I'm pretty sure you didn't "head off garbage collection of the image".
Here's why: You immediately discard the MakeGui instance you create,
and it is the only thing which holds a reference to the image.
Perhaps this change will make your program work:
- MakeGui(tooltitle, filedir, filetype, plotelem, filelist)
+ gui = MakeGui(tooltitle, filedir, filetype, plotelem, filelist)
In fact, in the program below, storing the 'App' instance is what makes
the difference between a program that displays an image and one that
def __init__(self, t):
self.i = Tkinter.PhotoImage(file = "example.gif")
c = Tkinter.Canvas(t, width=16, height=16); c.pack()
c.create_image(0, 0, image = self.i, anchor=Tkinter.NW)
t = Tkinter.Tk()
# If this line is used, the program does not work
# If this line is used, the program works
a = App(t)
