示例1:
static void
draw_string(void* _context, const char* string, size_t length, float deltaSpace,
float deltaNonSpace)
{
DrawingContext* context = reinterpret_cast<DrawingContext *>(_context);
// NOTE: the picture data was recorded with a "set pen location"
// command inserted before the "draw string" command, so we can
// use PenLocation()
BPoint location = context->CurrentState()->PenLocation();
escapement_delta delta = { deltaSpace, deltaNonSpace };
context->ConvertToScreenForDrawing(&location);
location = context->GetDrawingEngine()->DrawString(string, length,
location, &delta);
context->ConvertFromScreenForDrawing(&location);
context->CurrentState()->SetPenLocation(location);
// the DrawingEngine/Painter does not need to be updated, since this
// effects only the view->screen coord conversion, which is handled
// by the view only
}
