如何使用pygtk和glade显示对话框

Question

我正在尝试使用空地创建警报对话，但它不起作用。我在这里做错了什么吗？

测试.glade :

测试.py

#!/usr/bin/python

import pygtk
import gtk
import gtk.glade
import os


class app:
    def __init__( self ):

            self.builder = gtk.Builder()
        self.builder.add_from_file("test.glade")

        self.window = self.builder.get_object('window1')
            self.alert = self.builder.get_object('dialog1')

            dic = { 
              "on_hello_clicked" : self.checkon,
            }

            self.builder.connect_signals( dic )
        self.window.show_all()

    def checkon(self, widget):
                check_process = os.popen('pgrep firefox').read()
                if check_process:
                    os.popen('pkill -9 firefox')
                else:
                    self.alert.show()


addgui = app()
gtk.main()

Answer 1

我想到了两件事（假设你的缩进是正确的，而不是像上面那样）：

1.）你没有像这样调用主循环：

addgui = app()
gtk.main()

2.）你有一个拼写错误

self.alert = self.builder.get_object('dailog1')  ## dialog is spelled wrong
