关于python：Tkinter在框架中加载图像

Tkinter loading images in the frame

我使用的是python 2.7，我想在tkinter框架上加载一个.gif徽标，但它始终打开两个窗口(一个空窗口，一个带徽标)。Codes：

1
2
3
4
5
6

import Tkinter

root = Toplevel()
logo = PhotoImage(file="D:\\.....\\....\\****.gif")
w1 = Label(root, compound = CENTER, image = logo).pack(side="right")
root.mainloop()

我怎么能只有一个带标志的窗口？

每个tkinter应用程序都需要一个Tk()窗口a.k.a根，其他小部件才能存在。如果不显式创建，则将隐式创建。您的空窗口是隐式创建的Tk()窗口，另一个是您创建的Toplevel()窗口。所以你需要改变这条线

1	root = Toplevel()

到

1	root = Tk()

另外，请保留您的image的参考资料。

When you add a PhotoImage or other Image object to a Tkinter widget,
you must keep your own reference to the image object. If you don’t,
the image won’t always show up.

The problem is that the Tkinter/Tk interface doesn’t handle references
to Image objects properly; the Tk widget will hold a reference to the
internal object, but Tkinter does not. When Python’s garbage collector
discards the Tkinter object, Tkinter tells Tk to release the image.
But since the image is in use by a widget, Tk doesn’t destroy it. Not
completely. It just blanks the image, making it completely
transparent…
