  344. <p>This function is used to decide whether a click hits a layerable object or not.</p>
  345. <p><em>pos</em> is a point in pixel coordinates on the <a class="el" href="class_q_custom_plot.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>
  346. <p>If the item is represented not by single lines but by an area like <a class="el" href="class_q_c_p_item_rect.html" title="A rectangle. ">QCPItemRect</a> or <a class="el" href="class_q_c_p_item_text.html" title="A text label. ">QCPItemText</a>, a click inside the area returns a constant value greater zero (typically the selectionTolerance of the parent <a class="el" href="class_q_custom_plot.html" title="The central class of the library. This is the QWidget which displays the plot and interacts with the ...">QCustomPlot</a> multiplied by 0.99). If the click lies outside the area, this function returns -1.0.</p>
  347. <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>
  348. <p>The actual setting of the selection state is not done by this function. This is handled by the parent <a class="el" href="class_q_custom_plot.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>
  349. <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 selectEvent when the parent <a class="el" href="class_q_custom_plot.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 selectEvent will carry the <em>details</em>. This is useful for multi-part objects (like <a class="el" href="class_q_c_p_axis.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="class_q_c_p_layerable.html#a4001c4d0dfec55598efa4d531f2179a9">selectTest</a>. The result (i.e. the actually clicked part) can then be placed in <em>details</em>. So in the subsequent selectEvent, the decision which part was selected doesn't have to be done a second time for a single selection operation.</p>
  350. <p>You may pass 0 as <em>details</em> to indicate that you are not interested in those selection details.</p>
