\subsection{Descripción detallada}
A straight line that spans infinitely in both directions. 

 It has two positions, {\itshape point1} and {\itshape point2}, which define the straight line.

This function is used to decide whether a click hits a layerable object or not.

{\itshape pos} is a point in pixel coordinates on the \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} surface. This function returns the shortest pixel distance of this point to the object. If the object is either invisible or the distance couldn\textquotesingle{}t be determined, -\/1.\+0 is returned. Further, if {\itshape only\+Selectable} is true and the object is not selectable, -\/1.\+0 is returned, too.

If the item is represented not by single lines but by an area like \hyperlink{class_q_c_p_item_rect}{Q\+C\+P\+Item\+Rect} or \hyperlink{class_q_c_p_item_text}{Q\+C\+P\+Item\+Text}, a click inside the area returns a constant value greater zero (typically the selection\+Tolerance of the parent \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} multiplied by 0.\+99). If the click lies outside the area, this function returns -\/1.\+0.

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$\ast$selection\+Tolerance).

The actual setting of the selection state is not done by this function. This is handled by the parent \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} when the mouse\+Release\+Event occurs, and the finally selected object is notified via the select\+Event/deselect\+Event methods.

{\itshape details} is an optional output parameter. Every layerable subclass may place any information in {\itshape details}. This information will be passed to select\+Event when the parent \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} decides on the basis of this select\+Test call, that the object was successfully selected. The subsequent call to select\+Event will carry the {\itshape details}. This is useful for multi-\/part objects (like \hyperlink{class_q_c_p_axis}{Q\+C\+P\+Axis}). This way, a possibly complex calculation to decide which part was clicked is only done once in \hyperlink{class_q_c_p_item_straight_line_a64cc3796f58ce856012732603edb2f1c}{select\+Test}. The result (i.\+e. the actually clicked part) can then be placed in {\itshape details}. So in the subsequent select\+Event, the decision which part was selected doesn\textquotesingle{}t have to be done a second time for a single selection operation.

You may pass 0 as {\itshape details} to indicate that you are not interested in those selection details.
