\subsection{Detailed Description}
Access to Graphical Resources. \hypertarget{group__graphicsGroup_secGraphicsStructure}{}\subsection{General Structure of the Graphics Object}\label{group__graphicsGroup_secGraphicsStructure}
First, the \hyperlink{classHurricane_1_1Graphics}{Graphics} object is a singleton that has to be accessed through the static get\-Graphics methods.

The \hyperlink{classHurricane_1_1Graphics}{Graphics} object contains a set of Display\-Styles of which one is active at a time and so used to do all drawings. Each \hyperlink{classHurricane_1_1DisplayStyle}{Display\-Style} is identified though a name and can be selected with the set\-Style() method.

The \hyperlink{classHurricane_1_1DisplayStyle}{Display\-Style} itself is a set of Drawing\-Style. Each Drawing\-Style is named and provides a Q\-Color, a Q\-Pen and a Q\-Brush. Q\-Color, Q\-Pen \& Q\-Brush are build from the {\ttfamily }(red,green,blue) , {\ttfamily Border\-Width} and {\ttfamily pattern} .

Direct access to the Drawing\-Style\-: once a \hyperlink{classHurricane_1_1DisplayStyle}{Display\-Style} has been selected, the \hyperlink{classHurricane_1_1Graphics}{Graphics} accessors get\-Color(), get\-Pen() or get\-Brush() gives you access to the Drawing\-Styles.

Minimal \hyperlink{classHurricane_1_1DisplayStyle}{Display\-Style}\-: any \hyperlink{classHurricane_1_1DisplayStyle}{Display\-Style} contains at least the following Drawing\-Styles \-: 
\begin{DoxyItemize}
\item {\bfseries Fallback} \-: the default Drawing\-Style. 
\item {\bfseries Background} 
\item {\bfseries Foreground} 
\item {\bfseries {\bf Rubber}} 
\item {\bfseries Phantom} 
\item {\bfseries Boundaries} 
\item {\bfseries Marker} 
\item {\bfseries Selection\-Draw} 
\item {\bfseries Selection\-Fill} 
\item {\bfseries Grid} 
\item {\bfseries Spot} 
\item {\bfseries Ghost} 
\item {\bfseries Text} 
\item {\bfseries Undef} 
\end{DoxyItemize}

Configuration parsers should create a Drawing\-Style for each {\bf Basic\-Layer}, with the name of the {\bf Basic\-Layer} as the key. So the following code should be valid \-: 
\begin{DoxyCode}
QBrush layerBrush = \hyperlink{classHurricane_1_1Graphics_ad67a43df460d5c5d5179a81d2a72c9a9}{Graphics::getBrush} ( layer->getName() );
\end{DoxyCode}
 If no Drawing\-Style of that name is defined, the {\bfseries Fallback} will be used.
