Detailed Description

Access to Graphical Resources.

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 (red,green,blue) , BorderWidth and 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 :

• Fallback : the default DrawingStyle.
• Background
• Foreground
• Rubber
• Phantom
• Boundaries
• Marker
• SelectionDraw
• SelectionFill
• Grid
• Spot
• Ghost
• Text
• Undef

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 :

QBrush layerBrush = Graphics::getBrush ( layer->getName() );

If no DrawingStyle of that name is defined, the Fallback will be used.
