Attribute change callback.

This method is called whenever one of a node's attributes is changed.

Parameters

node	The changed XML node
name	GQuark corresponding to the attribute's name
old_value	Old value of the modified attribute. Is a nullptr when the attribute is added.
new_value	New value of the modified attribute. Is a nullptr when the attribute is removed.

Reimplemented from Inkscape::XML::NodeObserver.

◆ reset_item()

void Inkscape::UI::ShapeEditor::reset_item ( )

private

FIXME: This thing is only called when the item needs to be updated in response to repr change.

Why not make a reload function in KnotHolder?

note that it is not certain that this is an SPItem; it could be a LivePathEffectObject.
