public class PopOver
extends javafx.scene.control.PopupControl
```
The PopOver control provides detailed information about an owning node in a popup window. The popup window has a very lightweight appearance (no default window decorations) and an arrow pointing at the owner. Due to the nature of popup windows the PopOver will move around with the parent window when the user drags it.

The PopOver can be detached from the owning node by dragging it away from the owner. It stops displaying an arrow and starts displaying a title and a close icon.

The following image shows a popover with an accordion content node. PopOver controls are automatically resizing themselves when the content node changes its size.

For styling apply stylesheets to the root pane of the PopOver.
Example:
```
 PopOver popOver = new PopOver();
 popOver.getRoot().getStylesheets().add(...);
 
```
