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张图片。但我无法让它发挥作用。这是代码。

from tkinter.ttk import *

root = Tk()

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

当鼠标经过时标签为'active'。所以当鼠标经过时，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？ Python3.5.1/WindowsVista

Answer 1

我觉得文档有点混乱，但看起来你想要 'hover' 而不是 'active'。

我不知道有任何来源解释在哪些情况下哪些状态标志会自动设置在哪些 wigdets 中。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().

查询状态

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

import tkinter as tk
import tkinter.ttk as ttk

def Limg1(*args):
  s.configure('zL1.TLabel', image=img1)

def Limg0(*args):
  s.configure('zL1.TLabel', image=img0)

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