我有一个文本框小部件,其中插入了三条消息。一个是开始消息,一个是结束消息,另一个是消息,当一个'单元'已被摧毁。我希望开始和结束消息都是黑色的,但是当被插入到小部件时,将被强制显示的消息(请参阅我在代码中评论的位置)显示为红色。
我不确定如何去做这件事。我查看了How to change the color of certain words in the tkinter text widget?,这样可行,但是如果使用鼠标选择文本,它只会更改文本属性,而我希望我的文本插入那种颜色自动。
有任何建议指出我正确的方向吗?我对Tkinter
比较新。我正在使用 Python 3.6。
import tkinter as tk
import random
class SimulationWindow():
def __init__(self, master):
#Initialise Simulation Window
self.master = master
self.master.geometry('1024x768') #w,h
#Initialise Mainframe
self.mainframe()
def mainframe(self):
#Initialise Frame
self.frame = tk.Frame(self.master)
self.frame.grid_columnconfigure(0, minsize = 100)
self.frame.grid(row = 1, sticky = 'w')
self.txtb_output = tk.Text(self.frame)
self.txtb_output.config(width = 115, height = 30, wrap = tk.WORD)
self.txtb_output.grid(row = 1, column = 0, columnspan = 3, padx = 50)
btn_start = tk.Button(self.frame)
btn_start.config(text = 'Start', borderwidth = 2, padx = 2, height = 2, width = 20)
btn_start.bind('<Button-1>', self.start)
btn_start.grid(row = 2, column = 1, padx = (0,65), pady = 20)
def battle(self):
if len(self.units) == 0:
self.txtb_output.insert(tk.END, 'The battle has ended.\n')
else:
try:
destroyed = random.randint(0,4)
#I want the text here to be red
self.txtb_output.insert(tk.END, 'The unit ' + self.units[destroyed] + ' has been destroyed.\n')
self.units.remove(self.units[destroyed])
self.frame.after(5000, self.battle)
except:
self.battle()
def start(self, event):
self.units = ['battle droid', 'battle droid', 'droid tank', 'super battle droid', 'battle droid']
self.txtb_output.insert(0.0, 'The battle has begun.\n')
self.battle()
def main():
root = tk.Tk()
main_window = SimulationWindow(root)
root.mainloop()
main()
答案 0 :(得分:6)
insert()
有选项tags
,因此您可以在插入文本时协助标记(或许多标记)。
然后你必须只为这个标签指定颜色。
import tkinter as tk
root = tk.Tk()
txt = tk.Text(root)
txt.pack()
txt.tag_config('warning', background="yellow", foreground="red")
txt.insert('end', "Hello\n")
txt.insert('end', "Alert #1\n", 'warning')
txt.insert('end', "World\n")
txt.insert('end', "Alert #2\n", 'warning')
root.mainloop()
