GRAPH NODE WITH AUTOMATICALLY ADJUSTING INPUT PORTS

A graphical user interface system that visually represents a graph node having multiple input ports, and that automatically adjusts the number of input ports to the graph node (602) as open input ports are connected to upstream graph node(s) (601) and/or as used input ports are disconnected from upstream graph node(s). Upon detecting that a set of one or more input ports (623) has just been connected (643) to one or more upstream graph nodes, the system may automatically add one or more additional input ports (624) to the visual representation of the graph node without explicit user instruction. Upon detecting that a set of one or more of the input ports has just been disconnected from one or more upstream graph nodes, the system may automatically remove the determined one or more input ports from the visual representation of the graph node. 种图形用户界面系统，其视觉地表示具有多个输入端口的图形节点，并且在开放输入端口被连接到上游图形节点(601)时和/或在使用的输入端口从上游图形节点被断开连接时，自动地调节去往图形节点(602)的输入端口的数目。在检测到个或多个输入端口(623)的集合刚被连接(643)到个或多个上游图形节点时，系统可以自动地向图形节点的视觉表示添加个或多个
