示例1: caretPos
void RenderInline::caretPos(int offset, int flags, int &_x, int &_y, int &width, int &height)
{
_x = -1;
RenderBlock *cb = containingBlock();
bool rtl = cb->style()->direction() == RTL;
bool outsideEnd = flags & CFOutsideEnd;
// I need to explain that: outsideEnd contains a meaningful value if
// and only if flags & CFOutside is set. If it is not, then randomly
// either the first or the last line box is returned.
// This doesn't matter because the only case this can happen is on an
// empty inline element, whose first and last line boxes are actually
// the same.
InlineFlowBox *line = !outsideEnd ^ rtl ? firstLineBox() : lastLineBox();
if(!line)
{ // umpf, handle "gracefully"
RenderFlow::caretPos(offset, flags, _x, _y, width, height);
return;
}
_x = line->xPos();
width = 1; // ### regard CFOverride
// Place caret outside the border
if(flags & CFOutside)
{
RenderStyle *s = element() && element()->parent() && element()->parent()->renderer() ? element()->parent()->renderer()->style() : style();
const QFontMetrics &fm = s->fontMetrics();
_y = line->yPos() + line->baseline() - fm.ascent();
height = fm.height();
if(!outsideEnd ^ rtl)
{
_x -= line->marginBorderPaddingLeft();
}
else
{
_x += line->width() + line->marginBorderPaddingRight();
}
}
else
{
const QFontMetrics &fm = style()->fontMetrics();
_y = line->yPos() + line->baseline() - fm.ascent();

}
int absx, absy;
if(cb && cb->absolutePosition(absx, absy))
{
// kdDebug(6040) << "absx=" << absx << " absy=" << absy << endl;
_x += absx;
_y += absy;
}
else
{
// we don't know our absolute position, and there is no point returning
// just a relative one
_x = _y = -1;
}
