Class TitledPaneSkin

    • Constructor Detail

      • TitledPaneSkin

        public TitledPaneSkin​(TitledPane control)
        Creates a new TitledPaneSkin 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<C extends Labeled>
        Overrides:
        dispose in class SkinBase<TitledPane>
      • 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<TitledPane>
      • 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<TitledPane>
        Parameters:
        x - the x position
        y - the y position
        w - the width
        h - the height
      • 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 LabeledSkinBase<TitledPane>
        Parameters:
        height - The height of the Skin, in case this value might dictate the minimum width.
        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 width of this Skin.
