From PySide6.QtCore?

Is installing PySides6 all I need to import all these-
from PySide6.QtCore import QUrl, QTimer, Slot
from PySide6.QtWidgets import QApplication, QMainWindow, QToolBar, QLineEdit, QTabWidget, QLabel, QPushButton
from PySide6.QtGui import QAction
from PySide6.QtWebEngineWidgets import QWebEngineView

Or do need to install QT.Stuff also ?
Thanks for your Help…

I do not use pyside6 but with PyQt6 you get everything you need with the pip install.

And you can also check the Qt’s official quick start guide: https://doc.qt.io/qtforpython-6/quickstart.html
