Detailed Description

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. The only remarkable point is that the HAS_CONTENT flag is cleared.

Member Function Documentation

void dw::Ruler::draw	(	core::View *	view,
		core::Rectangle *	area
	)			[protected, virtual]

Area is given in widget coordinates.

Implements dw::core::Widget.

References dw::core::Widget::drawWidgetBox().

core::Iterator * dw::Ruler::iterator	(	core::Content::Type	mask,
		bool	atEnd
	)			[virtual]

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.

Todo:

TextIterator?
