<p><a class="el" href="class_qwt_picker.html" title="QwtPicker provides selections on a widget. ">QwtPicker</a> filters all enter, leave, mouse and keyboard events of a widget and translates them into an array of selected points.</p>
<p>The way how the points are collected depends on type of state machine that is connected to the picker. Qwt offers a couple of predefined state machines for selecting:</p>

<p>While these state machines cover the most common ways to collect points it is also possible to implement individual machines as well.</p>
