[英]Can't get contents of tkinter Entry widget in Python 3
我開始使用 Python 3,但在從 tkinter 小部件獲取值時遇到問題。 當我運行我的代碼時,我收到“名稱 edtGetMe 未定義”錯誤。 誰能看到我哪里出錯了?
from tkinter import *
# Define the class that forms my window.
class Window(Frame):
def __init__(self, master=None):
Frame.__init__(self, master)
self.master = master
self.init_window()
# Init the class.
def init_window(self):
# Place widgets on the window.
self.pack(fill=BOTH, expand=1)
# Quit button.
btnCancel = Button (self, text="Cancel", command=self.cancel_out)
btnCancel.place (x=10, y=120)
# Action button.
btnAction = Button (self, text="Set Text", command=self.action)
btnAction.place (x=100, y=120)
# The Editboxes.
edtGetMe = Entry (self)
edtSetMe = Entry (self)
edtGetMe.place (y=10, x=10, width=380, height=100)
edtSetMe.place (y=155, x=10, width=380, height=100)
def cancel_out(self):
exit()
def action (self):
# Get the entry from the GetMe box.
self.usrText = edtGetMe.get()
# Stuff it into the other box.
edtSetMe.insert(self.usrText)
def main():
root = Tk()
# Size of window.
root.geometry("400x300")
# Start Window Class.
app = Window(root)
root.mainloop()
if name == " main ": main()
首先,我將edtGetMe
替換為edtGetMe
, self.edtGetMe
也是edtSetMe
,因此可以從所有類函數訪問這些變量。 然后我在你的行self.edtSetMe.insert("insert", self.usrText)
添加了“插入”。 你也有縮進問題。
嘗試這個 :
from tkinter import *
# Define the class that forms my window.
class Window(Frame):
def __init__(self, master=None):
Frame.__init__(self, master)
self.master = master
self.init_window()
# Init the class.
def init_window(self):
# Place widgets on the window.
self.pack(fill=BOTH, expand=1)
# Quit button.
btnCancel = Button (self, text="Cancel", command=self.cancel_out)
btnCancel.place (x=10, y=120)
# Action button.
btnAction = Button (self, text="Set Text", command=self.action)
btnAction.place (x=100, y=120)
# The Editboxes.
self.edtGetMe = Entry (self)
self.edtSetMe = Entry (self)
self.edtGetMe.place (y=10, x=10, width=380, height=100)
self.edtSetMe.place (y=155, x=10, width=380, height=100)
def cancel_out(self):
exit()
def action (self):
# Get the entry from the GetMe box.
self.usrText = self.edtGetMe.get()
# Stuff it into the other box.
self.edtSetMe.insert("insert", self.usrText)
def main():
root = Tk()
# Size of window.
root.geometry("400x300")
# Start Window Class.
app = Window(root)
root.mainloop()
if __name__ == '__main__':
main()
