QValidator, more than one in a one QLineEdit

[mrdebug]

Hi everybody. I need to accept a string formatted like this:

E12:34,2a

where

• the first charter (E) can be E or U
• a time value (12:34)
• an alphanumeric value (2a)

Is possible or have I to split in 3 QLineEdit objects?

Hi
you might want to take a look at

My rule is
([I,O]| )([0-2]| )([0-9]| ):([0-5]| )([0-9]| )
to have for example
I08:00 or O18:30
Is there a way to have it in uppercase?
08:00 and 18:30 are times fields. Is there a way to force value from 00 to 23? Now I can write 25 for example.

Regards.

Hi,

([0-1][0-9]|2[0-3])for the 00 to 23

Another option may be subclassing validator.

Perfetc, and to have uppercase? I need only I or O and not i o.
Is there a way to have replace mode instead of insert mode in the qlineedit? I need to rewrite without select or delete.

If you are using only uppercase letters in QRegExp you should be fine. E.g. "[IO]{1,1}" shall match only an uppercase 'I' or an uppercase 'O'.
