How can I change the application indicator label after delay?

Question

How can I change the Application Indicator label after delay

self.ind = appindicator.Indicator("new-gmail-indicator", "/usr/share/icons/ubuntu-mono-dark/status/16/ubuntuone-client-error.svg", appindicator.CATEGORY_APPLICATION_STATUS)

self.ind.set_label("SSH")

time.sleep(4)

self.ind.set_label("HSS")

The application runs but I only see the HSS label when running the application. I never see SSH.

The problem here is that you've got a single threaded application, and the sleep is blocking it, thus the AppIndicator library doesn't get a chance to update the label. What you need to do for your timeout is use GLib's timeout function to set up a delay, and change the label in that callback. The code would probably look something like:

def set_label(self):
    self.ind.set_label("SSH")
    GLib.timeout_add(4, self.respond_to_timeout)

def respond_to_timeout(self):
    self.ind.set_label("HSS")

Good luck!
