Tkinter 中按钮的颜色

Question

我正在使用 Tkinter 制作一个小的测试软件。我想把一个按钮涂成红色，当你点击它时，它变成了绿色。似乎有人问过类似的问题，但没有一个有任何区别。root = tkinter.Tk()root.title('Test Software')root.resizable(width = False, height = False)root.geometry("300x300")HandleBarButton = ttk.Button(text = "Handle Bars", bg = "red", command = handleBarCommand)HandleBarButton.grid(row = 0, column = 0)parkingStallButton = ttk.Button(text = "Parking Stalls", bg = "red", command = parkingStallsCommand)parkingStallButton.grid(row = 0, column = 1)toiletButton = ttk.Button(text = "Toilets", bg = "red", command = toiletsCommand)toiletButton.grid(row = 0, column = 2)doorsButton = ttk.Button(text = "Doors", bg = "red", command = doorsCommand)doorsButton.grid(row = 0, column = 3)我有上面定义的命令，但这对我的问题不是必需的。当我运行它时，它给出了错误：_tkinter.TclError: unknown option "-bg"这有什么帮助吗？谢谢。
