static const char * | OOFM_NAME [NUM_OOFM] |
Widget for drawing (horizontal) rules.
This is really an empty widget, the HTML parser puts a border around it, and drawing is done in dw::core::Widget::drawWidgetBox.
Ruler implements RegardingBorder; this way, it is simpler to fit the ruler exactly within the space between floats. Currently, the drawn area of the ruler is too large (but most of the superfluous part is hidden by the floats); this problem will soon solved here in the "dillo_grows" repository.

Return an iterator for this widget.
mask can narrow the types returned by the iterator, this can enhance performance quite much, e.g. when only searching for child widgets.
With atEnd == false, the iterator starts before the beginning, i.e. the first call of dw::core::Iterator::next will let the iterator point on the first piece of contents. Likewise, With atEnd == true, the iterator starts after the last piece of contents, call dw::core::Iterator::prev in this case.
