  • Constructor Details

    • 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 Details

    • 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.
