gtk3 - Python/Gtk3 : How to add a Gtk. 进入 Gtk.MessageDialog？

Question

早上好，

我正在尝试添加 Gtk.Entry到 Gtk.MessageDialog .使用以下代码，我似乎添加了 Gtk.Entry但它在对话窗口中不可见 (Python3/Gtk3) :

#!/usr/bin/python3

from gi.repository import Gtk

def get_user_pw(parent, message, default=''):
    dialogWindow = Gtk.MessageDialog(parent,
                          Gtk.DialogFlags.MODAL | Gtk.DialogFlags.DESTROY_WITH_PARENT,
                          Gtk.MessageType.QUESTION,
                          Gtk.ButtonsType.OK_CANCEL,
                          message)

    dialogBox = dialogWindow.get_content_area()
    userEntry = Gtk.Entry()
    userEntry.set_visibility(False)
    userEntry.set_invisible_char("*")
    userEntry.set_size_request(250,0)
    userEntry.set_text("Test")
    dialogBox.pack_end(userEntry, False, False, 0)
    #dialogWindow.vbox.pack_start(userEntry, False, False, 0)

    response = dialogWindow.run()
    text = userEntry.get_text() 
    dialogWindow.destroy()
    if response == Gtk.ResponseType.OK:
        return text
    else:
        return None

class MainWindow(Gtk.Window):

    def __init__(self):

        Gtk.Window.__init__(self, title="MyWindowTitle")

        userPassphrase = get_user_pw(self, "SSH key passphrase")
        print("User passphrase: " + userPassphrase)

此代码打印:

User passphrase: Test

我正在寻找有关使条目可见和可编辑的线索，欢迎任何帮助。

好的，现在可以使用了，我需要 show_all()之前 run() .我花了一些时间才弄明白这个简单的事情。调试代码是:

def get_user_pw(parent, message, title=''):
    # Returns user input as a string or None
    # If user does not input text it returns None, NOT AN EMPTY STRING.
    dialogWindow = Gtk.MessageDialog(parent,
                          Gtk.DialogFlags.MODAL | Gtk.DialogFlags.DESTROY_WITH_PARENT,
                          Gtk.MessageType.QUESTION,
                          Gtk.ButtonsType.OK_CANCEL,
                          message)

    dialogWindow.set_title(title)

    dialogBox = dialogWindow.get_content_area()
    userEntry = Gtk.Entry()
    userEntry.set_visibility(False)
    userEntry.set_invisible_char("*")
    userEntry.set_size_request(250,0)
    dialogBox.pack_end(userEntry, False, False, 0)

    dialogWindow.show_all()
    response = dialogWindow.run()
    text = userEntry.get_text() 
    dialogWindow.destroy()
    if (response == Gtk.ResponseType.OK) and (text != ''):
        return text
    else:
        return None

我像这样使用它:

class MainWindow(Gtk.Window):

    def __init__(self):
        Gtk.Window.__init__(self, title="MyWindowTitle")
        userPassword = get_user_pw(self, "Please enter your password", "Password")
