python tkinter界面如何创建一个新的显示txt文件
python tkinter interface how to create a new to show txt file
我构建了一个代码,它接受 python 用户输入并在按下应用时将其插入到文本文件中,如下图所示
当用户插入新文本时,文本文件将始终更新,如何在应用旁边创建一个新按钮以向用户显示最新的文本文件
并希望防止输入相同的文本
例如,如果文本文件有一个 (go) 程序不要再次输入 (go)
这是我的代码
root = Tk()
ivn = StringVar()
inputVarName = Entry(root, textvariable=str(ivn))
ivn.set(str("text1"))
inputVarName.grid(row=0, column=0)
ivn2 = StringVar()
inputVarName2 = Entry(root, textvariable=str(ivn2))
ivn2.set(str("text2"))
inputVarName2.grid(row=1, column=0)
def writetofile():
content_list = [ivn.get(), ivn2.get()]
print("\n".join(content_list))
with open("help.txt", "a") as f:
for item in content_list:
f.write("%s\n" % item)
applyButton = Button(root, text="Apply", command=writetofile)
applyButton.grid(row=2, column=1)
root.mainloop()
为了防止用户插入相同的文本,只需清空这两个条目,您可以在保存到文件之前检查条目是否不为空。
您可以使用顶级 window 来显示文件内容。
检查以下示例:
from tkinter import Tk, Toplevel, Button, Entry, StringVar, Text, DISABLED, END, W, E
import tkinter.ttk as ttk
import tkMessageBox
root = Tk()
ivn = StringVar()
inputVarName = Entry(root, textvariable=str(ivn))
ivn.set(str("text1"))
inputVarName.grid(row=0, column=0,columnspan=2)
ivn2 = StringVar()
inputVarName2 = Entry(root, textvariable=str(ivn2))
ivn2.set(str("text2"))
inputVarName2.grid(row=1, column=0,columnspan=2)
def writetofile():
content_list = [ivn.get(), ivn2.get()]
if any(content_list):
print("\n".join(content_list))
with open("help.txt", 'r+') as inFile:
for item in content_list:
if ("%s\n" % item).encode('UTF-8') in inFile:
tkMessageBox.showwarning("Warning", "'%s': Already exists!" % item)
return
with open("help.txt", "a") as f:
for item in content_list:
f.write( ("%s\n" % item).encode('UTF-8'))
ivn.set('')
ivn2.set('')
def showfile():
top = Toplevel()
top.title("help.txt")
textArea = Text(top)
scrollbar = ttk.Scrollbar(top, command=textArea.yview)
scrollbar.grid(row=0, column=1, sticky='nsew')
textArea['yscrollcommand'] = scrollbar.set
with open("help.txt", "r") as infile:
textArea.insert(END, infile.read())
textArea.grid(row=0, column=0)
textArea.config(state=DISABLED)
applyButton = Button(root, text="Apply", command=writetofile)
applyButton.grid(row=2, column=0, sticky=W+E)
showButton = Button(root, text="Show", command=showfile)
showButton.grid(row=2, column=1, sticky=W+E)
root.mainloop()

您可以使用 tkFileDialog.askopenfilename
请求用户 select 一个文件:
from Tkinter import Tk
import Tkinter, Tkconstants, tkFileDialog
root = Tk()
root.filename = tkFileDialog.askopenfilename(initialdir = "/",title = "Select file",filetypes = (("text files","*.txt"),("all files","*.*")))
print (root.filename)
我正在尝试相同的操作,但只有一个输出
import tkinter.ttk as ttk
import tkMessageBox
root = Tk()
root.geometry("500x300")
root.title("The Gatway company")
ivn = StringVar()
inputVarName = Entry(root, textvariable=str(ivn))
ivn.set(str("text1"))
inputVarName.grid(row=0, column=0,columnspan=2)
def writetofile():
content_list = [ivn.get()]
if any(content_list):
with open("help.txt", 'r+') as inFile:
for item in content_list:
if ("%s\n" % item).encode('UTF-8') in inFile:
tkMessageBox.showwarning("Warning", "'%s': Already exists!" % item)
return
with open("help.txt", "a") as f:
for item in content_list:
f.write( ("%s\n" % item).encode('UTF-8'))
ivn.set('')
def showfile():
top = Toplevel()
top.title("help.txt")
textArea = Text(top)
scrollbar = ttk.Scrollbar(top, command=textArea.yview)
scrollbar.grid(row=0, column=1, sticky='nsew')
textArea['yscrollcommand'] = scrollbar.set
with open("help.txt", "r") as infile:
textArea.insert(END, infile.read())
textArea.grid(row=0, column=0)
textArea.config(state=DISABLED)
applyButton = Button(root, text="Apply", command=writetofile)
applyButton.grid(row=2, column=0, sticky=W+E)
applyButton.config( height = 5, width = 10 )
showButton = Button(root, text="Show", command=showfile)
showButton.grid(row=2, column=1, sticky=W+E)
showButton.config( height = 5, width = 10 )
root.mainloop()
它与您的代码相同,但对于一个条目,我正在考虑以用户像文件请求者一样选择 help.txt 文件的方式对其进行编辑。
