Component Factory
Every FlexGantt Gantt chart is a container, which contains several other components (tree table, timeline, layer container, ...). The Gantt chart uses a factory for creating these components. This design allows an application developer to replace the default component factory with a custom one, which then can create custom components. A custom component factory needs to be passed to the constructor of a Gantt chart as it is needed early on when the chart gets created.
Example
The following code shows a custom component factory, which returns a custom layer container. This layer container is custom because it uses its own layer factory.
