Question

我想打印标签文本（点击时FunctionResults的元素）。

import Tkinter
import os
import Func

class simpleapp_tk(Tkinter.Tk):
    def __init__(self,parent):
        Tkinter.Tk.__init__(self,parent)
        self.parent = parent
        self.initialize()
        self.Result =[]
        #self.minsize(8000,300)
        self.geometry("800x300")

    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 (1,30):
            labelVar = Tkinter.StringVar()
            labelVar.set('')
            self.labelVars.append(labelVar)
            label = Tkinter.Label(self,textvariable=labelVar,
                              anchor="w",fg="black",bg="white")

            label.bind("<1>", lambda event, text="some text": \
                          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):
        #FunctionResults is a list returned by Func.Func1
        self.FunctionResults = Func.Func1(self.entryVariable.get())
        self.FunctionResults = list(reversed(self.Result))
        for i in range (0,len( self.Result)):
            print "result",i,":", self.FunctionResults[i]
            self.labelVars[i].set(self.FunctionResults[i])
        self.entry.focus_set()
        self.entry.selection_range(0, Tkinter.END)

    def click_link(self, event, text):
        print "you clicked '%s'" % text



        #l["text"]
        #os.system("open "+textvariable+".txt")

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

相反，我得到you clicked some text。

如何编写函数click_link(self, event, text):以获取与单击标签相关联的名称？

我使用command看到了类似主题的一些答案，但我不想使用按钮。

您可以从点击的小部件中获取文本，如下所示：

def click_link(self, event, text):
    print "you clicked '%s'" % event.widget["text"]

import Tkinter
import os

class simpleapp_tk(Tkinter.Tk):
    def __init__(self,parent):
        Tkinter.Tk.__init__(self,parent)
        self.parent = parent
        self.initialize()
        self.Result =[]
        #self.minsize(8000,300)
        self.geometry("800x300")

    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 (1,30):
            labelVar = Tkinter.StringVar()
            labelVar.set('')
            self.labelVars.append(labelVar)
            label = Tkinter.Label(self,textvariable=labelVar,
                              anchor="w",fg="black",bg="white")

            label.bind("<1>", lambda event, text="some text": \
                          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
        self.Result = self.entryVariable.get()
        self.Result = list(reversed(self.Result))
        for i in range (0,len( self.Result)):
            print "result",i,":", self.Result[i]
            self.labelVars[i].set(self.Result[i])
        self.entry.focus_set()
        self.entry.selection_range(0, Tkinter.END)

    def click_link(self, event, text):
        print "you clicked '%s'" % event.widget["text"]

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

单击时返回标签文本
