[ Version ( since = "1.0" ) ]
public class ExpanderRow : PreferencesRow, Implementor, Actionable, Buildable
A [class@Gtk.
ListBoxRow] used to reveal widgets.
The `HdyExpanderRow` widget allows the user to reveal or hide widgets below it. It also allows the user to enable the expansion of the row, allowing to disable all that the row contains.
HdyExpanderRow as GtkBuildable
The `HdyExpanderRow` implementation of the [iface@Gtk.Buildable] interface supports adding a child as an action widget by specifying “action” as the “type” attribute of a <child> element.
It also supports adding it as a prefix widget by specifying “prefix” as the “type” attribute of a <child> element.
CSS nodes
`HdyExpanderRow` has a main CSS node with name `row`, and the `.expander` style class. It has the `.empty` style class when it contains no children.
It contains the subnodes `row.header` for its main embedded row, `list.nested` for the list it can expand, and `image.expander-row-arrow` for its arrow.
When expanded, `HdyExpanderRow` will add the `.checked-expander-row-previous-sibling` style class to its previous sibling, and remove it when retracted.
