Class LabeledSkinBase<C extends Labeled>

    • Constructor Detail

      • LabeledSkinBase

        public LabeledSkinBase​(C labeled)
        Constructor for LabeledSkinBase. The Labeled must be specified, and cannot be null. At the conclusion of the constructor call, the skin will be marked as needsLayout, and will be fully configured based on the current state of the labeled. Any subsequent changes to the Labeled will be handled via listeners and applied appropriately.
        Parameters:
        labeled - The labeled that this skin should be installed onto.
    • Method Detail

      • 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.
      • computeMinWidth

        protected double computeMinWidth​(double height,
                                         double topInset,
                                         double rightInset,
                                         double bottomInset,
                                         double leftInset)
        Compute and return the minimum width of this Labeled. The minimum width is the smaller of the width of "..." and the width with the actual text. In this way, if the text width itself is smaller than the ellipsis then we should use that as the min width, otherwise the ellipsis needs to be the min width.

        We use the same calculation here regardless of whether we are talking about a single or multiline labeled. So a multiline labeled may find that the width of the "..." is as small as it will ever get.

        Overrides:
        computeMinWidth in class SkinBase<C extends Labeled>
        Parameters:
        height - The height of the Skin, in case this value might dictate the minimum width.

        bottomInset - the pixel snapped bottom inset
        leftInset - the pixel snapped left inset
        Returns:
        A double representing the minimum width of this Skin.
