I am writing an applet for Ubuntu Budgie in python.I wrote some code,debugged with no errors, saved it and put the folder with the files in ~/.local/share/budgie-desktop/plugin directory so I can add it on panel.I tried to add it as an applet but nothing happened.So I am not sure if is running smoothly or not.
The code is in this link

#!/usr/bin/env python3

import os
import gi
import gi.repository
gi.require_version('Budgie', '1.0')
from gi.repository import Budgie, GObject, Gtk, Gio

class myapplet(GObject.GObject, Budgie.Plugin):

 __gtype_name__ = "myapplet"

 def __int__(self):

 GObject.GObject.__init__(self)

 def do_get_panel_widged(self, uuid):

 return myappletApplet(uuid)

class myappletApplet(Budgie.Applet):

 def __init__(self, uuid):

 Budgie.Applet.__init__(self)

 self.button = Gtk.ToggleButton.new("A")
 self.button.set_relief(Gtk.ReliefStyle.NONE)
 self.button.set_active(False)
 self.button.set_tooltip_text("Apple Menu")
 self.add(self.button)
 self.button.connect("clicked", self.button_clicked)
 self.show_all()

 def button_clicked(self):

 dialog = menu(self)
 response = dialog.run()

 dialog.destroy()

 #Create Menu
 menu = Gio.Menu()
 menu.append("About This PC", "app.about_this_pc")
 self.set_applet_menu(menu)

 #create an action for the option "About This PC" of the menu
 about_this_pc_action = Gio.SimpleAction.new("about_this_pc", None)
 about_this_pc_action.connect("activate", self.about_this_pc_cb)
 self.add_action(about_this_pc_action)



 def about_this_pc_cb(self, action, parameter):

 print("About This PC")




Gtk.main()

The applet is about a button in panel which every time i push it opens a dropdown menu with some options that can be activated.Like the "user-indicator-applet".

Right now I am stacked and I can not continue the code .Any help will be appreciated.
Thanks in advance.

I spot a typo!

def do_get_panel_widged(self, uuid):

It should be:

def do_get_panel_widget(self, uuid):

What is happening is that the typo version is just defining a function. Implicitly do_get_panel_widget is being called but it is a stub function so the applet will never appear.

With the correct name - you are now overriding the inbuilt stub function and calling out to your new applet code.

Secondly in your example you are missing a .plugin file - you need this to allow the module to run. The plugin file is this format:

[Plugin]
Loader=python3
Module=test
Name=test
Description=test description
Authors=your name
Copyright=© 2018 email address
Website=https://your-website.com
Icon=we-prefer-symbolic-icons-symbolic

Thirdly:

Don't have a Gtk.main() at the end of you main module - that just confuses a Peas based plugin - delete it

Fourth:

Use a Gtk.EventBox() to add your applet in - it is how budgie-desktop 10.4 plugins should now be written - example code below

 self.button = Gtk.ToggleButton.new()
 self.button.set_relief(Gtk.ReliefStyle.NONE)
 self.button.set_active(False)
 self.button.set_tooltip_text("Apple Menu")
 box = Gtk.EventBox()
 box.add(self.button)
 self.add(box)
 self.button.connect("clicked", self.button_clicked)
 box.show_all()
 self.show_all()

def button_clicked(self, *args):

Fifth:

Notice the button_clicked event is missing an argument - clicked events in GTK pass the button itself to the signal handler

Lastly - which I havent corrected for you - your clicked function has an uninitialised dialog - and you appear to want to display a Gtk Dialog. Don't! You will block the main thread of the panel.
