class: DialogPane

[96:7] extends: Pane

The DialogPane class wraps the JavaFX DialogPane, the root pane used inside a Dialog to present a structured layout with a header, content area, expandable details section, and a button bar. It is the default root node of any Dialog or Alert and uses the CSS style class dialog-pane. DialogPane extends Pane, which extends Region, giving it the full set of Region and Node CSS properties in addition to its own graphic property.
