Description

The GtkRevealer widget is a container which 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 “gtk-enable-animations” setting.

CSS nodes

GtkRevealer has a single CSS node with name revealer.

The GtkRevealer widget was added in GTK+ 3.10.

Functions

gtk_revealer_new ()

GtkWidget *
gtk_revealer_new (void);

Creates a new GtkRevealer.

Returns

a newly created GtkRevealer

Since: 3.10

gtk_revealer_get_reveal_child ()

gboolean
gtk_revealer_get_reveal_child (GtkRevealer *revealer);

Returns whether the child is currently revealed. See gtk_revealer_set_reveal_child().

This function returns TRUE as soon as the transition is to the revealed state is started. To learn whether the child is fully revealed (ie the transition is completed), use gtk_revealer_get_child_revealed().

Parameters

revealer

a GtkRevealer

Returns

TRUE if the child is revealed.

Since: 3.10

gtk_revealer_set_reveal_child ()

void
gtk_revealer_set_reveal_child (GtkRevealer *revealer,
                               gboolean reveal_child);

Tells the GtkRevealer to reveal or conceal its child.

The transition will be animated with the current transition type of revealer .

Parameters

revealer

Parameters

revealer

a GtkRevealer

TRUE if the child is fully revealed

Since: 3.10

gtk_revealer_get_transition_duration ()

guint
gtk_revealer_get_transition_duration (GtkRevealer *revealer);

Returns the amount of time (in milliseconds) that transitions will take.

Parameters

Returns

the transition duration

Since: 3.10

gtk_revealer_set_transition_duration ()

void
gtk_revealer_set_transition_duration (GtkRevealer *revealer,
                                      guint duration);

Sets the duration that transitions will take.

Parameters
