\subsection{Detailed Description}
The abstract base class for all entries in a \hyperlink{class_q_c_p_legend}{Q\+C\+P\+Legend}. 

It defines a very basic interface for entries in a \hyperlink{class_q_c_p_legend}{Q\+C\+P\+Legend}. For representing plottables in the legend, the subclass \hyperlink{class_q_c_p_plottable_legend_item}{Q\+C\+P\+Plottable\+Legend\+Item} is more suitable.

Only derive directly from this class when you need absolute freedom (e.\+g. a custom legend entry that\textquotesingle{}s not even associated with a plottable).

You must implement the following pure virtual functions\+: \begin{DoxyItemize}
\item draw (from \hyperlink{class_q_c_p_layerable}{Q\+C\+P\+Layerable})\end{DoxyItemize}
You inherit the following members you may use\+: \begin{TabularC}{2}
\hline
\hyperlink{class_q_c_p_legend}{Q\+C\+P\+Legend} $\ast${\bfseries m\+Parent\+Legend}  &A pointer to the parent \hyperlink{class_q_c_p_legend}{Q\+C\+P\+Legend}. \\\cline{1-2}
Q\+Font {\bfseries m\+Font}  &The generic font of the item. You should use this font for all or at least the most prominent text of the item.  \\\cline{1-2}
\end{TabularC}

This does not cause the item to be added to {\itshape parent}, so \hyperlink{class_q_c_p_legend_a3ab274de52d2951faea45a6d975e6b3f}{Q\+C\+P\+Legend\+::add\+Item} must be called separately.

Layout elements are sensitive to events inside their outer rect. If {\itshape pos} is within the outer rect, this method returns a value corresponding to 0.\+99 times the parent plot\textquotesingle{}s selection tolerance. However, layout elements are not selectable by default. So if {\itshape only\+Selectable} is true, -\/1.\+0 is returned.

See \hyperlink{class_q_c_p_layerable_a4001c4d0dfec55598efa4d531f2179a9}{Q\+C\+P\+Layerable\+::select\+Test} for a general explanation of this virtual method.

\hyperlink{class_q_c_p_layout_element}{Q\+C\+P\+Layout\+Element} subclasses may reimplement this method to provide more specific selection test behaviour.
