示例1: isMarginSelected
bool Row::isMarginSelected(bool left_margin, DocIterator const & beg,
DocIterator const & end) const
{
pos_type const sel_pos = left_margin ? sel_beg : sel_end;
pos_type const margin_pos = left_margin ? pos_ : end_;
// Is the chosen margin selected ?
if (sel_pos == margin_pos) {
if (beg.pos() == end.pos())
// This is a special case in which the space between after
// pos i-1 and before pos i is selected, i.e. the margins
// (see DocIterator::boundary_).
return beg.boundary() && !end.boundary();
else if (end.pos() == margin_pos)
// If the selection ends around the margin, it is only
// drawn if the cursor is after the margin.
return !end.boundary();
else if (beg.pos() == margin_pos)
// If the selection begins around the margin, it is
// only drawn if the cursor is before the margin.
