For example, <tt>CTRL + Key_P</tt> might be a sequenceused as a shortcut for printing a document. The key codes arelisted in <a href="qnamespace-h.html">qnamespace.h</a>. As an alternative, use <a href="qt.html#Modifier-enum">UNICODE_ACCEL</a> with the unicode code point of the character. Forexample, <tt>UNICODE_ACCEL + 'A'</tt> gives the same key sequence as <a href="qt.html#Key-enum">Key_A</a>.<p> Key sequences can be constructed either from an integer key code,or from a human readable translatable string. A key sequence canbe cast to a <a href="qstring.html">QString</a> to obtain a human readable translated versionof the sequence. Translations are done in the "QAccel" context.<p> <p>See also <a href="qaccel.html">QAccel</a> and <a href="misc.html">Miscellaneous Classes</a>.<hr><h2>Member Function Documentation</h2><h3 class=fn><a name="QKeySequence"></a>QKeySequence::QKeySequence ()</h3>Constructs an empty key sequence.<h3 class=fn><a name="QKeySequence-2"></a>QKeySequence::QKeySequence ( const <a href="qstring.html">QString</a> & key )</h3>Creates a key sequence from the string <em>key</em>.

The strings "Ctrl", "Shift"and "Alt" are recognized, as well as their translated equivalentsin the "QAccel" context (using <a href="qobject.html#tr">QObject::tr</a>()).<p> This contructor is typically used with <a href="qobject.html#tr">tr</a>(), so that accelerator keys can be replaced intranslations:<p> <pre> <a href="qpopupmenu.html">QPopupMenu</a> *file = new <a href="qpopupmenu.html">QPopupMenu</a>( this ); file-><a href="qmenudata.html#insertItem">insertItem</a>( tr("&Open..."), this, SLOT(open()), <a href="#QKeySequence">QKeySequence</a>( tr("Ctrl+O", "File|Open") ) ); </pre> <p> Note the <tt>"File|Open"</tt> translator comment.
