<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>
<ul>
<li>Nothing<br/>
<a class="el" href="class_qwt_picker_tracker_machine.html" title="A state machine for indicating mouse movements.">QwtPickerTrackerMachine</a></li>
<li>Single points<br/>
<a class="el" href="class_qwt_picker_click_point_machine.html" title="A state machine for point selections.">QwtPickerClickPointMachine</a>, <a class="el" href="class_qwt_picker_drag_point_machine.html" title="A state machine for point selections.">QwtPickerDragPointMachine</a></li>
<li>Rectangles<br/>
<a class="el" href="class_qwt_picker_click_rect_machine.html" title="A state machine for rectangle selections.">QwtPickerClickRectMachine</a>, <a class="el" href="class_qwt_picker_drag_rect_machine.html" title="A state machine for rectangle selections.">QwtPickerDragRectMachine</a></li>
<li>Polygons<br/>
<a class="el" href="class_qwt_picker_polygon_machine.html" title="A state machine for polygon selections.">QwtPickerPolygonMachine</a></li>
</ul>
<p>While these state machines cover the most common ways to collect points it is also possible to implement individual machines as well.</p>
<p><a class="el" href="class_qwt_picker.html" title="QwtPicker provides selections on a widget.">QwtPicker</a> translates the picked points into a selection using the adjustedPoints method. adjustedPoints is intended to be reimplemented to fixup the selection according to application specific requirements. (F.e. when an application accepts rectangles of a fixed aspect ratio only.)</p>
<p>Optionally <a class="el" href="class_qwt_picker.html" title="QwtPicker provides selections on a widget.">QwtPicker</a> support the process of collecting points by a rubberband and tracker displaying a text for the current mouse position.</p>
<dl class="user"><dt><b>Example</b></dt><dd><div class="fragment"><pre class="fragment">#include <qwt_picker.h>

picker->setTrackerMode(QwtPicker::ActiveOnly);
picker->setRubberBand(QwtPicker::RectRubberBand); </pre></div><br/>
</dd></dl>
<p>The state machine triggers the following commands:</p>
<ul>
<li><a class="el" href="class_qwt_picker.html#a49cb19aea451e275c5d376235e5a1d83">begin()</a><br/>
