I am reading javadocs of an API (see attached).
One line says:
Implement this class if you are using custom Swing or AWT components, ...

What exactly is meant by "custom"?
If I have a class that extends say, JCheckbox, is that a custom component?

If I were to take a guess, I'd say that it's a custom component that was implemented with the help of swing libraries.

I could be wrong though.

My guess is that custom Swing or AWT component is the class which you wrote yourself but which extends Swing or AWT compohnent

Say you wrote

 class MyPanel extends JPanel {
..

}

so MyPanel is your custom swing coponent

From "How to Support Assistive Technologies"

http://download.oracle.com/javase/tutorial/uiswing/misc/access.html
----------------------------------------------------------------------
If you create a custom component, make sure it supports accessibility. In particular, be aware that subclasses of JComponent are not automatically accessible. Custom components that are descendants of other Swing components should override inherited accessibility information as necessary. For more information, see Concepts: How Accessibility Works and Making Custom Components Accessible.

From this we can infer the answer to your question

Q: If I have a class that extends say, JCheckbox, is that a custom component?
A: Yes
