static

Hidden text range information - static and non-version.

@descr Determines if a given position is inside a hidden text range. The static version tries to obtain a valid SwScriptInfo object via the SwTextNode, otherwise it calculates the values from scratch. The non-static version uses the internally cached information for the calculation.

Parameters

rNode	The text node.
nPos	The given position that should be checked.
rnStartPos	Return parameter for the start position of the hidden range. COMPLETE_STRING if nPos is not inside a hidden range.
rnEndPos	Return parameter for the end position of the hidden range. 0 if nPos is not inside a hidden range.
rnEndPos	Return parameter that contains all the hidden text ranges. Optional.

Returns: returns true if there are any hidden characters in this paragraph.
