按钮盒 Button Boxes

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:

//创建 水平排列 的一组按钮box控件:
GtkWidget *gtk_hbutton_box_new( void );

//创建 垂直排列 的一组按钮box控件:
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 <gtk/gtk.h>

/* 用指定的参数创建一个按钮盒 */
