获取 2 个单独的 tkinter windows 而不是浏览 3 个页面
Getting 2 separate tkinter windows instead of navigating through 3 pages
我正在尝试将我的图表从 matplot 合并到 tkinter window 中并能够浏览不同的图表。我现在已经尝试过试验并在上面绘制了一张图表。但是，我从 tkinter 得到 2 windows 而不是 1.
我已经插入了我到目前为止所做的代码：

我想显示一个来自 tkinter 的 window 来显示所有不同的页面，但是，输出给了我 2 个不同的 windows 来自 tkinter
第一个带有所有起始页面和按钮
第二个只是来自 class plot
的图表
您正在明确创建两个 windows。
第一行是：app=Tk()
第二行是 app = Trial()，因为 Trial 继承自 tk.Tk。
你得到两个 windows 因为你用 app = Tk() 创建了第一个 window，然后在你初始化 Trial 时创建了第二个 Trial 因为它继承自 Tk.事实上你不需要 app = Tk().
您希望您的绘图位于其中一页中，因此您需要将创建 matplotlib 图的所有代码移动到您的 Page class 之一中，例如PageTwo:
class PageTwo(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
label = tk.Label(self, text="Page Two")
label.pack(pady=10, padx=10)
# code for the plot
fig = plt.figure(figsize=(8, 6)) # create matplotlib figure
# add axes and plot (replace this by your matplotlib code)
ax = fig.subplots()
ax.plot(range(10))
ax.set_title('Graph Representation of repair trail', size=15)
# create the tkinter widget to display the figure
canvas = FigureCanvasTkAgg(fig, self) # here self is the widget in which you want to display the figure
canvas.get_tk_widget().pack()
toolbar = NavigationToolbar2Tk(canvas, self) # add toolbar
canvas.draw() # show content
# navigation button
button3 = ttk.Button(self, text="Back to Home",
command=lambda: controller.show_frame(StartPage))
button3.pack()
button4 = ttk.Button(self, text="Page One",
command=lambda: controller.show_frame(PageOne))
button4.pack()
