我正在制作一个只允许输入数字的条目。如果该字符不是整数,我目前坚持删除刚刚输入的字符。如果有人将“空白”替换为需要进入的内容,那将有很大帮助。
import Tkinter as tk
class Test(tk.Tk):
def __init__(self):
tk.Tk.__init__(self)
self.e = tk.Entry(self)
self.e.pack()
self.e.bind("<KeyRelease>", self.on_KeyRelease)
tk.mainloop()
def on_KeyRelease(self, event):
#Check to see if string consists of only integers
if self.e.get().isdigit() == False:
self.e.delete("BLANK", 'end')#I need to replace 0 with the last character of the string
else:
#print the string of integers
print self.e.get()
test = Test()
