<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>
172
<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>
175
<a class="el" href="class_qwt_picker_tracker_machine.html" title="A state machine for indicating mouse movements.">QwtPickerTrackerMachine</a></li>
176
<li>Single points<br/>

181
<a class="el" href="class_qwt_picker_polygon_machine.html" title="A state machine for polygon selections.">QwtPickerPolygonMachine</a></li>
183
<p>While these state machines cover the most common ways to collect points it is also possible to implement individual machines as well.</p>
184
<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>
185
<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>

<p>The reason, why a <a class="el" href="class_qwt_picker.html#ac5bc0a5f7054c407195ce9ee1d0cf394">selection()</a> differs from the picked points depends on the application requirements. F.e. :</p>
469
<li>A rectangular selection might need to have a specific aspect ratio only.<br/>
471
<li>A selection could accept non intersecting polygons only.<br/>
476
<p>The example below is for a rectangular selection, where the first point is the center of the selected rectangle. </p>
