我正在尝试布局一个基本界面，但遇到了一些麻烦。
代码：
ServerMainWindow.py
import Tkinter as tk
import ServerEditWindow as editWindow
class ServerMainWindow(tk.Toplevel):
def __init__(self, parent, title = None):
tk.Toplevel.__init__(self, parent)
#associate this window with a parent window
self.transient(parent)
if title:
self.title(title)
self.parent = parent
self.result = None
body = tk.Frame(parent)
self.initial_focus = self.listbox(body)
body.pack(fill='both')
self.buttons()
self.grab_set()
if not self.initial_focus:
self.initial_focus = self
self.protocol("WM_DELETE_WINDOW", self.cancel)
self.initial_focus.focus_set()
self.wait_window(self)
def listbox(self, parent):
"""
create the listbox that will hold the available job names.
the Listbox widget will have initial focus when the dialog
is created
"""
self.listbox = tk.Listbox(parent)
self.listbox.pack(fill='both')
for item in [1, 2, 3, 4]:
self.listbox.insert(tk.END, item)
return self.listbox
def buttons(self):
"""
add a frame to hold the buttons
Edit, Stop, and Stop all
"""
box = tk.Frame(self)
edit = tk.Button(box, text="Edit", width=10, command=self.edit)
edit.pack(side=tk.LEFT, padx=5, pady=5)
stop = tk.Button(box, text="Stop", width=10, command=self.stop)
stop.pack(side=tk.LEFT, padx=5, pady=5)
stopAll = tk.Button(box, text="Stop all", width=10, command=self.stopAll)
stopAll.pack(side=tk.LEFT, padx=5, pady=5)
box.pack()
def edit(self):
"""
callback function for the edit button
will create a new dialog window with the access list
for the selected job (from the Listbox in self.listbox)
"""
d = editWindow.ServerEditWindow(self.parent, title="other window")
def stop(self):
"""
callback function for the stop button
will stop the headless sds2 process for the selected job
(from the Listbox in self.listbox)
"""
pass
def stopAll(self):
"""
callback function for the stop all button
will stop all running headless sds2 processes
"""
pass
def cancel(self, even=None):
self.parent.focus_set()
self.destroy()
ServerEditWindow.py
import Tkinter as tk
class ServerEditWindow(tk.Toplevel):
def __init__(self, parent, title = None):
tk.Toplevel.__init__(self, parent)
#associate this window with the parent
self.transient(parent)
if title:
self.title(title)
body = tk.Frame(parent)
self.initial_focus = self.listbox(body)
body.pack(padx=5, pady=5)
self.parent = parent
self.result = None
self.newUser(body)
self.buttons()
self.grab_set()
if not self.initial_focus:
self.initial_focus = self
self.protocol("WM_DELETE_WINDOW", self.cancel)
self.initial_focus.focus_set()
self.wait_window(self)
def listbox(self, parent):
"""
create a listbox to hold the users with access to the currently selected job
"""
self.listbox = tk.Listbox(parent)
self.listbox.pack()
return self.listbox
def newUser(self, parent):
"""
a frame that holds an entry widget and a button to confirm the
addition of a user to the list of users who canaccess the job info.
"""
box = tk.Frame(parent)
self.entry = tk.Entry(box)
self.entry.pack(side = tk.TOP)
button = tk.Button(box, text="Add user", callback = self.addUser)
button.pack(side=tk.TOP)
box.pack()
def buttons(self):
"""
create the delete button for the Listbox.
"""
box = tk.Frame(self)
delete = tk.Button(box, text = "Delete user", callback=self.deleteUser)
delete.pack(side=tk.LEFT, padx=5, pady=5)
def addUser(self):
"""
add the user from self.entry to the list of users able to access
the job information.
"""
pass
def deleteUser(self):
"""
delete the user currently selected in the Listbox.
"""
pass
def cancel(self, even=None):
self.parent.focus_set()
self.destroy()
和用于测试的脚本：
#!/usr/bin/python
import ServerGUI as gui
import Tkinter as tk
root = tk.Tk()
d = gui.ServerMainWindow(root, title="main test")
root.mainloop()
问题：当从第一个对话框（在ServerMainWindow中创建）中单击Edit时，我想要第二个窗口弹出一些其他小部件。此刻我什么也没得到，没有窗户，没有错误，什么都没有。
非常感谢任何帮助。
