    Action<CollectionFactory<DiagramCustomCommandBuilder>> configurator
)

Returns

Type	Description
DiagramViewToolbarBuilder	A reference to this instance after the method is called.

Remarks

To configure a command collection, use a multiline lambda expression. In this case, a lambda parameter performs the role of a collection factory, and its Add() method adds a new item to the collection. The Add() method returns DiagramCustomCommandBuilder whose methods you can use to configure an item.

            commands.Add(); // call methods to configure a command
            commands.Add();
        })
    )
