    - #### ToolBarSkin

          public ToolBarSkin​(ToolBar control)

      Creates a new ToolBarSkin instance, installing the necessary child nodes into the Control `children` list, as well as the necessary input mappings for handling key, mouse, etc events.
      Parameters:
        `control` - The control that this skin should be installed onto.

  - ### Method Detail

    - #### dispose

          public void dispose()

      Called by a Skinnable when the Skin is replaced on the Skinnable. This method allows a Skin to implement any logic necessary to clean up itself after the Skin is no longer needed. It may be used to release native resources. The methods `Skin.getSkinnable()` and `Skin.getNode()` should return null following a call to dispose. Calling dispose twice has no effect.
      Specified by:
        `dispose` in interface `Skin<ToolBar>`
      Overrides:
        `dispose` in class `SkinBase<ToolBar>`
