Class
GtkRevealer
Description [src]
final class Gtk.Revealer : Gtk.Widget {
/* No available fields */
}A GtkRevealer animates the transition of its child from invisible to visible.
The style of transition can be controlled with
gtk_revealer_set_transition_type().
These animations respect the GtkSettings: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 GtkRevealer: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.
Constructors
gtk_revealer_new
Creates a new GtkRevealer.
