我有下面的脚本，它使用Tkinter。
class MeshPlotter(tk.Frame):
def __init__(self, parent, filename):
super().__init__(self, parent)
self.labels = {
'Cell': 'Cell:',
'Cellborn': 'Cell born:',
'Surface': 'Surface:',
'Material': 'Material:',
'Universe': 'Universe:',
'Energy': 'Energy in:',
'Energyout': 'Energy out:'
}
self.filterBoxes = {}
# Read data from source or leakage fraction file
self.get_file_data(filename)
# Set up top-level window
top = self.winfo_toplevel()
top.title('Mesh Tally Plotter: ' + filename)
top.rowconfigure(0, weight=1)
top.columnconfigure(0, weight=1)
self.grid(sticky=tk.W+tk.N)
# Create widgets and draw to screen
self.create_widgets()
self.update()
当我运行它时，我得到以下错误：
app = MeshPlotter(root, filename)
.
.
.
self.tk = master.tk
AttributeError: 'MeshPlotter' object has no attribute 'tk'
完全错误：
