The arrow keys can beused to move from section to section within the QTimeEdit box. Theuser can automatically be moved to the next section once they completea section using <a href="#setAutoAdvance">setAutoAdvance</a>(). Times appear in hour, minute, secondorder. It is recommended that the QTimeEdit be initialised with atime, e.g.<p> <pre> <a href="qtime.html">QTime</a> timeNow = QTime::<a href="qtime.html#currentTime">currentTime</a>(); QTimeEdit *timeEdit = new QTimeEdit( timeNow, this ); timeEdit-><a href="#setRange">setRange</a>( timeNow, timeNow.<a href="qtime.html#addSecs">addSecs</a>( 60 * 60 ) ); </pre> Here we've created a QTimeEdit widget set to the current time. We'vealso set the minimum value to the current time and the maximum timeto one hour from now.<p> The maximum and minimum values for a time value in the time editordefault to the maximum and minimum values for a <a href="qtime.html">QTime</a>. You canchange this by calling <a href="#setMinValue">setMinValue</a>(), <a href="#setMaxValue">setMaxValue</a>() or <a href="#setRange">setRange</a>().<p> Terminology: A QTimeWidget consists of three sections, one each for thehour, minute and second. You can change the separator character using<a href="#setSeparator">setSeparator</a>(), by default the separator is read from the system's settings.<p> <center><img src="datetimewidgets.png" alt="Date Time Widgets"></center> <p> <p>See also <a href="qtime.html">QTime</a>, <a href="qdateedit.html">QDateEdit</a>, <a href="qdatetimeedit.html">QDateTimeEdit</a>, <a href="advanced.html">Advanced Widgets</a> and <a href="time.html">Time and Date</a>.<p> <hr><h2>Member Function Documentation</h2><h3 class=fn><a name="QTimeEdit"></a>QTimeEdit::QTimeEdit ( <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 )</h3> Constructs an empty time edit with parent <em>parent</em> and name <em>name</em>.<p> <h3 class=fn><a name="QTimeEdit-2"></a>QTimeEdit::QTimeEdit ( const <a href="qtime.html">QTime</a> & time, <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 )</h3>This is an overloaded member function, provided for convenience.
