A component that can be used as one of the items in a Toolbar.
Each of the items on a toolbar must be a component derived from ToolbarItemComponent,
and these objects are always created by a ToolbarItemFactory - see the ToolbarItemFactory
class for further info about creating them.
The ToolbarItemComponent class is actually a button, but can be used to hold non-button
components too. To do this, set the value of isBeingUsedAsAButton to false when
calling the constructor, and override contentAreaChanged(), in which you can position
any sub-components you need to add.
To add basic buttons without writing a special subclass, have a look at the
ToolbarButton class.
