|
|
First, the \mbox{\hyperlink{classHurricane_1_1Graphics}{Graphics}} object is a singleton that has to be accessed through the static get\+Graphics methods.
|
|
|
|
The \mbox{\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 \mbox{\hyperlink{classHurricane_1_1DisplayStyle}{Display\+Style}} is identified though a name and can be selected with the set\+Style() method.
|
|
|
|
The \mbox{\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 \mbox{\hyperlink{classHurricane_1_1DisplayStyle}{Display\+Style}} has been selected, the \mbox{\hyperlink{classHurricane_1_1Graphics}{Graphics}} accessors get\+Color(), get\+Pen() or get\+Brush() gives you access to the Drawing\+Styles.
|
|
|
|
Minimal \mbox{\hyperlink{classHurricane_1_1DisplayStyle}{Display\+Style}}\+: any \mbox{\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 \textbf{ 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 \textbf{ Basic\+Layer}, with the name of the \textbf{ Basic\+Layer} as the key. So the following code should be valid \+:
|
|
\begin{DoxyCode}
|
|
QBrush layerBrush = \mbox{\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. |
