To get native components on the screen, AWT utilizes a set of peer objects that bridge the gap from pure Java to the host operating system. At some level, of course, all our components have to talk to objects that contain native methods to interact with the host operating environment; the...

If the component is a child of some other container, it is removed from that container before being added to this container. The important difference between this method andjava.awt.Container.add(Component, int)is that this method doesn't callremoveNotifyon the component while removing it from ...
All Swing components descend from the AWTContainerclass, but many of them are not used as containers. So, technically speaking, any Swing component can firecontainer events, which notify listeners that a component has been added to or removed from the container. Realistically speaking, however, on...
