Handle Box這容器跟上一篇博文中所介紹到Exapnder一樣，，只允許有一個子控件在上面。Handle Box是一個可以拿下來到控件，可以浮動到控件。咦，這功能好熟悉哦，呵呵，你想得不錯，在windows中，窗口的工具欄里面的元素是可以用鼠標拖動的。Handle Box控件能用來制作一些浮動菜單。

toolbox就是工具條

toolbar.append_item(text, tooltip_text, tooltip_private_text, icon,callback, user_data=None)
toolbar.prepend_item(text, tooltip_text, tooltip_private_text, icon,callback, user_data)

toolbar.insert_item(text, tooltip_text, tooltip_private_text, icon, callback,user_data, position)?

toolbar.append_space()
toolbar.prepend_space()
toolbar.insert_space(position)

?

toolbar.set_orientation(orientation)

orientation :ORIENTATION_HORIZONTAL or ORIENTATION_VERTICAL

toolbar.set_style(style)

style:TOOLBAR_ICONS, TOOLBAR_TEXT, TOOLBAR_BOTH

?

toolbar.set_tooltips(enable)
