如何停止在Tkinter EntryBox上選擇文本的選項卡

Question

我在AutocompleteEntry上使用此代碼可用於爲Tkinter附帶的Entry小部件創建子類。

在第57行中，handle_keyrelease（）函數似乎處理TE AutocompleteEntry如何響應特定按鍵：

def handle_keyrelease(self, event): 
    """event handler for the keyrelease event on this widget""" 
    if event.keysym == "BackSpace": 
     self.delete(self.index(Tkinter.INSERT), Tkinter.END) 
     self.position = self.index(Tkinter.END) 
    if event.keysym == "Left": 
     if self.position < self.index(Tkinter.END): # delete the selection 
      self.delete(self.position, Tkinter.END) 
     else: 
      self.position = self.position-1 # delete one character 
      self.delete(self.position, Tkinter.END) 
    if event.keysym == "Right": 
     self.position = self.index(Tkinter.END) # go to end (no selection) 
    if event.keysym == "Down": 
     self.autocomplete(1) # cycle to next hit 
    if event.keysym == "Up": 
     self.autocomplete(-1) # cycle to previous hit 
    # perform normal autocomplete if event is a single key or an umlaut 
    if len(event.keysym) == 1 or event.keysym in tkinter_umlauts: 
     self.autocomplete() 

，右按鍵被設置爲做我想做的，完成的第一個字我輸入並跳到它的結尾，我的問題是以下，我想要更改Tab鍵的右鍵，但我的輸入框上的Tab鍵選擇所有的文本，我找不到方法來更改此行爲，有沒有辦法？

這裏是我的代碼，我創造我的輸入框，以供參考的一部分，遺憾的是：

from tkinter import * 
import entryautocomplete as eac 

if __name__ == '__main__': 
    # create Tkinter window 
    master = Tk() 
    # change the window name 
    master.title('Jarbas') 
    # avoids resizing of the window 
    master.resizable(width=False, height=False) 
    # center top the window on my computer 
    master.geometry('+400+0') 
    # adds an icon 
    img = Image("photo", file="jarbas.png") 
    master.tk.call('wm', 'iconphoto', master._w, img) 

    # create the entry frame 
    uinput = Frame(master) 
    # create the other frame 
    resultado = LabelFrame(
     master, text='###', labelanchor='n', font='arial 12', relief='flat') 

    # places the two frames on the window 
    uinput.grid() 
    resultado.grid() 

    # place a label on the Entry frame, picked random from a list 
    Label(uinput, text=ola[randint(0, len(ola) - 1)]).grid() 
    # Creates the entry 
    texto = eac.AutocompleteEntry(
     uinput, font='arial 14 bold', width='60', takefocus='off') 
    texto.grid(padx=5, pady=4) 
    texto.set_completion_list(comandos) 

    # calls the function 'get_input' once you press Return on the Entry box 
    # the function reads what is typed and does what it should do 
    texto.bind('<Return>', get_input) 

    # tkinter main loop 
    mainloop() 

Answer 1

有關進一步的參考，基於this question，我設法得到它的工作通過簡單地添加bind到標籤調用一個函數，return小號break，就像這樣：

def tab_handler(event): 
    return 'break' 

entry.bind('<Tab>', tab_handler) 

，只是改變了if event.keysym == "Right":上EntryAutoComplete文件if event.keysym == "Tab":

工作很好。
