<h1>KRestrictedLine Class Reference</h1>
<code>from PyKDE4.kdeui import *</code>
<p>
Inherits: <a href="../kdeui/KLineEdit.html">KLineEdit</a> → QLineEdit → QWidget → QObject<br />
<h2>Detailed Description</h2>
<p>A line editor for restricted character sets.
</p>
<p>
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.
</p>
<p>
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.
</p>
<p>
This is almost like setting a QRegExpValidator on a KLineEdit;
the difference is that with KRestrictedLine it can all be done in Qt designer.
