В прошлом посте говоря "Все вызовы теперь одинаковы" я несколько слукавил. Всё-таки есть в этом зоопарке версий некоторая несовместимость вызов которой просто так не унифицировать. Эти моменты вынесены в отдельный модуль QtCompat (compatibility). Там не так много функций но они довольно полезны.
Этот модуль содержит унификаци модуля shiboken2, функций loadUi, translate и несколько переименованных функций классов или изменённую сигнатуру аргументов и возвращаемых значений. Это единственное исключение из правила когда вам потребуется где-то изменить свой код кроме импортов и этот код не похож на обычный код PySide2.
Например, в PyQt4 и PySide есть метод
QHeaderView.setResizeMode
Для PyQt5 и PySide2 они были благополучно переименованы в
QHeaderView.setSectionResizeMode
Чтобы применить этот метод следует использовать такой код
from Qt import QtCompath
header = self.horizontalHeader()
QtCompat.QHeaderView.setSectionResizeMode(header, QtWidgets.QHeaderView.Fixed)
Унификация загрузки UI файлов:
# PySide2
from PySide2.QtUiTools import QUiLoader
loader = QUiLoader()
widget = loader.load(ui_file)
# PyQt5
from PyQt5 import uic
widget = uic.loadUi(ui_file)
# Qt.py
from Qt import QtCompat
widget = QtCompat.loadUi(ui_file)
Хорошо что таких моментов не много и их легко запомнить.
Полный список можно посмотреть в таблице.

📰US and Russia agree to resume regular military contact
The United States and Russia have agreed to reestablish high‑level military‑to‑military dialogue for the first time in over four years, both powers announced late Thursday.
The deal was struck in Abu Dhabi, on the sidelines of trilateral talks between the U.S., Russia and Ukraine on ending the war, and was announced by U.S. European Command. The channel will
“provide a consistent military‑to‑military contact as the parties continue to work towards a lasting peace.”
High‑level military communication was suspended in the fall of 2021, shortly before Russia’s full‑scale invasion of Ukraine. Since then, there have been repeated close calls: Russian drones and warplanes edging into NATO airspace, U.S. unmanned systems operating over the Black Sea and Syria, and an almost constant risk of misunderstanding turning into escalation.
Now, the two sides say they want to avoid miscalculation and unintended escalation. The U.S. stresses that such dialogue is
“an important factor in global stability and peace, which can only be achieved through strength,”
and that it will increase transparency and help de‑escalate.
Diplomacy, or nuclear‑treaty bargaining?
The announcement came hours after the New START treaty expired, leaving the U.S. and Russia without a formal cap on their nuclear arsenals for the first time in half a century. Russia has said it still wants to talk, and the Kremlin has offered to keep observing the treaty’s limits — but only if the U.S. responds positively.
Axios reports that negotiators were closing in on a deal in Abu Dhabi to keep key provisions in place while both sides work toward a new framework, which Trump has described as a “new, improved, and modernized” treaty.
The Trump factor
President Donald Trump, who has repeatedly called for closer ties with Moscow, framed the move as a win for his approach: normalizing relations with Russia while pressing for a Ukrainian peace deal and a new arms‑control framework.
But in practice, the renewed hotline is less about friendship and more about necessity: when two nuclear powers hover over the same war zone, the only safe channel is one that stays open — even if both sides keep their fingers on the trigger.
