UiPanel

lumin.ui. UiPanel

UiPanel - Represents an area to group elements and to confine cursor
interactions within a shaped boundary.

The boundary shape is a rounded rectangular area, from sharp corner to circular,
where the cursor can be restricted within or provide means to move between
different UiPanel areas.

Constructor

Inherited From:

Adds a child to the current Node, removing it from its current parent.

A child can only have a single Parent

Parameters:

The Node to add as a child to this Node.

Returns:

true if successful, false if failed

Type
boolean

addExternalGravityWell(uiNode)

Use the external gravity well list to add specific UiNode gravity wells
for consideration with this Panel when those nodes are not normally descendants.
This is only intended for relatively small lists of nodes and may not be
performant if very large lists of external nodes are used.

with an event TransformAnimationEventData.

Parameters:
