早上好,
我正在尝试向Gtk.Entry
添加Gtk.MessageDialog
。使用以下代码,我似乎添加了Gtk.Entry
,但在对话框窗口(Python3 / Gtk3)中不可见:
#!/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
我正在寻找关于使条目可见和可编辑的线索,欢迎任何帮助。

Simple, versatile and re-usable entry dialog (sometimes referred to as input dialog) in PyGTK
答案 0 :(得分:8)
好的,现在有效,我需要在show_all()
之前run()
。我花了一些时间来弄清楚这个简单的事情。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
我这样用:
class MainWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="MyWindowTitle")
userPassword = get_user_pw(self, "Please enter your password", "Password")
