Properties

ROOT_TYPE

Object

Constructor reference used to determine the root of a Widget-based object tree.

Currently used to control the behavior of the root attribute so that recursing up the object heirarchy can be constrained to a specific type of Widget. Widget authors should set this property to the constructor function for a given Widget implementation.

Attributes

depth

Number readonly

Number representing the depth of this Widget relative to the root Widget in the object heirarchy.

Default: -1

Fires event depthChange

Fires when the value for the configuration attribute depth is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

    • prevVal Any
      The value of the attribute, prior to it being set.
    • newVal Any
      The value the attribute is to be set to.
    • attrName String
      The name of the attribute being set.
    • subAttrName String
      If setting a property within the attribute's value, the name of the sub-attribute property being set.

index

Number readonly

Number representing the Widget's ordinal position in its parent Widget.

Fires event indexChange
