JToolBar Example
The program shows a toolbar above a text area that we might imagine is used for text editing. Each tool is a button containing an ImageIcon. The buttons would normally have listeners added to them.
Tool tip text has been added to the buttons. Tool tip text shows when the user hovers over any component to which it has been added.
