are: - STRING - NUMBER - CURRENCY - DATE - TIME - DATETIME - The mask property states which characters are valid. For example: type=STRING, mask="AA-99"
Your mask seems to be quite limited, I'd suggest to use regular expressions here. You never know what restrictions we in our sheer madness^W^Winfinite wisdom want to impose on our users.
The first two characters MUST be alphanumeric, the third character MUST be a hyphen and the last two charactres MUST be numbers. The maximun length of the string is 5.
Hmm, what if the string needs to be exactly 5 characters long? My best
idea is to have a set of allowed characters which can be typed in
('[A-Za-z0-9]' or somesuch) and a regular expression on which the string
will be tested afterwards ('^[A-Za-z0-9]{2}-[A-Za-z0-9]{2}$'). Yes,
regular expressions are hard to write and even harder to read, but they
are most flexible, which is a big bonus in my eyes.

Ever noticed that common sense isn't really all that common?
