C++ (Cpp) EdgeElement::dst Examples

Example #1

File: arrangeLinksCommand.cpp Project: Jurabek/qreal

void ArrangeLinksCommand::arrange()
{
	NodeElement *node = dynamic_cast<NodeElement *>(mElement);
	EdgeElement *edge = dynamic_cast<EdgeElement *>(mElement);
	if (node) {
		arrange(node);
	}
	if (edge) {
		NodeElement *src = edge->src();
		NodeElement *dst = edge->dst();
		if (src) {
			arrange(src);
		}
		if (dst) {
			arrange(dst);
		}
	}
}
