changeListener
Runs onChange on the change event of a component that fires one - the widgets changeListener lists.
onChange is read when the event fires, so writing a fresh lambda on every recomposition registers nothing again.
Return
this chain with the change callback declared on it.
Parameters
receives the event, which carries nothing but its source: read the new state off the component itself.

Runs onChange on the change event of a component of type T that fires one, with that component as this.
Return
this chain with the change callback declared on it.
Parameters
read when the event fires. A parameter of the enclosing composable shadows the receiver, so reach it through this. Read the component's state through the receiver; writing a property the composition declares through it makes the second manager listener describes.

Runs onChange on the change event of a component of type targetType that fires one, with that component as this. An event sourced anywhere else is refused; see listener.
A JColorChooser publishes through its selection model, so its change events name that model rather than the chooser and are not ones this overload can scope.
Return
this chain with the change callback declared on it.
Parameters
the component type the node and every event's source are both checked against.
read when the event fires.

Attaches a ChangeListener (addChangeListener/removeChangeListener) to a component that fires change events (JSlider, JSpinner, JTabbedPane, JProgressBar, AbstractButton, JViewport, JColorChooser). A color chooser publishes its change events through its selectionModel, and the registration follows that model when the chooser is given another one.
Return
this chain with the change listener declared on it.
Parameters
attached by identity, so a remembered instance stays put while a fresh one on every pass is detached and re-added.
