Implemented Interfaces

GtkButtonBox implements AtkImplementorIface, GtkBuildable and GtkOrientable.

Includes

#include <gtk/gtk.h>

Description

A button box should be used to provide a consistent layout of buttons throughout your application. The layout/spacing can be altered by the programmer, or if desired, by the user to alter the “feel” of a program to a small degree.

gtk_button_box_get_layout() and gtk_button_box_set_layout() retrieve and alter the method used to spread the buttons in a button box across the container, respectively.

The main purpose of GtkButtonBox is to make sure the children have all the same size. GtkButtonBox gives all children the same size, but it does allow 'outliers' to keep their own larger size.

To exempt individual children from homogeneous sizing regardless of their 'outlier' status, you can set the non-homogeneous child property.

Functions

gtk_button_box_new ()

GtkWidget *
gtk_button_box_new (GtkOrientation orientation);

Creates a new GtkButtonBox.

Parameters

orientation

the box' orientation.

 

Returns

a new GtkButtonBox.

Since 3.0


gtk_button_box_get_layout ()

GtkButtonBoxStyle
gtk_button_box_get_layout (GtkButtonBox *widget);

Retrieves the method being used to arrange the buttons in a button box.

Parameters

widget

a GtkButtonBox

 

Returns

the method used to lay out buttons in widget .


gtk_button_box_get_child_secondary ()

gboolean
gtk_button_box_get_child_secondary (GtkButtonBox *widget,
                                    GtkWidget *child);

Returns whether child should appear in a secondary group of children.

Parameters

widget

a GtkButtonBox

 

child

a child of widget

 

Returns

whether child should appear in a secondary group of children.

Since 2.4


gtk_button_box_get_child_non_homogeneous ()

gboolean
gtk_button_box_get_child_non_homogeneous
                               (GtkButtonBox *widget,
                                GtkWidget *child);

Returns whether the child is exempted from homogenous sizing.

Parameters

widget

a GtkButtonBox

 

child

a child of widget

 

Returns

TRUE if the child is not subject to homogenous sizing

Since 3.2


gtk_button_box_set_layout ()

void
gtk_button_box_set_layout (GtkButtonBox *widget,
                           GtkButtonBoxStyle layout_style);

Changes the way buttons are arranged in their container.

Parameters

widget

a GtkButtonBox

 

layout_style

the new layout style

 

gtk_button_box_set_child_secondary ()

void
gtk_button_box_set_child_secondary (GtkButtonBox *widget,
                                    GtkWidget *child,
                                    gboolean is_secondary);

Sets whether child should appear in a secondary group of children. A typical use of a secondary child is the help button in a dialog.

This group appears after the other children if the style is GTK_BUTTONBOX_START, GTK_BUTTONBOX_SPREAD or GTK_BUTTONBOX_EDGE, and before the other children if the style is GTK_BUTTONBOX_END. For horizontal button boxes, the definition of before/after depends on direction of the widget (see gtk_widget_set_direction()). If the style is GTK_BUTTONBOX_START or GTK_BUTTONBOX_END, then the secondary children are aligned at the other end of the button box from the main children. For the other styles, they appear immediately next to the main children.

Parameters

widget

a GtkButtonBox

 

child

a child of widget

 

is_secondary

if TRUE, the child appears in a secondary group of the button box.

 

gtk_button_box_set_child_non_homogeneous ()

void
gtk_button_box_set_child_non_homogeneous
                               (GtkButtonBox *widget,
                                GtkWidget *child,
                                gboolean non_homogeneous);

Sets whether the child is exempted from homogeous sizing.
