#1

So I am making a applet for my personal use . The thing is that I can’t figure out how to connect the button to close the window . It says that the function I trow for second argument takes 0 positional arguments but 1 given. Any help? Here is the code:

#!/usr/bin/env python3

import gi
import time

gi.require_version("MatePanelApplet", "4.0")
gi.require_version("Gtk","2.0")
gi.require_version("Wnck","1.0")

from gi.repository import MatePanelApplet
from gi.repository import Gtk
from gi.repository import Wnck


def GetWindow():

    screen = Wnck.Screen.get_default()
    screen.force_update()

    window_list = screen.get_windows()
    active_window = screen.get_active_window()
    
    return active_window

    def CloseAction():
    action = Wnck.Window.close(GetWindow(),int(time.time()))

def ButtonsApplet(applet):
        
    MID_LEVEL = Gtk.HBox()

    close = Gtk.Button("close")
    minimize = Gtk.Button("minimize")
    maximize = Gtk.Button("maximize")

    close.connect("clicked",CloseAction)

    MID_LEVEL.add(close)
    MID_LEVEL.add(minimize)
    MID_LEVEL.add(maximize)
        
    applet.add(MID_LEVEL)
    applet.show_all()

def ButtonsApplet_Factory(applet,iid,data):
    if iid != "WindowButtonsApplet":
        return False
    ButtonsApplet(applet)
    return True

MatePanelApplet.Applet.factory_main("WindowButtonsAppletFactory",True,MatePanelApplet.Applet. __gtype__,ButtonsApplet_Factory,None)

Hi
Can you give the actual error message?
Also I think the forum formatting messed up your indentation.
Cheers

Yes it did . Here is the actual error

./window-buttons.py TypeError: CloseAction() takes 0 positional arguments but 1 was given

According to the examples I’m reading your callback function probably requires an argument “widget” even if it’s not using it.

So try the following:

def CloseAction(button):
    action = Wnck.Window.close(GetWindow(), int(time.time()))
