<p>This function applies the default antialiasing setting to the specified <em>painter</em>, using the function <a class="el" href="classQCPLayerable.html#acb663e375d2d36dc5c55021ee5a2119b">applyAntialiasingHint</a>. It is the antialiasing state the painter is put in, when <a class="el" href="classQCPAbstractLegendItem.html#a97dedc084c672359710f16b31d046d1d">draw</a> is called on the layerable. If the layerable has multiple entities whose antialiasing setting may be specified individually, this function should set the antialiasing state of the most prominent entity. In this case however, the <a class="el" href="classQCPAbstractLegendItem.html#a97dedc084c672359710f16b31d046d1d">draw</a> function usually calls the specialized versions of this function before drawing each entity, effectively overriding the setting of the default antialiasing hint.</p>
<p><b>First example:</b> <a class="el" href="classQCPGraph.html" title="A plottable representing a graph in a plot. ">QCPGraph</a> has multiple entities that have an antialiasing setting: The graph line, fills and scatters. Those can be configured via <a class="el" href="classQCPLayerable.html#a4fd43e89be4a553ead41652565ff0581">QCPGraph::setAntialiased</a>, <a class="el" href="classQCPAbstractPlottable.html#a089d6b5577120239b55c39ed27c39536">QCPGraph::setAntialiasedFill</a> and <a class="el" href="classQCPAbstractPlottable.html#a2f03f067ede2ed4da6f7d0e4777a3f02">QCPGraph::setAntialiasedScatters</a>. Consequently, there isn't only the <a class="el" href="classQCPAbstractPlottable.html#a59a80773c5cefc05a0646ac8e1149ed5">QCPGraph::applyDefaultAntialiasingHint</a> function (which corresponds to the graph line's antialiasing), but specialized ones like <a class="el" href="classQCPAbstractPlottable.html#a8d06a59ea23324cce6330ebf2262c0ed">QCPGraph::applyFillAntialiasingHint</a> and <a class="el" href="classQCPAbstractPlottable.html#ac95f26b15a1e5d9c7bd2c0a46d760fc9">QCPGraph::applyScattersAntialiasingHint</a>. So before drawing one of those entities, <a class="el" href="classQCPGraph.html#a659218cc62c2a7786213d9dd429c1c8d">QCPGraph::draw</a> calls the respective specialized applyAntialiasingHint function.</p>
<p><b>Second example:</b> <a class="el" href="classQCPItemLine.html" title="A line from one point to another. ">QCPItemLine</a> consists only of a line so there is only one antialiasing setting which can be controlled with <a class="el" href="classQCPLayerable.html#a4fd43e89be4a553ead41652565ff0581">QCPItemLine::setAntialiased</a>. (This function is inherited by all layerables. The specialized functions, as seen on <a class="el" href="classQCPGraph.html" title="A plottable representing a graph in a plot. ">QCPGraph</a>, must be added explicitly to the respective layerable subclass.) Consequently it only has the normal <a class="el" href="classQCPAbstractItem.html#a82a408b38a93be750b934fe847a018cb">QCPItemLine::applyDefaultAntialiasingHint</a>. The <a class="el" href="classQCPItemLine.html#a1fc045dd33919f8006df0692aeb0e84a">QCPItemLine::draw</a> function doesn't need to care about setting any antialiasing states, because the default antialiasing hint is already set on the painter when the <a class="el" href="classQCPAbstractLegendItem.html#a97dedc084c672359710f16b31d046d1d">draw</a> function is called, and that's the state it wants to draw the line with. </p>

<p>This event is called when the layerable shall be selected, as a consequence of a click by the user. Subclasses should react to it by setting their selection state appropriately. The default implementation does nothing.</p>
<p><em>event</em> is the mouse event that caused the selection. <em>additive</em> indicates, whether the user was holding the multi-select-modifier while performing the selection (see <a class="el" href="classQCustomPlot.html#a8fc96e3b5138a06759a2a90c166df516">QCustomPlot::setMultiSelectModifier</a>). if <em>additive</em> is true, the selection state must be toggled (i.e. become selected when unselected and unselected when selected).</p>
<p>Every selectEvent is preceded by a call to <a class="el" href="classQCPAbstractLegendItem.html#ac834bf9003c491e5064a31e2a7de418d">selectTest</a>, which has returned positively (i.e. returned a value greater than 0 and less than the selection tolerance of the parent <a class="el" href="classQCustomPlot.html" title="The central class of the library. This is the QWidget which displays the plot and interacts with the ...">QCustomPlot</a>). The <em>details</em> data you output from <a class="el" href="classQCPAbstractLegendItem.html#ac834bf9003c491e5064a31e2a7de418d">selectTest</a> is fed back via <em>details</em> here. You may use it to transport any kind of information from the selectTest to the possibly subsequent selectEvent. Usually <em>details</em> is used to transfer which part was clicked, if it is a layerable that has multiple individually selectable parts (like <a class="el" href="classQCPAxis.html" title="Manages a single axis inside a QCustomPlot. ">QCPAxis</a>). This way selectEvent doesn't need to do the calculation again to find out which part was actually clicked.</p>
<p><em>selectionStateChanged</em> is an output parameter. If the pointer is non-null, this function must set the value either to true or false, depending on whether the selection state of this layerable was actually changed. For layerables that only are selectable as a whole and not in parts, this is simple: if <em>additive</em> is true, <em>selectionStateChanged</em> must also be set to true, because the selection toggles. If <em>additive</em> is false, <em>selectionStateChanged</em> is only set to true, if the layerable was previously unselected and now is switched to the selected state.</p>
