Property Value

Type Description

A nullable integer value specifying the order index by which nodes are arranged.


When modifying this property value via the Model Editor, note the specific meaning if the Index is zero. Initially, the Index is zero, and it means that the property value has not been changed, the node order is not customized, and nodes are arranged by default. However, if you set Index, for example, to “1”, then subsequently set it to “0”, then it will be recognized as a user difference (saved in the XAFML file), and will actually influence the node order.


You can rearrange the child nodes of a particular node via the ALT+UP ARROW and ALT+DOWN ARROW shortcuts in the Model Editor. Their indexes will be updated automatically to correspond the rearrangements
