KDE shows a -ve sign witout any numbers when the Unity launcher count is negative

Help

I am using Unity’s launcher count API to show temperature from an weather app in the launcher.

When the temperature is negative, KDE just shows a -ve sign.

In comparison, Plank dock shows the correct number.

Here is a minimalistic example to recreate the issue. Save this python script, and run it. It should change the launcher count of firefox, and add a badge of -10. But the badge will only show up as “-”.

import dbus
import dbus.service
import dbus.mainloop.glib

from gi.repository import GObject

class Service(dbus.service.Object):
   def __init__(self, message):
      self._message = message

   def run(self):
      dbus.mainloop.glib.DBusGMainLoop(set_as_default=True)
      bus_name = dbus.service.BusName("com.example.service", dbus.SessionBus())
      dbus.service.Object.__init__(self, bus_name, "/com/example/service")        

      self._loop = GObject.MainLoop()
      GObject.idle_add(lambda: self.Update("application://firefox.desktop", {"count-visible": True, "count": dbus.Int64(-7)}))

      self._loop.run()
   
   @dbus.service.signal(dbus_interface="com.canonical.Unity.LauncherEntry", signature='sa{sv}')
   def Update(self, app_uri, properties):
        print(app_uri, properties)

if __name__ == "__main__":
   Service("This is the service").run()

I would be happy to open a bug report. But I am not sure which project I should report it against. Any tips?

Hi - I believe that would fall under the “plasmashell” Product, and the “Task Manager and Icons-Only Task Manager widgets” Component.

It looks like the relevant code would probably be somewhere in one of these two files, if you’re feeling adventurous :slight_smile:
