Tkinter标签文本设置为列表元素

Question

我正在构建一个gui，它从用户那里获取一个query，并运行leFunction.aFunction(query)来返回一个名为Result的列表。当用户按enter键时，我希望将每个标签上的文本设置为Result的元素。我的尝试，如下所示，只打印出最后一个标签上Result的最后一个元素…（请忍受，我是Tkinter的初学者。）

谢谢。在

import Tkinter
import os
import leFunction

class simpleapp_tk(Tkinter.Tk):
    def __init__(self,parent):
        Tkinter.Tk.__init__(self,parent)
        self.parent = parent
        self.initialize()

     def initialize(self):
        self.grid()

        self.entryVariable = Tkinter.StringVar()
        self.entry = Tkinter.Entry(self,textvariable=self.entryVariable)
        self.entry.grid(column=0,row=0,sticky='EW')
        self.entry.bind("<Return>", self.OnPressEnter)
        self.entryVariable.set(u"")

        for j in range (1,10):
            self.labelVariable = Tkinter.StringVar()
            label = Tkinter.Label(self,textvariable=self.labelVariable,
                              anchor="w",fg="black",bg="white")

            label.bind("<1>", lambda event, text="text": \
                          self.click_link(event, text))

            label.grid(column=0,row=j,columnspan=2,sticky='EW')


            self.labelVariable.set(j)

        self.grid_columnconfigure(0,weight=1)
        self.resizable(True,False)
        self.update()
        self.geometry(self.geometry())       
        self.entry.focus_set()
        self.entry.selection_range(0, Tkinter.END)

    def OnPressEnter(self,event):
        #Result is a list
        Result = leFunction.aFunction(self.entryVariable.get())

        for i in range (0,len(Result)):
            print "result",i,":",Result[i]
            self.labelVariable.set(Result[i])
        self.entry.focus_set()
        self.entry.selection_range(0, Tkinter.END)

    def click_link(self, event, text):
        print "you clicked '%s'" % text
        #os.system("open "+file)

if __name__ == "__main__":
    app = simpleapp_tk(None)
    app.title('my application')
    app.mainloop()

以下代码正常工作（前提是您的aFunction代码正常工作）：

import Tkinter
import os
import leFunction

class simpleapp_tk(Tkinter.Tk):
    def __init__(self,parent):
        Tkinter.Tk.__init__(self,parent)
        self.parent = parent
        self.initialize()

    def initialize(self):
        self.grid()

        self.entryVariable = Tkinter.StringVar()
        self.entry = Tkinter.Entry(self,textvariable=self.entryVariable)
        self.entry.grid(column=0,row=0,sticky='EW')
        self.entry.bind("<Return>", self.OnPressEnter)
        self.entryVariable.set(u"")

        self.labelVars = []
        for j in range (1,10):
            labelVar = Tkinter.StringVar()
            labelVar.set(j)
            self.labelVars.append(labelVar)
            label = Tkinter.Label(self,textvariable=labelVar,
                              anchor="w",fg="black",bg="white")

            label.bind("<1>", lambda event, text="sup": \
                          self.click_link(event, text))

            label.grid(column=0,row=j,columnspan=2,sticky='EW')

        self.grid_columnconfigure(0,weight=1)
        self.resizable(True,False)
        self.update()
        self.geometry(self.geometry())
        self.entry.focus_set()
        self.entry.selection_range(0, Tkinter.END)

    def OnPressEnter(self,event):
        #Result is a list
        Result = leFunction.aFunction(self.entryVariable.get())

        for i in range (0,len(Result)):
            print "result",i,":",Result[i]
            self.labelVars[i].set(Result[i])
        self.entry.focus_set()
        self.entry.selection_range(0, Tkinter.END)

    def click_link(self, event, text):
        print "you clicked '%s'" % text
        #os.system("open "+file)

if __name__ == "__main__":
    app = simpleapp_tk(None)
    app.title('my application')
    app.mainloop()

在每个元素上创建一个设置。然后，您可以像我一样设置此列表元素的文本：
