Description

A Gnome::Gtk4::Revealer animates the transition of its child from invisible to visible.

The style of transition can be controlled with .set-transition-type().

These animations respect the gtk-enable-animations defined in Gnome::Gtk4::Settings setting.

CSS nodes

Gnome::Gtk4::Revealer has a single CSS node with name revealer. When styling Gnome::Gtk4::Revealer 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

Gnome::Gtk4::Revealer uses the GTK_ACCESSIBLE_ROLE_GROUP role.

The child of Gnome::Gtk4::Revealer, if set, is always available in the accessibility tree, regardless of the state of the revealer widget.
