示例1: paintMisspelledMark
void RowPainter::paintMisspelledMark(Row::Element const & e) const
{
if (e.font.fontInfo().nospellcheck() == FONT_ON)
return;
// if changed the misspelled marker gets placed slightly lower than normal
// to avoid drawing at the same vertical offset
FontMetrics const & fm = theFontMetrics(e.font);
int const thickness = max(fm.lineWidth(), 2);
int const y = yo_ + pi_.base.solidLineOffset() + pi_.base.solidLineThickness()
+ (e.change.changed() ? pi_.base.solidLineThickness() + 1 : 0)
+ 1 + thickness / 2;
//FIXME: this could be computed only once, it is probably not costly.
// check for cursor position
// don't draw misspelled marker for words at cursor position
// we don't want to disturb the process of text editing
DocIterator const nw = pi_.base.bv->cursor().newWord();
pos_type cpos = -1;
if (!nw.empty() && par_.id() == nw.paragraph().id()) {
cpos = nw.pos();
if (cpos > 0 && cpos == par_.size() && !par_.isWordSeparator(cpos-1))
--cpos;
else if (cpos > 0 && par_.isWordSeparator(cpos))

}
pos_type pos = e.pos;

continue;
}
FontSpan const & range = par_.getSpellRange(pos);
// Skip element which are being edited
if (range.contains(cpos)) {
// the range includes the last element
