如何在tkinter标签中合并具有不同颜色的文本 [英] How merge text in a tkinter label with different colors

问题描述

我正在用tkinter标签编写一个股票行情显示器程序，我需要将同一行文本合并为红色和绿色.我该怎么办?

I'm coding a little stocks ticker displayer program with tkinter label and I need to merge in the same line text in red color and green color. How can I do that?

如果没有，我还有其他可以使用的小部件吗?

If not, is there any other widget which I can do it with?

推荐答案

标签中不能有多种颜色.如果要使用多种颜色，请使用单行文本"小部件，或将画布与文本项一起使用.

You cannot have multiple colors in a label. If you want multiple colors, use a one-line Text widget, or use a canvas with a text item.

这是一个使用文本窗口小部件的快速而肮脏的示例.由于我从不修剪输入窗口小部件中的文本，因此它不会进行平滑滚动，不使用任何真实数据并且会浪费内存，但是它给出了大致的思路:

Here's a quick and dirty example using a text widget. It doesn't do smooth scrolling, doesn't use any real data, and leaks memory since I never trim the text in the input widget, but it gives the general idea:

import Tkinter as tk
import random

class Example(tk.Frame):
    def __init__(self, parent):
        tk.Frame.__init__(self, parent)
        self.ticker = tk.Text(height=1, wrap="none")
        self.ticker.pack(side="top", fill="x")

        self.ticker.tag_configure("up", foreground="green")
        self.ticker.tag_configure("down", foreground="red")
        self.ticker.tag_configure("event", foreground="black")

        self.data = ["AAPL", "GOOG", "MSFT"]
        self.after_idle(self.tick)

    def tick(self):
        symbol = self.data.pop(0)
        self.data.append(symbol) 

        n = random.randint(-1,1)
        tag = {-1: "down", 0: "even", 1: "up"}[n]

        self.ticker.configure(state="normal")
        self.ticker.insert("end", " %s %s" % (symbol, n), tag)
        self.ticker.see("end")
        self.ticker.configure(state="disabled")
        self.after(1000, self.tick)

if __name__ == "__main__":
    root = tk.Tk()
    Example(root).pack(fill="both", expand=True)
    root.mainloop()
