| class TTmDocPos |
A structure for holding a raw document position that can be converted to or from an x-y position and compared ordinally, which cannot be done with the more abstract TTmDocPosSpec class. Leading edges are distinguished from trailing edges so that bidirectional hit testing and cursor positioning can distinguish between 'after character N', and 'before character N + 1', which may be some distance apart if N and N + 1 are in runs of opposite directionality.

| TBool | iLeadingEdge |
| TInt | iPos |
| TTmDocPos | ( | ) | [inline] |
Constructs a TTmDocPos object, setting iPos to 0 and iLeadingEdge to false. This is the lowest legal value for a TTmDocPos object. A trailing edge comes before a leading edge because it is the trailing edge of the character before the position, while the leading edge is that of the character after the position. ('Leading' means the first to be encountered when traversing the document in logical order).
| TTmDocPos | ( | TInt | aPos, |
| TBool | aLeadingEdge | ||
| ) | [inline] | ||
Constructs a TTmDocPos object, setting iPos to aPos and iLeadingEdge to aLeadingEdge.
| TBool | operator!= | ( | const TTmDocPos & | aPos | ) | const [inline] |
The not equal operator. True if both sides have different values.
| const TTmDocPos & aPos |
| TBool | operator< | ( | const TTmDocPos & | aPos | ) | const [inline] |
Smaller than operator. True if the right side of the operator is further on in the document than the left hand side.
| const TTmDocPos & aPos |
| TBool | operator<= | ( | const TTmDocPos & | aPos | ) | const [inline] |
Smaller than or equal to operator. True if the right side of the operator is further on in the document than the left hand side or if both sides are identical.
