根據 timedelta 更改文本顏色

Question

我編寫了一些計時器，並根據我在 Internet 上找到的代碼使用 tkinter 將它們可視化。 這對我來說仍然很好，但現在我需要添加一個函數。 如果全局計時器變量（timedelta_amp 等）低於 3 分鍾，我想更改計時器的字體顏色。 因為我百分百看不懂復制的代碼所以無法添加這個功能。

# importing whole module 
from tkinter import * 
# importing strftime function to 
# retrieve system's time 
from time import strftime
# importing datetime modul
from datetime import datetime, timedelta, time
# close the tkinter windwo with escape
def close_escape(event=None):
    print("escaped")
    root.destroy()
root = Tk()
root.title("Countdown Intraday Handel - Stunden Produkte") 
root.attributes("-fullscreen", False) 
root.bind("<Escape>", close_escape)
root.configure(background='orange')

Text = Label(root, font=('arial', 75, 'bold'), fg='white',bg='orange')
Text.pack()
Frame = Label(root, font=('arial', 20, 'bold'), fg='white',bg='orange')
Frame.pack()

Text1 = Label(root, font=('arial', 50, 'italic'), fg='white',bg='orange')
Text1.pack()
clock_schedulingarea = Label(root, font=('arial',50, 'bold'), fg='white',bg='orange')
clock_schedulingarea.pack()
Frame1 = Label(root, font=('arial', 20, 'bold'), fg='white',bg='orange')
Frame1.pack()

Text2 = Label(root, font=('arial', 50, 'italic'), fg='white',bg='orange')
Text2.pack()
clock_germany = Label(root, font=('arial', 50, 'bold'), fg='white', bg='orange')
clock_germany.pack()

Answer 1

您可以根據tick()內的那些timedelta設置這些計時器的顏色，如下所示：

def tick():
    ...
    if ActTimeMinutes >= "00:00" and ActTimeMinutes < "55:00":
        var1 = [SA, ActTimeHourplus1,"-", ActTimeHourplus2]
        timedelta_amp = datetime.strptime(hour_amp, "%M:%S") - datetime.strptime(ActTimeMinutes, "%M:%S")
        color_amp = 'red' if timedelta_amp.seconds < 180 else 'white' # set color_amp based on timedelta_amp
    elif ActTimeMinutes >= "55:00" and ActTimeMinutes < "59:59":
        var1 = [SA, ActTimeHourplus1,"-", ActTimeHourplus2]
        timedelta_amp = "Gate Closure"
        color_amp = 'red'  # change to other color to suit your case

    if ActTimeMinutes >= "00:00" and ActTimeMinutes < "30:00" :
        var2 = [SB, ActTimeHourplus1,"-", ActTimeHourplus2]
        timedelta_de = datetime.strptime(half, "%M:%S") - datetime.strptime(ActTimeMinutes, "%M:%S")
    elif ActTimeMinutes >= "30:00" and ActTimeMinutes < "59:59":
        var2 = [SB, ActTimeHourplus2,"-", ActTimeHourplus3]
        timedelta_de = datetime.strptime(hour, "%M:%S") - datetime.strptime(ActTimeMinutesplus30, "%M:%S")
    color_de = 'red' if timedelta_de.seconds < 180 else 'white' # set color_de based on timedelta_de
            
    var3 = [SC, ActTimeHourplus2,"-", ActTimeHourplus3]
    timedelta_sidc = datetime.strptime(hour, "%M:%S") - datetime.strptime(ActTimeMinutes, "%M:%S")
    color_sidc = 'red' if timedelta_sidc.seconds < 180 else 'white' # set color_sidc based on timedelta_sidc
    
    Text.config(text="Stunden Produkte")
    Frame.config(text="______________________________________________________________________________________________")
    
    clock_schedulingarea.config(text=timedelta_amp, fg=color_amp) # use color_amp
    Text1.config(text=var1)
    Frame1.config(text="___________________________________")
    
    clock_germany.config(text=timedelta_de, fg=color_de) # use color_de
    Text2.config(text=var2)
    Frame2.config(text="___________________________________")
    
    clock_sidc.config(text=timedelta_sidc, fg=color_sidc) # use color_sidc
    Text3.config(text=var3)
    
    clock_sidc.after(20, tick)
