Prepare the snap manager for the actual snapping, which includes building a list of snap targets to ignore and toggling the snap indicator.
There are two overloaded setup() methods, of which this one only allows for a single item to be ignored whereas the other one will take a list of items to ignore
|desktop ||Reference to the desktop to which this snap manager is attached |
|snapindicator ||If true then a snap indicator will be displayed automatically (when enabled in the preferences) |
|item_to_ignore ||This item will not be snapped to, e.g. the item that is currently being dragged. This avoids "self-snapping" |
|unselected_nodes ||Stationary nodes of the path that is currently being edited in the node tool and that can be snapped too. Nodes not in this list will not be snapped to, to avoid "self-snapping". Of each unselected node both the position (Geom::Point) and the type (Inkscape::SnapTargetType) will be stored |
|guide_to_ignore ||Guide that is currently being dragged and should not be snapped to |
