ttk 标签小部件中的多个图像

Question

使用 ttk 标签，可以指定根据标签状态显示的多个图像。但我不能让它工作。这是代码。

root = Tk()

label = Label(root, image=(img0, 'active', img1))
label.pack()

当鼠标经过标签时，标签是“活动的”。因此，当鼠标经过时，显示的数字应该从 0 切换到 1。但它不起作用。 有什么帮助吗？ Python 3.5.1 / Windows Vista

Answer 1

我发现文档有点混乱，但您似乎想要 'hover' 而不是 'active'。

我不知道有任何来源解释在哪些条件下自动设置哪些状态标志。我在这里所做的是将鼠标光标放在标签上，然后通过调用label.state() 来查询状态。

Answer 2

ttk.Label 似乎不接受状态。但是，进入/退出绑定确实适用于样式配置设置。输出为绿色的 0/1。

  s.configure('zL1.TLabel', image=img1)

root = tk.Tk()
s = ttk.Style()
s.theme_use("classic") #3D/Color-alt/classic/default, Color-clam).
