TKINTER，多个窗口启动时图像混合

Question

IMAGE: --->ScreenShot of the problem

IMAGE: --->How it is meant to look:

在上面的第一个超链接中，我附上了问题的截图。

运行通过按钮连接的窗口时，从第一个窗口启动的窗口上的图像显示在第一个窗口上，而不是在刚刚打开的新窗口上。

起初我以为python可能会因为文件名相同而感到困惑。 （情况并非如此，因为我使用了具有不同文件名的稍微不同的图像。

我尝试了很多方法，但都不起作用。

这一行的正下方是第一个窗口的代码：

#----Main Menu----
root_menu = Tk()
root_menu.title("Warehouse Inventory Control System")
root_menu.configure(bg = "black")


photo = PhotoImage(file="logo.gif")
photoLabel = Label(image=photo)
photoLabel.image = photo
photoLabel.grid(row=1, column=3,columnspan = 4, sticky = N)

Title_Screen = Label(root_menu,
                     text="Welcome to the SsangYong\n Warehouse Inventory        Control System",
                     fg="grey",
                     bg="black",
                     font="Helevetica 25 bold",
                     pady = "50",
                     padx = "50",
                     ).grid(row=2, column=3)


Search_Inventory = Button(root_menu,
                          text = "Search Inventory",
                          command=Search_Inventory,
                          fg = "Blue",
                          bg = "Grey",
                          bd = 2,
                          font="Helevetica 12 bold",
                          height = 1,
                          width = 50,
                          ).grid(row=16, column=3,pady = 25,padx = 25,)

Add_Stock = Button(root_menu,
                text = "Add New Items",
                command = Add_To_Database,
                fg = "Blue",
                bg = "Grey",
                bd = 2,
                font="Helevetica 12 bold",
                height = 1,
                width = 60,
                ).grid(row=15, column=3,pady = 25,padx = 25,)

Print_Report =  Button(root_menu,
                text = "Print Stock Report",
                fg = "Blue",
                bg = "Grey",
                bd = 2,
                font="Helevetica 12 bold",
                height = 1,
                width = 70,
                ).grid(row=17, column=3,pady = 25,padx = 25,)


Help_Button = Button(root_menu,
                     text = "Help",
                     command=Help_PDF,
                     fg = "Red",
                     bg = "Black",
                     height = "1",
                     bd = "2",
                     font = "Helevetica 20 bold",
                     width = "4",
                     ).grid(row=1, column=3,rowspan = 2, sticky= NE)
root_menu.mainloop()

这是第二个窗口的代码。

Answer 1

在你的问题中，你为你的“第二个窗口”展示了这个：

def Search_Inventory():
    #---Search Window----
    root_search = Tk()
    ...
    photoLabel = Label(image=photo)

上面的代码有两个问题。首先，您正在创建Tk 的第二个实例。你不应该这样做。一个 tkinter 程序应该只有一个 Tk 的实例。如果你想要更多的窗口，你需要创建Toplevel 的实例。

第二个问题是你在哪里创建Label——你忽略了给它一个父窗口，所以它可能默认为原始窗口。您需要将最后一行更改为：

photoLabel = Label(root_search, image=photo)
