Python/Gtk3 : How to add a Gtk.Entry to a Gtk.MessageDialog?

Question

Good morning,

I'm trying to add a Gtk.Entry to a Gtk.MessageDialog. With the following code it seems that I added the Gtk.Entry but it's not visible on the dialog window (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)

This code prints :

User passphrase: Test

I'm looking for clues about making the entry visible and editable, any help is welcome.

I couldn't do that at the time. I didn't have enough reputation points I think. Now it's done. — Jean

Ok it works now, I needed to show_all() before run(). It took me some times to figure out this simple thing. Debugged code is :

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

I use it like this :

class MainWindow(Gtk.Window):

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

This may be going about it the hard way if this is just to run a sudo command - you could simply call

os.system('pkexec (yourcommand)')
