http://lilisworking.wordpress.com/2009/08/26/pilot-study-of-jbutton-button/ JToggle button ” implements toggle functionality inherited by JCheckBox and JRadioButton. Can be instantiated or subclassed to create two-state buttons.” Tutorial does not have special chapter for this comprehensive button type. There’s only a link to JToggleButton Class: http://java.sun.com/javase/7/docs/api/javax/swing/JToggleButton.html.

http://lilisworking.wordpress.com/2009/12/14/basic-button-feature/ JButtons have a ‘name’ property (as well as actionCommand), which is implemented by setName(). Not taught in tutorial. Programmers have to look up in Component class. This is confusing comparing to setText(), which set text icon on JButtons. Swing tutorial says “As the ButtonDemo example shows, a Swing button can display both text and an image.”, [...]

http://lilisworking.wordpress.com/2009/09/01/pilot-study-of-jbutton-button-location/ This topic is rather comprehensive. If a programmer wants to have a draggable button, he/she has to be cautious of several pieces of knowledge: mouseListener and mousemotionListener, Layout, Positioning.
