How does node expansion work in neo4j browser?

Question

When I expand (double-click) a node in the neo4j browser, it expands to show all its neighbors. Does it call a query to do that or is some other mechanism used? I ask because I want to replicate this behavior in a web application to render a neo4j graph.

Answer 1

The neo4j Browser does a query when you double-click on an un-"expanded" node.

The double-click event handler code is here, which eventually calls this code to make the query.
