[英]Tkinter Python using Enter Key, open the new window
我正在使用Python Tkinter,我有輸入文本框和確定按鈕。 現在,我已經實現了Button邏輯,例如,如果User Input = 1,則在按下OK Button之后,它將打開新窗口。 現在,對於相同的實現,不是要單擊“確定”按鈕,而是要從“鍵盤”輸入“ Enter鍵”並打開新窗口。
我不知道如何進行。
from Tkinter import *
def UserInput():
global UI_MainForm
UI_MainForm = Tk()
UI_MainForm.resizable(1,0)
UI_MainForm.geometry("300x450+0+0")
UI_MainForm.title("ChCM 1.25 Diagnostics Main Menu")
# LabelFrame to add all the Menu menu Display items
labelframe = LabelFrame(UI_MainForm,text="Please select the below options:",width=300, height=100,bd = 2)
labelframe.pack(fill="both")
labelframe.config(relief=RIDGE)
# LabelFrame to add the User input text box and buttons
labelframe1 = LabelFrame(UI_MainForm,text="User Input:",width=300, height=100,bd = 2)
labelframe1.pack(pady=8,fill="both")
labelframe1.config(relief=FLAT)
#Entry the text and display
global entrytext
entrytext = StringVar()
entry = Entry(labelframe1,textvariable=entrytext,width=35)
entry.pack(padx = 1, pady = 5)
MainMenuDisplay = [{"ID": 1,"Description": "Display Data1"},
{"ID": 2,"Description": "Display Data2"}]
for menu in MainMenuDisplay:
temp_text = '{0}. {1}'.format(menu['ID'], menu['Description'])
Label(labelframe, text=temp_text).pack(anchor = W)
ButtonOK = Button(labelframe1, text = "OK", command =OnButtonOK, width =15)
ButtonOK.pack(side = LEFT, padx = 15, pady = 15)
UI_MainForm.mainloop()
return;
def OnButtonOK():
UI_MainForm.withdraw()
Input = int(entrytext.get())
if (Input == 1):
Data1_Menu_Display();
elif (Input == 2):
Data2_Menu_Display();
else:
print "The Input is not valid"
return;
def Data1_Menu_Display():
# self.withdraw()
global top
top = Toplevel(UI_MainForm)
top.geometry("300x450+0+0")
top.title("Display Data1")
return;
def Data2_Menu_Display():
# self.withdraw()
global top
top = Toplevel(UI_MainForm)
top.geometry("300x450+0+0")
top.title("Display Data1")
return;
def Main():
UserInput()
Main()
試試這個代碼:
import tkinter
class Application:
def __init__(self, master):
self.master = master
self.master.title('GUI')
self.master.geometry('200x100')
self.label = tkinter.Label(master, text='Enter some text:')
self.label.pack()
self.entry = tkinter.Entry(master)
self.entry.bind('<Return>', self.some_action)
self.entry.pack()
self.button = tkinter.Button(master, text='Ok', command=self.some_action)
self.button.pack()
self.output = tkinter.Label(master, text='Your text is: ')
self.output.pack()
def some_action(self, event=None):
""" It's very important to remember that if you use the 'command' argument
to attach a handler function to a button, then the function cannot
take any arguments. On the other hand, if you use bind() to attach
a handler function, the function must take one argument.
To avoid this conflict, use default argument 'event=None'. """
self.output.config(text='Your text is: ' + self.entry.get())
root = tkinter.Tk()
app = Application(root)
root.mainloop()
重要的是要記住,如果使用“命令”參數將處理程序函數附加到按鈕,則該函數不能接受任何參數。 另一方面,如果使用bind()附加處理程序函數,則該函數必須帶有一個參數。 為了避免這種沖突,請在函數中使用默認參數'event = None'。
