<a class="el" href="class_qwt_picker.html" title="QwtPicker provides selections on a widget.">QwtPicker</a> provides selections on a widget.
<p>
<a class="el" href="class_qwt_picker.html" title="QwtPicker provides selections on a widget.">QwtPicker</a> filters all mouse and keyboard events of a widget and translates them into an array of selected points. Depending on the <a class="el" href="class_qwt_picker.html#446d9f87a6796d62949c62d77c51e3eb">QwtPicker::SelectionType</a> the selection might be a single point, a rectangle or a polygon. The selection process is supported by optional rubberbands (rubberband selection) and position trackers.<p>
<a class="el" href="class_qwt_picker.html" title="QwtPicker provides selections on a widget.">QwtPicker</a> is useful for widgets where the event handlers can't be overloaded, like for components of composite widgets. It offers alternative handlers for mouse and key events.<p>
<dl class="user" compact><dt><b>Example </b></dt><dd><div class="fragment"><pre class="fragment">#include <qwt_picker.h>
QwtPicker *picker = new QwtPicker(widget);
picker->setTrackerMode(QwtPicker::ActiveOnly);
connect(picker, SIGNAL(selected(const QwtPolygon &)), ...);
// emit the position of clicks on widget
picker->setSelectionFlags(QwtPicker::PointSelection | QwtPicker::ClickSelection);
...
// now select rectangles
picker->setSelectionFlags(QwtPicker::RectSelection | QwtPicker::DragSelection);
picker->setRubberBand(QwtPicker::RectRubberBand); </pre></div><br>
</dd></dl>
The selection process uses the commands <a class="el" href="class_qwt_picker.html#49cb19aea451e275c5d376235e5a1d83">begin()</a>, <a class="el" href="class_qwt_picker.html#5dd2e0ce6b2a6cc50e345ec13aef9255">append()</a>, <a class="el" href="class_qwt_picker.html#59d92670978f200edb61e429afa06542">move()</a> and <a class="el" href="class_qwt_picker.html#d258c518257cf2f52326905a36efb0c4" title="Close a selection setting the state to inactive.">end()</a>. <a class="el" href="class_qwt_picker.html#5dd2e0ce6b2a6cc50e345ec13aef9255">append()</a> adds a new point to the selection, <a class="el" href="class_qwt_picker.html#59d92670978f200edb61e429afa06542">move()</a> changes the position of the latest point.<p>
The commands are initiated from a small state machine (<a class="el" href="class_qwt_picker_machine.html" title="A state machine for QwtPicker selections.">QwtPickerMachine</a>) that translates mouse and key events. There are a couple of predefined state machines for point, rect and polygon selections.
