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 <a class="el" href="class_qwt_dbl_range.html#a2">QwtDblRange::setRange()</a>. 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#a16">QwtCounter::setIncSteps()</a>. The number of buttons can be changed with <a class="el" href="class_qwt_counter.html#a14">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>
Example: <div class="fragment"><pre><span class="preprocessor">#include "../include/qwt_counter.h></span>
<a class="code" href="class_qwt_counter.html">QwtCounter</a> *cnt;
cnt = <span class="keyword">new</span> <a class="code" href="class_qwt_counter.html#a0">QwtCounter</a>(parent, name);
cnt-><a class="code" href="class_qwt_dbl_range.html#a2">setRange</a>(0.0, 100.0, 1.0); <span class="comment">// From 0.0 to 100, step 1.0</span>
cnt-><a class="code" href="class_qwt_counter.html#a14">setNumButtons</a>(2); <span class="comment">// Two buttons each side</span>
cnt-><a class="code" href="class_qwt_counter.html#a16">setIncSteps</a>(QwtCounter::Button1, 1); <span class="comment">// Button 1 increments 1 step</span>
cnt-><a class="code" href="class_qwt_counter.html#a16">setIncSteps</a>(QwtCounter::Button2, 20); <span class="comment">// Button 2 increments 20 steps</span>
connect(cnt, SIGNAL(<a class="code" href="class_qwt_counter.html#l1">valueChanged</a>(<span class="keywordtype">double</span>)), my_class, SLOT(newValue(<span class="keywordtype">double</span>)));
