Member Function Documentation

void RS_Preview::addMeasuringLabel (  const RS_String &  label, const RS_Vector &  position, double  direction, RS_GraphicView &  graphicView )

Adds a label typically used to display a measuring result. Parameters: label  The string to display. position  Position of the label. direction  The direction of the element that would be in the way of the label. E.g. direction PI/4 means that the label will be left-bottom aligned so it does not intersect with a line that points in direction PI/4.

void RS_Preview::addPreviewEntity (  RS_Entity *  entity, RS_EntityContainer *  subContainer = NULL )

Adds an entity to this preview and removes any attributes / layer connectsions before that. This function ensures that the preview will not get too big and might actually drop or simplify entities.

void RS_Preview::addRectangle (  const RS_Vector &  v1, const RS_Vector &  v2, RS_EntityContainer *  subContainer = NULL )

Adds an entity to this preview. The entity is always added. This can be used for crucial preview entities such as a label of a measuring tool.

void RS_Preview::addSelectionFrom (  RS_EntityContainer &  srcContainer, RS_EntityContainer *  subContainer = NULL )

Adds all selected entities from 'container' to the preview (unselected). Parameters: subContainer  Add the selection to this sub container of the preview. Can be NULL for direct adding to the preview.

void RS_Preview::addStretchablesFrom (  RS_EntityContainer &  container, const RS_Vector &  v1, const RS_Vector &  v2, RS_EntityContainer *  subContainer = NULL )

Adds all entities in the given range and those which have endpoints in the given range to the preview. Invisible and locked entities are not added.
