所以，我对如何在Tkinter做一些事情有了更多的好奇心。这不是必需的，但我有点想实现它。无论如何，我想要做的是当选择apSelect列表框中的一个项目时，我想创建一个或两个多列表框，然后从文件中的数据填充（为了简单起见，让我们说它来自预设列表。）除此之外，如果在apSelect中选择了不同的条目，我想让它们消失。另一件事，就是抓住那些动态列表框中选择的数据（假设它们存在）。这是使用Tkinter的代码。真正唯一重要的部分是 init _ 方法（可能是我可以设置动态生成的方法）和generate方法（我需要提取数据）。
class App:
def __init__(self, master):
dateFrame= Frame(master)
dateFrame.pack()
apSelectFrame = Frame(master)
apSelectFrame.pack()
entryFrame = Frame(master)
entryFrame.pack()
buttonFrame = Frame(master)
buttonFrame.pack()
Label(dateFrame, text="Period:").grid(row=0)
self.period = Entry(dateFrame)
self.period.grid(row=0, column=1)
Label(dateFrame, text="Year:").grid(row=1)
self.year = Entry(dateFrame)
self.year.grid(row=1, column=1)
Label(apSelectFrame, text="Select Report Type:").grid(row=0)
self.apSelect = Listbox(apSelectFrame, selectmode=SINGLE, height=3)
self.apSelect.grid(row=1)
for item in ["Artists", "Publishers", "Both"]:
self.apSelect.insert(END, item)
self.allTheThings = IntVar()
self.checkAll = Checkbutton(apSelectFrame, text="All?", variable=self.allTheThings)
self.checkAll.grid(row=1, column=1)
Label(entryFrame, text="Client Name: ").grid(row=0)
self.client = Entry(entryFrame)
self.client.grid(row=0, column=1)
Label(entryFrame, text="Publisher Name: ").grid(row=1)
self.pub = Entry(entryFrame)
self.pub.grid(row=1, column=1)
self.generateBt = Button(buttonFrame, text="Generate!", command=self.generate)
self.generateBt.pack(side=LEFT)
self.resetBt = Button(buttonFrame, text="Reset!", command=self.reset)
self.resetBt.pack(side=LEFT)
self.quitBt = Button(buttonFrame, text="Quit!", fg="red", command=buttonFrame.quit)
self.quitBt.pack(side=LEFT)

使用网格几何管理器，您可以轻松地在给定事件上显示/消失小部件，就像我在下面的示例中所做的那样。
pack有一个类似的pack_forget方法，但我想如果你的小部件在同一个地方消失/重新出现可能会有点困难，如果它不局限于静止的，专用框架。
此代码中的窗口小部件在按下按钮时显示/消失，但如果您了解如何在Tkinter中绑定事件，则此方法可用于使窗口小部件（dis）出现在您喜欢的任何事件上（请参阅更新信息的bind方法。）
import Tkinter as tk
class App(tk.Frame):
def __init__(self,master):
tk.Frame.__init__(self,master)
self.b=tk.Button(self,text='hide',command=self.hide)
self.lbl=tk.Label(self,text="This is a label you can hide")
self.b.grid(row=0,column=0)
self.lbl.grid(row=0,column=1)
def hide(self):
self.lbl.grid_forget()
self.b.config(command=self.show,text='show')
def show(self):
self.lbl.grid(row=0,column=1)
self.b.config(command=self.hide,text='hide')
if __name__ == '__main__':
root = tk.Tk()
f=App(root)
f.grid(row=0,column=0)
root.mainloop()
