    - #### ListCellSkin

          public ListCellSkin​(ListCell<T> control)

      Creates a new ListCellSkin 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<T>`
      Overrides:
        `dispose` in class `SkinBase<ListCell<T>>`

    - #### computePrefWidth

          protected double computePrefWidth​(double height,
                                            double topInset,
                                            double rightInset,
                                            double bottomInset,
                                            double leftInset)

      Calculates the preferred width of this `SkinBase`. The default implementation calculates this width as the width of the area occupied by its managed children when they are positioned at their current positions at their preferred widths.
      Overrides:
        `computePrefWidth` in class `LabeledSkinBase<ListCell<T>>`
      Parameters:
        `height` - the height that should be used if preferred width depends on it
        `topInset` - the pixel snapped top inset
        `rightInset` - the pixel snapped right inset
        `bottomInset` - the pixel snapped bottom inset
        `leftInset` - the pixel snapped left inset
      Returns:
        the calculated preferred width

    - #### computePrefHeight

          protected double computePrefHeight​(double width,
                                             double topInset,
                                             double rightInset,
                                             double bottomInset,
                                             double leftInset)

      Calculates the preferred height of this `SkinBase`. The default implementation calculates this height as the height of the area occupied by its managed children when they are positioned at their current positions at their preferred heights.
      Overrides:
        `computePrefHeight` in class `LabeledSkinBase<ListCell<T>>`
      Parameters:
        `width` - the width that should be used if preferred height depends on it
        `topInset` - the pixel snapped top inset
        `rightInset` - the pixel snapped right inset
        `bottomInset` - the pixel snapped bottom inset
        `leftInset` - the pixel snapped left inset
      Returns:
        the calculated preferred height

    - #### computeMinHeight

          protected double computeMinHeight​(double width,
                                            double topInset,
                                            double rightInset,
                                            double bottomInset,
                                            double leftInset)

      Computes the minimum allowable height of the Skin, based on the provided width.
      Overrides:
        `computeMinHeight` in class `LabeledSkinBase<ListCell<T>>`
      Parameters:
        `width` - The width of the Skin, in case this value might dictate the minimum height.
        `topInset` - the pixel snapped top inset
        `rightInset` - the pixel snapped right inset
        `bottomInset` - the pixel snapped bottom inset
        `leftInset` - the pixel snapped left inset
      Returns:
        A double representing the minimum height of this Skin.

    - #### computeMaxHeight

          protected double computeMaxHeight​(double width,
                                            double topInset,
                                            double rightInset,
                                            double bottomInset,
                                            double leftInset)

      Computes the maximum allowable height of the Skin, based on the provided width.
      Overrides:
        `computeMaxHeight` in class `LabeledSkinBase<ListCell<T>>`
      Parameters:
        `width` - The width of the Skin, in case this value might dictate the maximum height.
        `topInset` - the pixel snapped top inset
        `rightInset` - the pixel snapped right inset
        `bottomInset` - the pixel snapped bottom inset
        `leftInset` - the pixel snapped left inset
      Returns:
        A double representing the maximum height of this Skin.
