ondestroy 不执行回调函数
我正在使用 python gtk+ 和glade 开发一个应用程序。我的空地文件格式是 gtk-builder。我有两个窗口 - 一个主窗口和一个登录窗口。在 __ init __ () 中,我运行登录对话框窗口,这样我就可以确保焦点不会切换到主窗口,直到用户发出 OK 信号登录窗口。使用以下代码完成此操作后,用户必须单击标题栏上的 [x] 两次才能退出应用程序。当我使用 loginWindow.show() 而不是 run() 时,它工作得很好,但焦点问题出现在那里。我该如何解决这个问题?
import sys
try:
import pygtk
pygtk.require("2.8")
except:
pass
try:
import gtk
except:
sys.exit(1)
class netChat:
def __init__(self):
self.builder = gtk.Builder()
self.builder.add_from_file("netchat.glade")
self.builder.connect_signals(self)
self.loginWindow = self.builder.get_object('loginWindow')
self.mainWindow = self.builder.get_object('mainWindow')
self.message = self.builder.get_object('message')
self.timeLine = self.builder.get_object('timeLine')
self.loginWindow.run()
def onSend(self, widget):
text = self.message.get_text()
myBuffer = self.timeLine.get_buffer()
myBuffer.insert_at_cursor(' '+text+'\n')
self.message.set_text('')
print "on Send"
def mainQuit(self, widget):
print "Quiting, goodbye!"
sys.exit(0)
def loginQuit(self, widget):
print "Login Quit, goodbye!"
sys.exit(1)
if __name__ == "__main__":
myChat = netChat()
gtk.main()
我也尝试为两个窗口设置相同的 mainQuit() 回调。但这没有任何区别。感谢您的任何帮助。
I'm developing an application using python gtk+ and glade. My glade file format is gtk-builder. I've two windows in it - one main window and one login window. Inside __ init __ () I run the login dialog window, so that I can make sure the focus will not be switched to the main window until the user emits OK signal from the login window. When this is done using the following code, the user has to click twice on the [x] on the titlebar, to quit the application. When I use loginWindow.show() rather than the run(), it works perfect, but the focus issue arises there. How can I fix this issue?

pygtk.require("2.8")

class netChat:
def __init__(self):
self.builder = gtk.Builder()
self.builder.add_from_file("netchat.glade")
self.builder.connect_signals(self)
self.loginWindow = self.builder.get_object('loginWindow')
self.mainWindow = self.builder.get_object('mainWindow')
self.message = self.builder.get_object('message')
self.timeLine = self.builder.get_object('timeLine')
self.loginWindow.run()
def onSend(self, widget):
text = self.message.get_text()
myBuffer = self.timeLine.get_buffer()
myBuffer.insert_at_cursor(' '+text+'\n')
self.message.set_text('')
print "on Send"
def mainQuit(self, widget):
print "Quiting, goodbye!"
sys.exit(0)
def loginQuit(self, widget):
print "Login Quit, goodbye!"
sys.exit(1)
if __name__ == "__main__":
myChat = netChat()
gtk.main()
I tried setting the same mainQuit() callback for both of the windows too. But that didn't make any difference. Thanks for any help.

您似乎遇到了重入问题。您可能正在通过登录对话框中“确定”按钮的 onClick 运行主窗口。
也许您多次调用
gtk.main()
?很难猜测,因为您的代码不完整。
It looks like you have a reentry issue. Probably you are running the main window from the onClick of the "ok" button in the login dialog.
Maybe you are calling
gtk.main()
several times?It is difficult to guess, since your code is not complete.
