<h1>KModifierKeyInfo Class Reference</h1>
<code>from PyKDE4.kdeui import *</code>
<p>
Inherits: <a href="http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qobject.html">QObject</a><br />
<h2>Detailed Description</h2>
<p>Get information about the state of the keyboard's modifier keys.
</p>
<p>
This class provides cross-platform information about the state of the
keyboard's modifier keys and the mouse buttons and allows to change the
state as well.
</p>
<p>
It recognizes two states a key can be in:
<ul><li><i>locked</i>: eg. caps-locked (aka toggled)</li>
<li><i>latched</i>: the key is temporarily locked but will be unlocked upon
the next keypress.</li></ul>
</p>
<p>
An application can either query the states synchronously (@see isKeyLatched,
<dl class="see" compact><dt><b>See also:</b></dt><dd> isKeyLocked) or connect to KModifierKeyInfo's signals to be notified about
changes (@see keyLatched, <dl class="see" compact><dt><b>See also:</b></dt><dd> keyLocked).
</dd></dl>
