To expand or collapse all of the item’s children
Example: Listing the mayaClock device
If you ran the mayaClockDemo MEL script, the clock name (clock) should be listed in the left column in the Device Outliner. If it is not, follow the directions in “To expand or collapse an item”.
To show all of the device’s children
The first level of children in the clock are the three axes: hours, minutes, and seconds.
For complex devices, an indented list of axes is displayed, each with its own children. Eventually a device listing ends with attribute attachments. The attachments describe how the device is connected to Maya attributes.
