<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>Controls how a plottable's data selection is drawn. </p>
<p>Each <a class="el" href="classQCPAbstractPlottable.html">QCPAbstractPlottable</a> instance has one <a class="el" href="classQCPSelectionDecorator.html">QCPSelectionDecorator</a> (accessible via <a class="el" href="classQCPAbstractPlottable.html#a7861518e47ca0c6a0c386032c2db075e">QCPAbstractPlottable::selectionDecorator</a>) and uses it when drawing selected segments of its data.</p>
<p>The selection decorator controls both pen (<a class="el" href="classQCPSelectionDecorator.html#ac2c8192e1e294aa3a4a7f32a859e3d76">setPen</a>) and brush (<a class="el" href="classQCPSelectionDecorator.html#aa74b626be518ea17055f918d423c8c2d">setBrush</a>), as well as the scatter style (<a class="el" href="classQCPSelectionDecorator.html#ab403a613289714ff4fd4a0c0371ab116">setScatterStyle</a>) if the plottable draws scatters. Since a <a class="el" href="classQCPScatterStyle.html">QCPScatterStyle</a> is itself composed of different properties such as color shape and size, the decorator allows specifying exactly which of those properties shall be used for the selected data point, via <a class="el" href="classQCPSelectionDecorator.html#a808c1607cd4e83869c04986e332455c0">setUsedScatterProperties</a>.</p>
<p>A <a class="el" href="classQCPSelectionDecorator.html">QCPSelectionDecorator</a> subclass instance can be passed to a plottable via <a class="el" href="classQCPAbstractPlottable.html#a20e266ad646f8c4a7e4631040510e5d9">QCPAbstractPlottable::setSelectionDecorator</a>, allowing greater customizability of the appearance of selected segments.</p>
<p>Use <a class="el" href="classQCPSelectionDecorator.html#a467a8d5cfcab27e862a17c797ac27b8a">copyFrom</a> to easily transfer the settings of one decorator to another one. This is especially useful since plottables take ownership of the passed selection decorator, and thus the same decorator instance can not be passed to multiple plottables.</p>
<p>Selection decorators can also themselves perform drawing operations by reimplementing <a class="el" href="classQCPSelectionDecorator.html#a4f8eb49e277063845391e803ae23054a">drawDecoration</a>, which is called by the plottable's draw method. The base class <a class="el" href="classQCPSelectionDecorator.html">QCPSelectionDecorator</a> does not make use of this however. For example, <a class="el" href="classQCPSelectionDecoratorBracket.html">QCPSelectionDecoratorBracket</a> draws brackets around selected data segments. </p>

<p>This method is called as soon as a selection decorator is associated with a plottable, by a call to <a class="el" href="classQCPAbstractPlottable.html#a20e266ad646f8c4a7e4631040510e5d9">QCPAbstractPlottable::setSelectionDecorator</a>. This way the selection decorator can obtain a pointer to the plottable that uses it (e.g. to access data points via the <a class="el" href="classQCPAbstractPlottable.html#a81fd9fd5c4f429c074785e2eb238a8e7">QCPAbstractPlottable::interface1D</a> interface).</p>
<p>If the selection decorator was already added to a different plottable before, this method aborts the registration and returns false. </p>
