ObjectArray

Description

The ObjectArray object provides a container to group Object instances. This can be useful e.g. when Gather is used to merge multiple lists or object hierarchies.

› Inherits:: Object
› Inherited by:: Application

Properties

Methods

Signals

Properties

objects

This property holds a list of Object instances.

› Type:: List<Object>
› Signal:: objectsChanged()
› Attributes:: Readonly

Signals

objectsDataChanged(SignedInteger index)

This signal is emitted whenever the List.dataChanged() signal is emitted, i.e. the item at index in the objects list itself emitted the dataChanged() signal.

Example
