Python怎么生成带有滚动功能控件的scrollable函数

#生成Frame容器以容纳TreeView,Scrollbartree_area = Frame(paned_window)# 设定水平伸展tree_area.grid_rowconfigure(0, weight=1)# 设定垂直伸展tree_area.grid_columnconfigure(0, weight=1)# 生成TreeViewtree_view = Treeview(tree_area, show='tree', selectmode='browse')# 设定TreeView布局位置tree_view.grid(row=0, column=0, sticky='nsew')# 生成垂直滚动条scroll_ty = Scrollbar(tree_area, orient=VERTICAL, command=tree_view.yview)# 设定滚动条布局位置scroll_ty.grid(row=0, column=1, sticky=N+S)# 关联滚动动作tree_view['yscrollcommand']=scroll_ty.set# 生成水平滚动条scroll_tx = Scrollbar(tree_area, orient=HORIZONTAL, command=tree_view.xview)# 设定滚动条布局位置scroll_tx.grid(row=1, column=0, sticky=E+W)# 关联滚动动作tree_view['xscrollcommand']=scroll_tx.set

def scrollable(master, w_type, **kwargs):    # 获取SizeGrip设定内容    size_grip = kwargs.get('size_grip')    # 从关键词参数中去掉'size_grip'设定    if size_grip:        kwargs.pop('size_grip')    # 构建Frame控件    frame = Frame(master)    # 设定控件水平伸展    frame.grid_rowconfigure(0, weight=1)    # 设定控件垂直伸展    frame.grid_columnconfigure(0, weight=1)    # 构建控件    widget = w_type(frame, **kwargs)    # 设定控件布局    widget.grid(row=0, column=0, sticky='nsew')    # 构建垂直Scrollbar    scroll_y = Scrollbar(frame, orient=VERTICAL, command=widget.yview)    # 设定控件布局    scroll_y.grid(row=0, column=1, sticky=N + S)    # 绑定滚动动作    widget['yscrollcommand'] = scroll_y.set    # 构建水平Scrollbar    scroll_x = Scrollbar(frame, orient=HORIZONTAL, command=widget.xview)    # 设定控件布局    scroll_x.grid(row=1, column=0, sticky=E + W)    # 绑定滚动动作    widget['xscrollcommand'] = scroll_x.set    # 生成Sizegrip控件    if size_grip:        Sizegrip(frame).grid(row=1, column=1)    return frame,widget

tree_area, tree_view = scrollable(paned_window, Treeview, show='tree', selectmode='browse')
