This class doesn't know anything about units: it all depends on the different values set. A border is composed of 2 lines separated by a gap. The computed widths are the ones of each line and the gap and they can either be fix or vary. The #m_nflags member will define which widths will vary (value 0 means that all widths are fixed). The available flags are: - CHANGE_LINE1 - CHANGE_LINE2 - CHANGE_DIST For each line, the rate member is used as a multiplication factor is the width isn't fixed. Otherwise it is the width in the unit expected by the client code. */ enum class BorderWidthImplFlags { FIXED = 0, CHANGE_LINE1 = 1, CHANGE_LINE2 = 2, CHANGE_DIST = 4, }; namespace o3tl { template<> struct typed_flags<BorderWidthImplFlags> : is_typed_flags<BorderWidthImplFlags, 0x07> {}; } class SVT_DLLPUBLIC BorderWidthImpl { BorderWidthImplFlags m_nFlags; double m_nRate1; double m_nRate2; double m_nRateGap; public: BorderWidthImpl( BorderWidthImplFlags nFlags = BorderWidthImplFlags::CHANGE_LINE1, double nRate1 = 0.0, double nRate2 = 0.0, double nRateGap = 0.0 ); bool operator== ( const BorderWidthImpl& r ) const; tools::Long GetLine1 ( tools::Long nWidth ) const; tools::Long GetLine2( tools::Long nWidth ) const; tools::Long GetGap( tools::Long nWidth ) const; tools::Long GuessWidth( tools::Long nLine1, tools::Long nLine2, tools::Long nGap ); bool IsEmpty( ) const { return (0 == m_nRate1) && (0 == m_nRate2); } bool IsDouble( ) const { return (0 != m_nRate1) && (0 != m_nRate2); } }; /* vim:set shiftwidth=4 softtabstop=4 expandtab: */
