顶层部件的工作，直接由窗口管理器管理的窗口。他们不必在它们上面的父widget.

你的应用程序可以使用任意数量的顶层窗口.

语法:

这里是一个简单的语法来创建这个widget:

w = Toplevel ( option, ... )

参数:

• options: 下面是这个小工具最常用的选项列表。这些选项可以作为键 - 值对以逗号分隔.

Option	Description
bg	The background color of the window.
bd	Border width in pixels; default is 0.
cursor	The cursor that appears when the mouse is in this window.
class_	Normally, text selected within a text widget is exported to be the selection in the window manager. Set exportselection=0 if you don't want that behavior.
font	The default font for text inserted into the widget.
fg	The color used for text (and bitmaps) within the widget. You can change the color for tagged regions; this option is just the default.
height	Window height.
relief	Normally, a top-level window will have no 3-d borders around it. To get a shaded border, set the bd option larger that its default value of zero, and set the relief option to one of the constants.
width	The desired width of the window.
