Member Function Documentation

void GRE_SCRIPTCONTEXT_DRAW::AttachContext (  SMLCONTEXT *&  context  )

Attach SML context. After attachment the SCRIPTCONTEXT_DRAW 'owns' the context and will destroy it when necessary. The context pointer is passed by reference and set to NULL on return to prevent external use of the context. Parameters: context  Context to attach, will set to NULL on return

ERRVALUE GRE_SCRIPTCONTEXT_DRAW::CreateContext (  RVC::GEOMETRIC &  GeoObj  )

Create SML context using RVC::GEOMETRIC object. Parameters: GeoObj  Geometric object (VECTOR, TIN, CAD, etc)

virtual void GRE_SCRIPTCONTEXT_DRAW::CreateSymbols (   )  [protected, virtual]

Reimplemented in GRE_SCRIPTCONTEXT_STYLE, and GRE_SCRIPTCONTEXT_LABEL.

void GRE_SCRIPTCONTEXT_DRAW::DestroyContext (   )  [inline]

Destroy attached SML context if any. Definition at line 68 of file scriptcontext.h.

SMLCONTEXT* GRE_SCRIPTCONTEXT_DRAW::GetContext (   )  const [inline]

Get attached SMLCONTEXT pointer. Do not free or Destroy() the returned pointer. Definition at line 73 of file scriptcontext.h.

bool GRE_SCRIPTCONTEXT_DRAW::HasContext (   )  const [inline]

Determine if have SMLCONTEXT attached. Definition at line 77 of file scriptcontext.h.

ERRVALUE GRE_SCRIPTCONTEXT_DRAW::InitDraw (  GRE_LAYERDC &  layerdc  )

Initialize using layer drawing context.

ERRVALUE GRE_SCRIPTCONTEXT_DRAW::InitDraw (  GRE_LAYER *  layer, MGD::CONTEXT *  gc, const TRANS2D_MAPGEN &  trans, bool  Is3D = false )

Initialize context variables for drawing. Parameters: layer  Layer gc  Drawing device context Is3D  3D setting for CartoScript
