Member Function Documentation

void LineRegionsSupport::setFirstLine (  int  first  )

Sets start line position of line structures. This position tells, that first line structure refers not to first line of text, but to first parameter value.

void LineRegionsSupport::setBackground (  const RegionDefine *  back  )

Background region define, which is used to fill transparent regions. If background is null, then regions with transparent fields would leave these fields unfilled

void LineRegionsSupport::setRegionMapper (  const RegionMapper *  rds  )

Choose the source of RegionDefine definitions. This source returns information about mapping Region objects into RegionDefine objects.

LineRegion * LineRegionsSupport::getLineRegions (  int  lno  )  const

Returns LineRegion object for lno line number. This object is linked with all other stored LineRegion objects
