ExpanderRow

class ExpanderRow(**properties: Any)

Superclasses: PreferencesRow, ListBoxRow, Widget, InitiallyUnowned, Object

Implemented Interfaces: Accessible, Actionable, Buildable, ConstraintTarget

A ListBoxRow used to reveal widgets.

The AdwExpanderRow 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.

AdwExpanderRow as GtkBuildable

The AdwExpanderRow implementation of the Buildable interface supports adding a child as an suffix widget by specifying “suffix” 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

AdwExpanderRow 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.

Style classes

AdwExpanderRow can use the `. <style-classes.html#property-rows>`__ style class to emphasize the row subtitle instead of the row title, which is useful for displaying read-only properties.

When used together with the .monospace style class, only the subtitle becomes monospace, not the title or any extra widgets.
