按钮盒(Button Boxes)可以很方便地快速布置一组按钮。它有水平和垂直两种样式。你可以用以下函数创建水平或垂直按钮盒：
GtkWidget *gtk_hbutton_box_new( void );
GtkWidget *gtk_vbutton_box_new( void );
将按钮添加到按钮盒中可以用下面这个通常的函数：
gtk_container_add (GTK_CONTAINER (button_box), child_widget);
下面的示例演示了按钮盒的不同布局设置。
#include
/* 用指定的参数创建一个按钮盒 */
GtkWidget *create_bbox( gint horizontal,
char *title,
gint spacing,
gint child_w,
gint child_h,
gint layout )
{
GtkWidget *frame;
GtkWidget *bbox;
GtkWidget *button;
frame = gtk_frame_new (title);
if (horizontal)
bbox = gtk_hbutton_box_new ();
else
bbox = gtk_vbutton_box_new ();
gtk_container_set_border_width (GTK_CONTAINER (bbox), 5);
gtk_container_add (GTK_CONTAINER (frame), bbox);
/* 设置按钮盒的外观 */
gtk_button_box_set_layout (GTK_BUTTON_BOX (bbox), layout);
gtk_box_set_spacing (GTK_BOX (bbox), spacing);
/*gtk_button_box_set_child_size (GTK_BUTTON_BOX (bbox), child_w, child_h);*/
button = gtk_button_new_from_stock (GTK_STOCK_OK);
gtk_container_add (GTK_CONTAINER (bbox), button);
button = gtk_button_new_from_stock (GTK_STOCK_CANCEL);
gtk_container_add (GTK_CONTAINER (bbox), button);
button = gtk_button_new_from_stock (GTK_STOCK_HELP);
gtk_container_add (GTK_CONTAINER (bbox), button);
return frame;
}
