我在试图操纵Tkinter的一个列表箱,但我遇到了一些麻烦。我以前把所有的东西都放在一节课上,放在一页纸上,一切都很好。我在两个不同的页面上将方法分成不同的类(一个用于显示东西,一个用于修改它们),现在我遇到了一些问题。
我得到了下面的错误AttributeError: Actions没有属性'listbox'。我假设这与继承有关,因为在我将它分成两个文件之前,它运行得很好。
这是第一个文件
from Tkinter import *
import Tkinter
import SortActions
class MakeList(Tkinter.Listbox):
def BuildMainWindow(self):
menubar = Frame(relief=RAISED,borderwidth=1)
menubar.pack()
mb_file = Menubutton(menubar,text='file')
mb_file.menu = Menu(mb_file)
mb_file.menu.add_command(label='open', command = self.BuildListbox)
mb_file.pack(side=LEFT)
mb_edit = Menubutton(menubar,text='edit')
mb_edit.menu = Menu(mb_edit)
mb_edit.pack(padx=25,side=RIGHT)
mb_file['menu'] = mb_file.menu
mb_edit['menu'] = mb_edit.menu
return
def BuildListbox(self):
self.listbox = Tkinter.Listbox()
index = SortActions.Actions()
self.listbox.bind('<<ListboxSelect>>', index.GetWindowIndex)
MoveItem = SortActions.Actions()
self.listbox.bind('<B1-Motion>', index.MoveWindowItem)
for item in ["one", "two", "three", "four"]:
self.listbox.insert(END, item)
self.listbox.insert(END, "a list entry")
self.listbox.pack()
#print self.listbox.get(0, END)
return
if __name__ == '__main__':
start = MakeList()
start.BuildMainWindow()
mainloop()还有第二个文件,那个我有问题的文件
from FileSort import MakeList
class Actions(MakeList):
#gets the current item that was clicked in the window
def GetWindowIndex(self, event):
w = event.widget
self.curIndex = int(w.curselection()[0])
#moves the current item in the window when clicked/dragged
def MoveWindowItem(self, event):
i = self.listbox.nearest(event.y) #here is where the error is occurring
print i我认为由于继承了MakeList类,所以我应该可以访问。我还试图更改它,因此我直接访问了MakeList (一个对象),但是没有错误地说"Actions实例没有.“上面说"MakeList没有属性.“
我之前发布了一些东西,但是我意外地运行了一个旧版本的代码,所以我引用了错误的错误。很抱歉你看到那条柱子了。它现在消失了

在我看来,行动没有理由出现在课堂上.
#SortActions.py
#gets the current item that was clicked in the window
def GetWindowIndex(self, event):
w = event.widget
self.curIndex = int(w.curselection()[0])
#moves the current item in the window when clicked/dragged
def MoveWindowItem(self, event):
i = self.nearest(event.y) #here is where the error is occurring
print i现在您可以使用以下操作:
...
def BuildListbox(self):
#self.listbox = Tkinter.Listbox() #??? This has no master widget ...
#Since this is already a listbox, there's no point in building another ...
self.bind('<<ListboxSelect>>', lambda e:SortActions.GetWindowIndex(self,e))
self.bind('<B1-Motion>', lambda e:SortActions.MoveWindowItem(self,e)
for item in ("one", "two", "three", "four"):
self.insert(END, item)
self.insert(END, "a list entry")
self.pack()https://stackoverflow.com/questions/14523822
