/**
 * 

* A ToolBar is a control which displays items horizontally * or vertically. The most common items to place within a {@code ToolBar} * are {@link Button Buttons}, {@link ToggleButton ToggleButtons} and * {@link Separator Separators}, but you are not restricted to just these, and * can insert any {@link Node} into them. *

* *

If there are too many items to fit in the ToolBar an overflow button will appear. * The overflow button allows you to select items that are not currently visible in the toolbar. *

*

* ToolBar sets focusTraversable to false. *

* *

* Example of a horizontal ToolBar with eight buttons separated with two vertical separators. *

*

 * ToolBar toolBar = new ToolBar(
 *     new Button("New"),
 *     new Button("Open"),
 *     new Button("Save"),

 *     new Button("Compile"),
 *     new Button("Run"),
 *     new Separator(true),
 *     new Button("Debug"),
 *     new Button("Profile")
 * );
