如何在tkinter應用程序中刪除特定行標籤小部件

Question

我無法找到一種方法在我的共享應用程序中刪除一行小部件。我目前正在試驗grid_forget方法;然而這只是刪除了對象的最後一個實例。我的目標是能夠輸入與我想要刪除的行相關的代碼，然後它將在標籤列表中找到代碼並刪除整行，然後行將自動調整並向上移動以填充任何行白色空間。說實話，我不確定這是否可以用tkinter和python實現，但我只是一個初學者，所以不知道。缺失的代碼看起來是這樣的：

def delete(self, event = None): 
    if self.code_entry_delete.get() in self.code_list: 
     self.label1.grid_forget() 
     self.label2.grid_forget() 
     … 
     self.label10.grid_forget() 

我遇到的問題是，self.label1…label10重複了多行，所以忘記self.label1只會忘記最近的條目。這意味着我需要找到在第x行忘記self.label1至self.label10的方法，其中x等於我想要刪除/忘記的行號。

下面我的不完整但工作程序的完整代碼。如果任何人複製並粘貼代碼進行測試，澳大利亞在我們的股票市場上使用3個字母代碼，即。 STO，NAB，CBA。 etc ...

Answer 1

這是一些代碼可能會幫助你。要創建一個新的幀調用add_frame()，然後刪除一個幀調用framelist[whatevernumbertheframeis].destroy()。 若要在框架中創建小部件，請轉至Label(framelist[framenumber], text="etc.")並在最後創建的框架中創建小部件，然後執行Label(framelist[-1], text="etc.")。希望這可以幫助！

from Tkinter import * 
framelist=[] 
frames=1 
def add_frame(): 
    global frames 
    framelist.append(Frame(root)) 
    framelist[-1].grid() 
    frames+=1 

root=Tk() 
for i in range(20): 
    add_frame() 
    Label(framelist[i], text="Frame %i" % (i)).grid() 
framelist[6].destroy() 
root.mainloop() 

現在，因爲我沒有你的模塊，我不能這樣做很好，但這裏是你如何能做到它的一部分的例子。

P.S還有在代碼中的多個錯誤...
