<hr><a name="_details"></a><h2>Detailed Description</h2>
The Counter Widget.
<p>
A Counter consists of a label displaying a number and one ore more (up to three) push buttons on each side of the label which can be used to increment or decrement the counter's value.<p>
A Counter has a range from a minimum value to a maximum value and a step size. The range can be specified using QwtDblRange::setRange(). The counter's value is an integer multiple of the step size. The number of steps by which a button increments or decrements the value can be specified using <a class="el" href="class_qwt_counter.html#6aa68e7fc717fb0e2e48a978301c96eb">QwtCounter::setIncSteps()</a>. The number of buttons can be changed with <a class="el" href="class_qwt_counter.html#e9241fda2e375becdb484cc2cf7752f4" title="Specify the number of buttons on each side of the label.">QwtCounter::setNumButtons()</a>.<p>
Holding the space bar down with focus on a button is the fastest method to step through the counter values. When the counter underflows/overflows, the focus is set to the smallest up/down button and counting is disabled. Counting is re-enabled on a button release event (mouse or space bar).<p>
