Detailed Description

A line editor for restricted character sets.

The KRestrictedLine widget is a variant of QLineEdit which accepts only a restricted set of characters as input. All other characters will be discarded and the signal invalidChar() will be emitted for each of them.

Valid characters can be passed as a QString to the constructor or set afterwards via setValidChars(). The default key bindings of QLineEdit are still in effect.

This is almost like setting a QRegExpValidator on a KLineEdit; the difference is that with KRestrictedLine it can all be done in Qt designer.

KDE Restricted Line Edit allowing all characters but 'o'
