Class Description

Function Set for Sets of Objects.

MFnSet is the function set that is used for manipulating sets of objects. Sets in Maya are dependency nodes, so it is possible for one set to contain others.

A set is a list of dependency nodes and dag nodes. Sets are useful for keeping track of lists of objects for many purposes such as selection or applying common rendering parameters. Sets in Maya are also dependency nodes, so it is possible for one set to contain others.

MStatus getMembers ( MSelectionList members,
bool  flatten 
) const

Get the members of this set as a selection list.

This information is provided as a selection list so that all of the path information is retained for DAG nodes.

It is possible to ask for the returned list to be flattened. This means that all sets that exist inside this set will be expanded into a list of their contents.

Typically set members are updated using callbacks. When members are added/removed, the set members ar marked as dirty. The set members are only updated on request such as invoking getMembers(). This method can be useful in scenarios where callbacks are temporarily suspended (eg. during file IO operations).

Parameters
[out]membersstorage for the returned list of members
[in]flattenwhether to flatten the returned list.
