/*! \defgroup graphicsGroup Graphics: Access to Graphical Resources.

|
|
* \section secGraphicsStructure General Structure of the Graphics Object
|
|
*
|
|
* First, the Graphics object is a singleton that has to be
|
|
* accessed through the static getGraphics methods.
|
|
*
|
|
* The Graphics object contains a set of DisplayStyles of which
|
|
* one is active at a time and so used to do all drawings.
|
|
* Each DisplayStyle is identified though a name and can be
|
|
* selected with the setStyle() method.
|
|
*
|
|
* The DisplayStyle itself is a set of DrawingStyle.
|
|
* Each DrawingStyle is named and provides a QColor, a QPen
|
|
* and a QBrush. QColor, QPen & QBrush are build from the
|
|
* \c (red,green,blue) , \c BorderWidth and \c pattern .
|
|
*
|
|
* Direct access to the DrawingStyle: once a DisplayStyle has
|
|
* been selected, the Graphics accessors getColor(), getPen()
|
|
* or getBrush() gives you access to the DrawingStyles.
|
|
*
|
|
* Minimal DisplayStyle: any DisplayStyle contains at least
|
|
* the following DrawingStyles :
|
|
* <ul>
|
|
* <li>\b Fallback : the default DrawingStyle.
|
|
* <li>\b Background
|
|
* <li>\b Foreground
|
|
* <li>\b Rubber
|
|
* <li>\b Phantom
|
|
* <li>\b Boundaries
|
|
* <li>\b Marker
|
|
* <li>\b SelectionDraw
|
|
* <li>\b SelectionFill
|
|
* <li>\b Grid
|
|
* <li>\b Spot
|
|
* <li>\b Ghost
|
|
* <li>\b Text
|
|
* <li>\b Undef
|
|
* </ul>
|
|
*
|
|
* Configuration parsers should create a DrawingStyle for each
|
|
* BasicLayer, with the name of the BasicLayer as the key. So the
|
|
* following code should be valid :
|
|
\code
|
|
QBrush layerBrush = Graphics::getBrush ( layer->getName() );
|
|
\endcode
|
|
* If no DrawingStyle of that name is defined, the \b Fallback
|
|
* will be used.
