public class Revealer extends Widget
A `GtkRevealer` animates the transition of its child from invisible to visible.

The style of transition can be controlled with
[method@Gtk.Revealer.set_transition_type].

These animations respect the [property@Gtk.Settings:gtk-enable-animations]
setting.

# CSS nodes

`GtkRevealer` has a single CSS node with name revealer.
When styling `GtkRevealer` using CSS, remember that it only hides its contents,
not itself. That means applied margin, padding and borders will be visible even
when the [property@Gtk.Revealer:reveal-child] property is set to %FALSE.

# Accessibility

`GtkRevealer` uses the %GTK_ACCESSIBLE_ROLE_GROUP role.

The child of `GtkRevealer`, if set, is always available in the accessibility
tree, regardless of the state of the revealer widget.

      the child is fully revealed (ie the transition is completed),
      use [method@Gtk.Revealer.get_child_revealed].
      Returns:
      %TRUE if the child is revealed.

    • getTransitionDuration

      public int getTransitionDuration()
      Returns the amount of time (in milliseconds) that
      transitions will take.
      Returns:
