Member Function Documentation

virtual void te::layout::AbstractScene::calculateMatrixViewScene ( )

protectedpure virtual

Method that calculates the transformation matrix of the scene. This matrix will be set in each QGraphicsView class that watches this scene.

Implemented in te::layout::Scene.

virtual void te::layout::AbstractScene::calculateWindow ( double  wMM, double  hMM  )

protectedpure virtual

Method that calculates the ratio of the size of the scene with the paper size. This calculation is necessary so that the paper always is centered in the scene.

Parameters

wMM	width of physical screen in millimeters
hMM	height of physical screen in millimeters

Implemented in te::layout::Scene.

te::gm::Envelope te::layout::AbstractScene::getSceneBox ( )

virtual

Method that return the scene box.

Parameters

graphic

object

virtual void te::layout::AbstractScene::init ( double  screenWMM, double  screenHMM  )

pure virtual

Method that starts the scene and configures. Calculates the transformation matrix of the scene and calculates the ratio of the size of the scene with the paper size.

Parameters

screenWMM	width of physical screen in millimeters
screenHMM	height of physical screen in millimeters

Implemented in te::layout::Scene.

virtual void te::layout::AbstractScene::insertItem ( ItemObserver *  item )

pure virtual

Method that inserts a graphic object in the scene. Inverts the matrix of the object if necessary, ex.: TextItem.

Parameters

item	graphic object

Implemented in te::layout::Scene.
