Sometimes a simple button is just not enough. The extension allows each toolbar to have three different sizes. Using
the ExpandableToolbarItemStrategy a toolbar can have a small and a medium sized button. It can also be converted into
a stack of large Components.
- Clients need to set the property ExpandableToolbarItemStrategy.STRATEGY, an
instance of DefaultExpandableToolbarItemStrategy should be good enough for most clients.
- Clients need to use Dockables that implement ExpandableToolbarItem, for example
the ComponentDockable.
