Implemented Interfaces

GtkStack implements AtkImplementorIface and GtkBuildable.

Includes

#include <gtk/gtk.h>

Description

The GtkStack widget is a container which only shows one of its children at a time. In contrast to GtkNotebook, GtkStack does not provide a means for users to change the visible child. Instead, the GtkStackSwitcher widget can be used with GtkStack to provide this functionality.

Transitions between pages can be animated as slides or fades. This can be controlled with gtk_stack_set_transition_type(). These animations respect the “gtk-enable-animations” setting.

The GtkStack widget was added in GTK+ 3.10.

CSS nodes

GtkStack has a single CSS node named stack.

gtk_stack_set_homogeneous ()

void
gtk_stack_set_homogeneous (GtkStack *stack,
                           gboolean homogeneous);

Sets the GtkStack to be homogeneous or not. If it is homogeneous, the GtkStack will request the same size for all its children. If it isn't, the stack may change size when a different child becomes visible.

Since 3.16, homogeneity can be controlled separately for horizontal and vertical size, with the “hhomogeneous” and “vhomogeneous”.

Parameters

stack

a GtkStack

 

homogeneous

TRUE to make stack homogeneous

 

Since: 3.10


gtk_stack_get_homogeneous ()

gboolean
gtk_stack_get_homogeneous (GtkStack *stack);

Gets whether stack is homogeneous. See gtk_stack_set_homogeneous().

Parameters

stack

a GtkStack

 

Returns

whether stack is homogeneous.

Since: 3.10


gtk_stack_set_hhomogeneous ()

void
gtk_stack_set_hhomogeneous (GtkStack *stack,
                            gboolean hhomogeneous);

Sets the GtkStack to be horizontally homogeneous or not. If it is homogeneous, the GtkStack will request the same width for all its children. If it isn't, the stack may change width when a different child becomes visible.

Parameters

stack

a GtkStack

 

hhomogeneous

TRUE to make stack horizontally homogeneous

 

Since: 3.16


gtk_stack_get_hhomogeneous ()

gboolean
gtk_stack_get_hhomogeneous (GtkStack *stack);

                            gboolean vhomogeneous);

Sets the GtkStack to be vertically homogeneous or not. If it is homogeneous, the GtkStack will request the same height for all its children. If it isn't, the stack may change height when a different child becomes visible.

Parameters

stack

a GtkStack

 

vhomogeneous

TRUE to make stack vertically homogeneous

 

Since: 3.16


gtk_stack_get_vhomogeneous ()
