Find the node that is closest/farthest from the origin.

Parameters

origin	Point of reference
search_selected	Consider selected nodes
search_unselected	Consider unselected nodes
closest	If true, return closest node, if false, return farthest

Returns: The matching node, or an empty iterator if none found

◆ hideDragPoint()

void Inkscape::UI::PathManipulator::hideDragPoint ( )

Hide the curve drag point until the next motion event.

This should be called at the beginning of every method that can delete nodes. Otherwise the invalidated iterator in the dragpoint can cause crashes.
