Bug description
Hello,
I have a simple class inheriting from PyGObject's Gtk.Window class. Pylint cannot Gtk.Window's add and show_all members, yet the code runs fine:
"""
The main window of the application.
"""
from typing import Tuple
import gi
gi.require_version("Gtk", "3.0")
# pylint: disable=wrong-import-position
from gi.repository import Gtk
# pylint: enable=wrong-import-position
class MainWindow(Gtk.Window):
"""
The main window of the application.
"""
WINDOW_SIZE: Tuple[int, int] = (500, 250)
MAIN_PADDING_PX: int = 10
FRAMES_VERTICAL_SPACE_PX: int = 10
INPUT_FILE_FRAME_LABEL: str = "Input file"
INPUT_FILE_BUTTON_LABEL: str = "Choose input file"
def __init__(self, title: str):
super().__init__(title=title)
self.set_size_request(*self.WINDOW_SIZE)
# --- Add widgets --- #
# Main container
main_box: Gtk.Box = Gtk.Box.new(orientation=Gtk.Orientation.VERTICAL,
spacing=self.FRAMES_VERTICAL_SPACE_PX)
self.add(main_box)
MainWindow.__pad_on_all_sides(main_box, self.MAIN_PADDING_PX)
# Input file picker
input_file_frame: Gtk.Frame = Gtk.Frame.new(label=self.INPUT_FILE_FRAME_LABEL)
main_box.pack_start(child=input_file_frame, expand=True, fill=True, padding=0)
hbox: Gtk.Box = Gtk.Box.new(orientation=Gtk.Orientation.HORIZONTAL)
input_file_frame.add(hbox)
self.input_file_button = Gtk.Button.new(label=self.INPUT_FILE_BUTTON_LABEL)
# --- Connect and show --- #
self.connect("destroy", Gtk.main_quit)
self.show_all()
@staticmethod
def __pad_on_all_sides(widget: Gtk.Widget, padding: int) -> None:
widget.set_margin_bottom(padding)
widget.set_margin_top(padding)
widget.set_margin_left(padding)
widget.set_margin_right(padding)Interestingly, if I remove the following line, pylint stops complaining. It looks like adding a member to the MainWindow class which inherits from Gtk.Window throws off pylint.
self.input_file_button = Gtk.Button.new(label=self.INPUT_FILE_BUTTON_LABEL)Configuration
I am using pylint's default configuration.Command used
pylint main_window.pyPylint output
************* Module main_window
main_window.py:34:8: E1101: Instance of 'MainWindow' has no 'add' member (no-member)
main_window.py:48:8: E1101: Instance of 'MainWindow' has no 'show_all' member (no-member)
------------------------------------------------------------------
Your code has been rated at 6.43/10 (previous run: 6.43/10, +0.00)Expected behavior
I would expect pylint to find these two members, as they clearly exist since the code runs fine.
