有谁知道我可以改变我的ttk.progressBar的颜色吗？现在显示绿色，我很想有它的蓝色。

Does anyone know how I can change the color of my ttk.progressBar? It now shows a green color, and I would love to have it blue.

import ttk
self.progressBar = ttk.Progressbar(frame3, length=560, maximum=100, mode='determinate');
self.progressBar.place(x=-5, y=60)

推荐答案

你可以改变进度条的颜色，但它是棘手的。首先，你需要理解，如果你使用默认的主题，这是默认的主题，如果你没有在tk.style指定一个主题。然后它会将它需要的所有信息传递给操作系统，这将使用它的样式来绘制图形，忽略你传递的样式信息。意味着它将在Windows上绘制一个Window的样式绿色progressbar等等。你需要做的是将主题更改为ttk绘制的自定义主题。尝试clam风格，它是ttk允许你选择的最好看的样式之一。这里是一个工作适应摘录从我写的脚本：

you can change the color of a progressbar, but it is tricky. First, you need to understand that if you use the default theme, which is the default theme if you do not specify a theme in the tk.style. Then it will pass all the information it needs to the operating system, which will do the drawing using its style, disregarding style info you passed it. meaning it will draw a Window's style green progressbar on Windows and so on and so forth. What you need to do is change the theme to a custom one that ttk draws. Try the "clam" style, it is one of the best looking styles that ttk allows you to chose from. here is a working adapted excerpt from a script I wrote:

import Tkinter as tk
import ttk as ttk
root = tk.Tk()
frame = tk.Frame(root)
frame.grid()
s = ttk.Style()
s.theme_use('clam')
s.configure("red.Horizontal.TProgressbar", foreground='red', background='red')
ttk.Progressbar(frame, style="red.Horizontal.TProgressbar", orient="horizontal", length=600, mode="determinate", maximum=4, value=1).grid(row=1, column=1)
frame.pack()
