      @IDProperty("id")
      public class Tooltip
      extends PopupControl

  Tooltips are common UI elements which are typically used for showing additional information about a Node in the scenegraph when the Node is hovered over by the mouse. Any Node can show a tooltip. In most cases a Tooltip is created and its `text` property is modified to show plain text to the user. However, a Tooltip is able to show within it an arbitrary scenegraph of nodes - this is done by creating the scenegraph and setting it inside the Tooltip `graphic` property.

  You use the following approach to set a Tooltip on any node:

       Rectangle rect = new Rectangle(0, 0, 100, 100);
       Tooltip t = new Tooltip("A Square");
       Tooltip.install(rect, t);

  This tooltip will then participate with the typical tooltip semantics (i.e. appearing on hover, etc). Note that the Tooltip does not have to be uninstalled: it will be garbage collected when it is not referenced by any Node. It is possible to manually uninstall the tooltip, however.

  A single tooltip can be installed on multiple target nodes or multiple controls.

  Because most Tooltips are shown on UI controls, there is special API for all controls to make installing a Tooltip less verbose. The example below shows how to create a tooltip for a Button control:

       Button button = new Button("Hover Over Me");
       button.setTooltip(new Tooltip("Tooltip for Button"));

      Description copied from class: `PopupControl`
      Return the parent of this Styleable, or null if there is no parent. A PopupControl's styles are based on the popup "owner" which is the `ownerNode` or, if the ownerNode is not set, the root of the `ownerWindow's` scene. If the popup has not been shown, both ownerNode and ownerWindow will be null and `null` will be returned. Note that the PopupWindow's scene root is not returned because there is no way to guarantee that the PopupWindow's scene root would properly return the ownerNode or ownerWindow.
      Specified by:
        `getStyleableParent` in interface `Styleable`
      Overrides:
        `getStyleableParent` in class `PopupControl`
