在Tkinter.Canvas中更改特定角色的颜色

Question

I'm trying to change specific characters color in Tkinter.Canvas... I search on net for a solution and nothing.

txt1 = canvasFrame.create_text(500,100, text = "redblue", font = "Calibri, 30", fill = "#4587de")

The actual color is blue, I need to paint the 'red string' with red color and the 'blue string' still blue.

There is a way to do this?

Answer 1

The canvas doesn't allow to use multiple colors for one string object. You will need to use two create_text commands, one for each color. That also means you'll have to calculate the proper spacing and alignment of the two strings on the canvas so that it looks like one string.

The canvas isn't a very good solution if you need to color individual characters. If you can, you might want to switch to using a text widget.

Answer 2

One can put a text widget (with colored text) on a canvas.

from tkinter import *
root = Tk()
canvas = Canvas(root)
canvas.pack()
text = Text(canvas, height=1, width=20)
text.insert('end', 'red green blue')
text['state'] = DISABLED  # read only
canvas.create_window(100, 20, anchor='nw', window=text)
root.mainloop()
