Question

我在python中写了openweathermap网站appindicator，但我只需要指针中没有图标的文字标签。但是当我离开“”然后给我看空图标。为什么，我只需要文字。在Ubuntu 12.04中，python-appindicator不需要图标如果离开“”然后不加载空图标，但在ubuntu 14.04中留下空图标。 如何禁用图标?? 任何想法？

我发现的唯一方法是使用您自己的瘦弱隐形图标或使用精简的现有ubuntu png，例如/usr/share/unity/icons/panel-shadow.png，或者您可以实现两者都很少：

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)

Gtk 3，python，appindicator，禁用标签附近的图标
