<a class="el" href="class_qwt_picker.html">QwtPicker</a> provides selections on a widget.
35
<a class="el" href="class_qwt_picker.html">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>
36
<a class="el" href="class_qwt_picker.html">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>
37
<dl class="user" compact><dt><b>Example </b></dt><dd><div class="fragment"><pre class="fragment">#include <qwt_picker.h>
39
QwtPicker *picker = new QwtPicker(widget);
40
picker->setTrackerMode(QwtPicker::ActiveOnly);
41
connect(picker, SIGNAL(selected(const QwtPolygon &)), ...);
43
// emit the position of clicks on widget
44
picker->setSelectionFlags(QwtPicker::PointSelection | QwtPicker::ClickSelection);
48
// now select rectangles
49
picker->setSelectionFlags(QwtPicker::RectSelection | QwtPicker::DragSelection);
50
picker->setRubberBand(QwtPicker::RectRubberBand); </pre></div><br>
52
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">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>
53
The commands are initiated from a small state machine (<a class="el" href="class_qwt_picker_machine.html">QwtPickerMachine</a>) that translates mouse and key events. There are a couple of predefined state machines for point, rect and polygon selections. The <a class="el" href="class_qwt_picker.html#a42f0efb5aa8bcf4f2097a49fb96f886">selectionFlags()</a> control which one should be used. It is possible to use other machines by overloading <a class="el" href="class_qwt_picker.html#aad63b94d03f8ebb363ed51d7c2a0dd2">stateMachine()</a>.<p>
54
The picker is active (<a class="el" href="class_qwt_picker.html#9ee030f985edfa20d0f896534b9b611b">isActive()</a>), between <a class="el" href="class_qwt_picker.html#49cb19aea451e275c5d376235e5a1d83">begin()</a> and <a class="el" href="class_qwt_picker.html#d258c518257cf2f52326905a36efb0c4">end()</a>. In active state the rubberband is displayed, and the tracker is visible in case of trackerMode is ActiveOnly or AlwaysOn.<p>
55
The cursor can be moved using the arrow keys. All selections can be aborted using the abort key. (<a class="el" href="class_qwt_event_pattern.html#8fb57ceb9982d5583a1bf568e37d3007">QwtEventPattern::KeyPatternCode</a>)<p>

<dl class="warning" compact><dt><b>Warning:</b></dt><dd>In case of QWidget::NoFocus the focus policy of the observed widget is set to QWidget::WheelFocus and mouse tracking will be manipulated for ClickSelection while the picker is active, or if <a class="el" href="class_qwt_picker.html#aa6987f2fbc65e6468891c779201461b">trackerMode()</a> is AlwayOn. </dd></dl>
