TGCustomGraph.EndUpdateNodes Method

Scroll Prev Top Next More

Enables the graph to track when its nodes are changing.

Call    BeginUpdateNodes before directly modifying nodes, and    EndUpdateNodes after. The BeginUpdateNodes method calls every node's BeginUpdate method. Any new nodes created inside a BeginUpdateNodes/EndUpdateNodes block will also have its BeginUpdate methods called.

The BeginUpdateNodes method may be nested inside other BeginUpdateNodes method calls. The graph will not fire an    OnNodeChange event until an equal number of EndUpdateNodes method calls are made. Therefore, always ensure you protect the calling of the EndUpdateNodes method call in a try-finally block.
