SwPageFrm::GetCrsrOfst() tries to compare the distance to the closest
text vs. fly but does not do it right because GetCharRect()
returns just a line of width 1 on the left edge of the character;
try to figure out the entire area covered by the character via 2 calls
to GetCrsrOfst(), which gives much better clickability.

/**
|
|
* SwSpecialPos. This structure is used to pass some additional information
|
|
* during the call of SwTxtFrm::GetCharRect(). An SwSpecialPos defines a position
|
|
* inside a portion which does not have a representation in the core string or
|
|
* which is only represented by one position, e.g., field portions,
|
|
* number portions, ergo sum and quo vadis portions.
|
|
*
|
|
* nCharOfst - The offset inside the special portion. Fields and its
|
|
* follow fields are treated as one long special portion.
|
|
* nLineOfst - The number of lines between the beginning of the special
|
|
* portion and nCharOfst. A line offset required to be
|
|
* nCharOfst relative to the beginning of the line.
|
|
* nExtendRange - Setting this identifies portions which are in front or
|
|
* behind the core string (number portion, quo vadis)
|
|
*
|
|
* Examples 1)
|
|
*
|
|
* Get the position of the second character inside a number portion:
|
|
* nCharOfst = 2; nLineOfst = 0; nExtendRange = SP_EXTEND_RANGE_BEFORE;
|
|
* Call SwTxtFrm:::GetCharRect with core string position 0.
|
|
*
|
|
* Example 2)
|
|
*
|
|
* Field A - Length = 5
|
|
* Follow field B - Length = 9
|
|
* Get the position of the third character in follow field B, core position
|
|
* of field A is 33.
|
|
* nCharOfst = 7; nLineOfst = 0; nExtendRange = SP_EXTEND_RANGE_NONE;
|
|
* Call SwTxtFrm:::GetCharRect with core string position 33.
