      • 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<TreeCell<T>>
      • updateChildren

        protected void updateChildren​()
        Updates the children managed by LabeledSkinBase, which can be the Labeled graphic and/or a Text node. Only those nodes which actually must be used are used. For example, with a ContentDisplay of GRAPHIC_ONLY the text node is not added, and with a ContentDisplay of TEXT_ONLY, the graphic is not added.
        Overrides:
        updateChildren in class LabeledSkinBase<TreeCell<T>>
      • layoutChildren

        protected void layoutChildren​(double x,
                                      double y,
                                      double w,
                                      double h)
        The Layout algorithm works like this: - Get the labeled w/h, graphic w/h, text w/h - Compute content w/h based on graphicVPos, graphicHPos, graphicTextGap, and graphic w/h and text w/h - (Note that the text content has been pre-truncated where necessary) - compute content x/y based on content w/h and labeled w/h and the labeled's hpos and vpos - position the graphic and text
        Overrides:
        layoutChildren in class LabeledSkinBase<TreeCell<T>>
        Parameters:
        x - the x position
        y - the y position
        w - the width
        h - the 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<TreeCell<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.
      • computePrefHeight

        protected double computePrefHeight​(double width,
                                           double topInset,
                                           double rightInset,
