Details

The gtk:revealer widget is a container which animates the transition of its child widget from invisible to visible. The style of transition can be controlled with a value of the gtk:revealer-transition-type enumeration. These animations respect the gtk-enable-animations setting.

CSS nodes

The gtk:revealer implementation has a single CSS node with name revealer. When styling the gtk:revealer widget using CSS, remember that it only hides its contents, not itself. That means applied margin, padding and borders will be visible even when the reveal-child property is set to false.

Accessibility

The gtk:revealer implementation uses the :group role of the gtk:accessible-role enumeration. The child widget of the gtk:revealer widget, if set, is always available in the accessibility tree, regardless of the state of the revealer widget.
