如何在tkinter应用程序中删除特定行标签小部件

问题描述：

我无法找到一种方法在我的共享应用程序中删除一行小部件。我目前正在试验grid_forget方法;然而这只是删除了对象的最后一个实例。我的目标是能够输入与我想要删除的行相关的代码，然后它将在标签列表中找到代码并删除整行，然后行将自动调整并向上移动以填充任何行白色空间。说实话，我不确定这是否可以用tkinter和python实现，但我只是一个初学者，所以不知道。缺失的代码看起来是这样的：如何在tkinter应用程序中删除特定行标签小部件

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()

我遇到的问题是，self.label1…label10重复了多行，所以忘记self.label1只会忘记最近的条目。这意味着我需要找到在第x行忘记self.label1至self.label10的方法，其中x等于我想要删除/忘记的行号。

下面我的不完整但工作程序的完整代码。如果任何人复制并粘贴代码进行测试，澳大利亚在我们的股票市场上使用3个字母代码，即。 STO，NAB，CBA。 etc ...

我建议建立大量框架，以保持标签的，所以你可以删除整个框架。 –

感谢您的建议 - 我无法真正理解这将如何工作，但我不认为这是可行的，因为我已经将框架设置在具有滚动条的画布内，因此您可以添加尽可能多的行只要你愿意，画布就会展开以迎合它。我看到它的方式，创建大量的帧将限制我创建多少帧的条目。 – SGB

是的，但您可以根据需要创建任意数量的帧。 –

答

这是一些代码可能会帮助你。要创建一个新的帧调用add_frame()，然后删除一个帧调用framelist[whatevernumbertheframeis].destroy()。若要在框架中创建小部件，请转至Label(framelist[framenumber], text="etc.")并在最后创建的框架中创建小部件，然后执行Label(framelist[-1], text="etc.")。希望这可以帮助！

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()

现在，因为我没有你的模块，我不能这样做很好，但这里是你如何能做到它的一部分的例子。

P.S还有在代码中的多个错误...

我的大脑几乎在融化，试图将它适应到我的程序中。我感谢你的帮助，但我似乎无法弄清楚它是如何工作到我的应用程序。我已经将我的标签更改为'self.label2 = Label（self.framelist [i]，textvariable = self.code_main）'并添加了'self.add_frame（）'，但它有点凌乱和令人费解的atm ...如果可以的话提供关于如何实现您的代码的任何进一步的指导，我将不胜感激。 – SGB

@SGB K.我会尽力做到明天，但它可能不完美... –

非常感谢。我仍然试图让我的头脑围绕这么多新的编程概念，有时它可能有点压倒性。如果我可以采取另一种方法来解决标签删除问题（或者添加/删除一般记录），那么您认为值得研究，我很乐意提供任何建议。再次感谢。 – SGB
