我在 python 中编写了 openweathermap 站点 appindicator，但我只需要没有图标的指示器中的文本标签。但是当我离开“”时，会显示空图标。为什么，我只需要文本。在 Ubuntu 12.04 中，python-appindicator 不需要图标，如果离开“”则不加载空图标，但在 ubuntu 14.04 中留下空图标。如何禁用图标？有任何想法吗？

我发现的唯一方法是使用您自己的薄隐形图标或使用薄而微妙的现有 ubuntu png，例如 /usr/share/unity/icons/panel-shadow.png 或者您可以同时实现一点：

icon_image = os.path.dirname(__file__) + "/my_thin_inv_icon.png"
if not os.path.isfile(icon_image):
    icon_image = "/usr/share/unity/icons/panel-shadow.png"

self.ind = appindicator.Indicator.new("Weather",icon_image,appindicator.IndicatorCategory.APPLICATION_STATUS)
