以编程方式将新菜单项添加到菜单项PyGObject? [英] Programatically add new menu items to menu item PyGObject?

问题描述

我在wxPython中进行了设置，但是现在我要为GTK3/PyGObject重写它，而我在这里有些迷失.基本上，我的代码扫描目录，并将文件名添加到菜单项.我无法在PyGObject中使用它.这是当前代码:

I had this set up in wxPython, but now I'm rewriting it for GTK3/PyGObject, and I'm kind of lost here. Basically, my code scans through a directory, and adds the names of files to a menu item. I can't get it to work in PyGObject. Here is the current code:

# Populate profiles menu
        profileMenu = self.builder.get_object("profilesMenu")
        profiles = os.listdir("/etc/netctl/")
        # Iterate through profiles directory, and add to "Profiles" Menu #
        for i in profiles:
            if os.path.isfile("/etc/netctl/" + i):
                profile = profileMenu.set_menu_item(i)

我尝试了各种profileMenu.*想法.我尝试的第一个是set_submenu，它返回以下错误:

I've tried various profileMenu.* ideas. The first one I tried was set_submenu, which returns the following error:

[cody@cody-arch NetGUI]$ sudo python main.py 
Traceback (most recent call last):
  File "main.py", line 466, in <module>
    netgui()
  File "main.py", line 70, in __init__
    self.InitUI()
  File "main.py", line 140, in InitUI
    profile = profileMenu.set_submenu(i)   
TypeError: argument submenu: Expected Gtk.Widget, but got str

当前仅说set_menu_item不存在，因此显然无法正常工作.我应该怎么做才能解决这个问题?我完全迷路了.我知道为什么set_submenu不起作用，不知道如何解决.如何将文件名设为Gtk.Widget?

The current one just says set_menu_item doesn't exist, so obviously that won't work. What should I try to do to fix this? I'm completely lost. I know why set_submenu doesn't work, I don't know how to fix it. How would I make a filename a Gtk.Widget?

推荐答案

您正在寻找的是append().而且，常见的层次结构是:

What you're looking for is append(). Also, the common hierarchy is:

• GtkMenuBar
  • GtkMenuItem
    • GtkMenu
      • GtkMenuItem
      • GtkImageMenuItem
      • GtkCheckMenuItem
      • GtkRadioMenuItem
      • GtkSeparatorMenuItem
      • GtkMenuBar
        • GtkMenuItem
          • GtkMenu
            • GtkMenuItem
            • GtkImageMenuItem
            • GtkCheckMenuItem
            • GtkRadioMenuItem
            • GtkSeparatorMenuItem

            代码的相关部分是:

                content = [
                    'Path to file 1',
                    'Path to file 2',
                    'Path to file 3',
                    'Path to file 4',
                ]
            
                # Create menu
                menu = Gtk.MenuItem(label='My Menu {}'.format(num))
                menu.set_submenu(Gtk.Menu())
            
                for p in content:
                    menu.get_submenu().append(Gtk.MenuItem(label=p))
            
                self.menubar.append(menu)
                menu.show_all()
