<p>This function is used to decide whether a click hits a layerable object or not.</p>
<p><em>pos</em> is a point in pixel coordinates on the <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> surface. This function returns the shortest pixel distance of this point to the object. If the object is either invisible or the distance couldn't be determined, -1.0 is returned. Further, if <em>onlySelectable</em> is true and the object is not selectable, -1.0 is returned, too.</p>
<p>If the object is represented not by single lines but by an area like a <a class="el" href="classQCPItemText.html">QCPItemText</a> or the bars of a <a class="el" href="classQCPBars.html">QCPBars</a> plottable, a click inside the area should also be considered a hit. In these cases this function thus returns a constant value greater zero but still below the parent plot's selection tolerance. (typically the selectionTolerance multiplied by 0.99).</p>
<p>Providing a constant value for area objects allows selecting line objects even when they are obscured by such area objects, by clicking close to the lines (i.e. closer than 0.99*selectionTolerance).</p>
<p>The actual setting of the selection state is not done by this function. This is handled by 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> when the mouseReleaseEvent occurs, and the finally selected object is notified via the selectEvent/deselectEvent methods.</p>
<p><em>details</em> is an optional output parameter. Every layerable subclass may place any information in <em>details</em>. This information will be passed to <a class="el" href="classQCPAbstractItem.html#aaf92af7b9893712959a6c073d334d88d">selectEvent</a> when 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> decides on the basis of this selectTest call, that the object was successfully selected. The subsequent call to <a class="el" href="classQCPAbstractItem.html#aaf92af7b9893712959a6c073d334d88d">selectEvent</a> will carry the <em>details</em>. This is useful for multi-part objects (like <a class="el" href="classQCPAxis.html" title="Manages a single axis inside a QCustomPlot. ">QCPAxis</a>). This way, a possibly complex calculation to decide which part was clicked is only done once in <a class="el" href="classQCPItemLine.html#a7541e5d9378ca121d07b0df3b24f7178">selectTest</a>. The result (i.e. the actually clicked part) can then be placed in <em>details</em>. So in the subsequent <a class="el" href="classQCPAbstractItem.html#aaf92af7b9893712959a6c073d334d88d">selectEvent</a>, the decision which part was selected doesn't have to be done a second time for a single selection operation.</p>
<p>You may pass 0 as <em>details</em> to indicate that you are not interested in those selection details.</p>
