Defined in MContingentLineBreakerL:

• IsLegalBreakAfterL(TInt,TInt,TBool)Determines if a break is legal after the picture at aTextPosition.
• IsLegalBreakBeforeL(TInt,TInt,TBool)Determines if a break is legal before the picture at aTextPosition.

virtual TBool IsLegalBreakBeforeL(TInt aTextPosition, TInt aPrecedingClass, TBool aHasSpaces)=0;

Description

Determines if a break is legal before the picture at aTextPosition.

Parameters

TInt aTextPosition The position of a character of line breaking class ECbLineBreakClass in the text as supplied to MLineBreaker::GetLineBreak(const TDesC16 &,TInt,TInt,TBool,MContingentLineBreaker *,TInt &,TInt &)const, which may refer to a picture. TInt aPrecedingClass The class of the character preceding aTextPosition. TBool aHasSpaces ETrue if spaces separate the preceding class from this.

Return value

TBool ETrue if a line break is legal here.

virtual TBool IsLegalBreakAfterL(TInt aTextPosition, TInt aFollowingClass, TBool aHasSpaces)=0;

Description

Determines if a break is legal after the picture at aTextPosition.

Parameters

TInt aTextPosition The position of a character of line breaking class ECbLineBreakClass in the text as supplied to MLineBreaker::GetLineBreak(const TDesC16 &,TInt,TInt,TBool,MContingentLineBreaker *,TInt &,TInt &)const, which may refer to a picture. TInt aFollowingClass The class of the character immediately following aTextPosition. TBool aHasSpaces ETrue if spaces separate the preceding class from this.

Return value
