Detailed Description

An container is a component to organize widgets. You need to inherit this class and implement some necessary methods to customize your own container components.
The features that distinguish from widgets are following:

  1. Widget cannot have children
  2. If disable or enable method of container component is called, the all children of that will be disabled or enabled. You can customize this behavior by overriding doDisable and doEnable methods together.
  3. Widget must inherit from Component but container component must inherit from ContainerComponent
