ValueError: Namespace AppIndicator3 not available

[munikarmanish]

I installed xfce4-indicator-plugin and pip requirements. And sudo make install ran successfully. But when I run nepcal_applet, I get the following error.

Traceback (most recent call last):
  File "/usr/local/bin/nepcal_applet", line 11, in <module>
    gi.require_version('AppIndicator3', '0.1')
  File "/usr/lib/python3.5/site-packages/gi/__init__.py", line 102, in require_version
    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace AppIndicator3 not available

Did I miss something?

@munikarmanish hey Manish, can you try installing gir1.2-appindicator3? I thought it was available by default but maybe not.

sudo apt install gir1.2-appindicator3-0.1

If its not available, try the autocomplete or perform apt-cache search for appindicator3. If that works, I will update the readme (or I can accept your pull request if you wanna update it)

[munikarmanish]

@techgaun Okay, finally managed to install all dependencies. BUT.... I only see the flag in the panel. 😕

[techgaun]

@munikarmanish oh well did you have to install gir1.2-appindicator3-0.1? If yes, I will put a note on readme.

Also, thats weird. didn't happen to me on xfce. What's the flavor of linux you're using? I'll see if I can make it work tomorrow. I suspect this might be due to the limitation of width available.

[munikarmanish]

I use Arch Linux and I had to install libappindicator-gtk3 to make it run.

[techgaun]

Okay nice yeah I'll try on Arch tomorrow and see if I can get it working

[techgaun]

@munikarmanish I just got Arch installed and I can replicate the issue. Am trying to figure out how we can add the applet to indicator instead of notification area. It seems that the notification area width can not be set somehow.

Below is for my personal reference as I'm trying to play around with the :

cat /home/techgaun/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml
...
<property name="plugin-16" type="string" value="indicator">
      <property name="known-indicators" type="array">
        <value type="string" value="/home/techgaun/nepali-calendar-indicator/nepcal_applet.py"/>
      </property>
      <property name="single-row" type="bool" value="false"/>
      <property name="align-left" type="bool" value="false"/>
      <property name="blacklist" type="array">
      </property>
    </property>
...

Values probably need to be namespaced such as com.canonical.indicator.bluetooth

bro, is there any way to install in arch kde?

[diwasx]

Gtk-WARNING **: Theme parsing error: gtk.css:73:46: The style property GtkScrolledWindow:scrollbars-within-bevel is deprecated and shouldn't be used anymore. It will be removed in a future version

getting this error

[techgaun]

@diwasx sorry for the delay. I've not really tried it on arch kde. The warning you mention above is just a warning (although it should be fixed and I will try to fix that). What else do you get? Is it completely broken?

[diwasx]

doesnt preceed after that, it stucks there

@munikarmanish hey Manish, can you try installing gir1.2-appindicator3? I thought it was available by default but maybe not.

sudo apt install gir1.2-appindicator3-0.1

same case when i installing battery-monitor on ubuntu 18, this command will fix it. cheers
