在GTK3中打开子窗口

当Canonical-快速设置一个新项目时,它有"关于对话框的以下行":

    self.AboutDialog = AboutNewAppDialog

我编辑了glade中的菜单项,并将以下代码添加到主窗口的python代码中:

    self.menuabout = self.builder.get_object("menuabout")

   def on_menuabout_activate(self, menuitem, data=None):
        print("About activated")
        self.response = self.AboutDialog.run()
        self.AboutDialog.hide()

但这会产生错误:

   self.response = self.AboutDialog.run()
   TypeError: run() takes exactly 1 argument (0 given)

我也在使用本教程,该教程使用类似的语法:http://gnipsel.com/glade/glade02b.html

当我将Gtk.Dialog放入括号时程序崩溃:

   self.response = self.AboutDialog.run(Gtk.Dialog)

我的第二次尝试:

  #!/usr/bin/env python
  from gi.repository import Gtk
  class Handler:
        def on_mainwindow_destroy(self, menuitem):
              print("destroy window")
              Gtk.main_quit()

        def on_menuquit_activate(self, menuitem):
              print("quit from menu")
              Gtk.main_quit()

        def on_menuabout_activate(self, menuitem, data=None):
              print("menu about activated")
              response = aboutdialog.run()
              aboutdialog.hide()

  builder = Gtk.Builder()
  builder.add_from_file("psn.glade")
  builder.connect_signals(Handler())

  window = builder.get_object("mainwindow")
  window.show_all()

  Gtk.main()

错误:

" Traceback(最近一次调用最后一次): 文件" psn_main.py",第21行,在on_menuabout_activate中     response = aboutdialog.run() NameError:name' aboutdialog'未定义"

答案 0 :(得分:0)

我使用以下代码使其工作。该功能由调用" on_menuabout_activate"的菜单项激活。它会向控制台输出调试消息。然后它从glade文件中获取aboutdialog-window并运行它:

  def on_menuabout_activate(self, menuitem, data=None):
        print("menu about activated")
        aboutdialog = builder.get_object("aboutdialog")
        aboutdialog.run()
