/**

* @short 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.
